Planet Name: Artemis 

Untitled_Artwork.jpg 

(Drawn by yours truly. I know, it's a masterpiece. No need to shower me in your praise. I didn't draw the rings because I could not figure out how to make a straight line)

Discovery:

Discovered in 1614 by Leonardo Dara, a Rhavanese Salvian astronomer on a research mission in an observatory located in the Đuôi Rồng Báo (ຫາງເສືອດາວມັງກອນ) mountains, northern Rhava, commonly known as the Dragon Leopard's tail. Using a telescope he was able to spot a green dot in the sky, which was too big to be a moon and too small to be a star. Mistaking it as a heavily forested planet, he named it after the Greek goddess of the hunt, Artemis because he believed the forests would be filled with animals for hunting. 

 

In 1643 a yellow object was spotted orbiting the planet, and was named Apollo. 

 

In 1923 it was discovered not to be forested, but actually had a green gaseous atmosphere. Since then it’s second largest moon, Actaeon, was discovered as well as 43 other moons.

 

Information:

The planet Artemis is the sixth planet from the San, and is approximately 9.3 AU from the San. It has 45 moons, Apollo which is the biggest and is colored an emerald green, with swirling storms and hurricanes enveloping the surface.

 

 Artemis has a surface area of 16.13 billion square miles. It has a diameter of 71,654 miles. The planet takes 27 years for it to orbit the San. 

 

Artemis has one set of rings, with 5 layers colored a shade of yellow, which is thought to be from one of Artemis’s moons crashing into the planet, the debris orbiting the planet creating the rings. Large amounts of chlorine give the planet it’s green tint and its thick atmosphere keeps the planet at a very hot temperature. Storms and hurricanes are common across the surface, while there is a very thin layer of rock forming the crust. 

 

Satellites: 

Artemis has 45 moons, the largest of which are Apollo and Actaeon. 

 

Apollo is Artemis's largest natural satellite, and is slightly larger than the Mun. It’s surface is covered with hundreds of volcanoes as well as many mountains. The yellow tint of Apollo is from large amounts of sulfur.

 

Actaeon is Artemis’s second largest moon, and is the same size as the Mun. Actaeon is named after the man in Greek mythology Artemis turned into a stag and hunted. Thought to be colored by the blood of the stag, it is actually from large amounts of iron on the surface that has oxidized. Actaeon does not have much geological action and is relatively flat, part from mount Lyssa which is roughly the size of Mount Saint Helens irl.

Submission for the Luxaar System

The Luxaar System is the home star system to Humanity and their home wurld Eurth. The central star, named Lux, is a G-type main sequence star identical to the Sun. The Luxaar System is home to 11 planets:

▪ Hyperion
▪ Balder & Nanna
▪ Eurth & Manne
▪ Ostara
▪ Holda
▪ Donar
▪ Woden
▪ Friya
▪ Adlas
▪ Sius
▪ Japetus

Note:
M🜨 = Eurth Masses
R🜨 = Eurth Radii (size)
D☾ = Distance between the Eurth and the Moon
M♃ = Jupiter Masses
R♃ = Jupiter Radii (size)

Hyperion
Hyperion is the closest planet to Lux and was only discovered in 1860 by an Anglian astronomer and later verified in Seylos and Tagmatium. The astronomical community at the time agreed to name it Hyperion, after the Aroman Titan of the Sun. It's late discovery is due to its incredibly tight orbit around Lux, leaving it a molten hellscape tidally locked to Lux. Rapid silicon-vaporised winds eroding what little landscape is left on the charred planet. Several new age Christian sects have also been known to call the planet 'Hell' or 'Hades' as the literal physical manifestation of the underwurld though the Catholic Diarchy has been recorded in numerous instances as denying Hyperion as Hell as a place. The most recent recording was in 2018 when the Iverican Pope stated that 'Hyperion was made with the same hands God used to create the Eurth, it is no more damned than the soil you treaded into my Cathedral'.

Balder and Nanna
Balder was never 'discovered' per-say as it is visible to the naked eye in the night sky, however Nanna was only first recorded to exist in 300 AD by the north Argisian Germanic tribes, which is where both of their names come from as son and daughter-in-law of Woden/Oid respectfully. Balder is most well known for its massive craters across its landscape, which where created 1.5 billion years ago when a dwarf planet would have collided with the young Balder causing it to tip onto its side. The matter that was ejected into orbit eventually coalesced into Nanna. Although Balder itself is a prime target for future Human exploration due to its closeness to Eurth and low gravity, the proximity and size of Nanna makes calculating safe orbital trajectories incredibly difficult. Nanna's red colouration primarily comes from the high iron oxide content in its crust and is the largest moon in ratio to its planet in the Luxaar System.

Eurth and Manne
Manne is the Eurth's moon, a yellowish orange crater-filled landscape with white streaks across the surface. Manne was a dwarf planet that was captured by Eurth, with Manne’s old moon being destabilised and collided with Eurth providing most of Eurth’s water and forming the Sunset Archipelago controlled in the modern day by the Sunset Sea Islands.

Ostara
Like Balder, Ostara was never 'discovered'. The planet's unique green and red colouration comes from the green and red iron rust across its surface and the only known body to have Iron(III) cations in high concentrations. This is due to Ostara possessing a thick halogenic-CO2 atmosphere in the past, however by the present day it has been reduced to a trace green atmosphere. When telescopes were first invented, its green patches were mistaken for forests. Ostara became legendary in status from the 1600s until the mid 1900s, many considering it the home of the gods or Eden. It was only with more powerful telescopes in the 1900s and the Easter Probe missions was the once-thought lush planet revealed to be the dead and dusty wurld it is now. However, the planet is still an anomaly within the scientific community as the high concentrations of halogens in its past and present have yet to be explained and many Sci-Fi alien invasion films still have "Ostarians" invade Eurth to the point of cliche.

Holda
Holda was never discovered as it was visible in the night sky and is actually the brightest planet in the night sky. Its surface is covered in kilometres thick ice with a theorised subsurface ocean. No missions have been sent to land on Holda, however there exists plans to send drilling probes to penetrate the icy crust to confirm its interior oceans. Holda holds the record for the coldest planetary surface temperatures in the whole Luxaar system at -264°C / -443°F.

Woden
The cooler Donar. Woden is a small ice giant sandwiched between its two larger siblings, and possesses an expansive ring system which was thought to have been produced by one of its larger moons coming too close and torn apart due to tidal forces. A shepherd asteroid moon exists in between the rings which has been determined to be made up almost entirely of heavy metals such as iron and platinum and is hypothesised to be the remnant core of the original moon. Woden also has a large dark stripe across its southern hemisphere following the equator which could be seen from any of its moons. It's blue colouration was known since ancient times with many cultures speculating on it being a water wurld or made up of blue jewels.

Photo taken from the Vili Probe, which famously was redirected into Woden's clouds and burned up in 2013. Initially the Embla probe was meant to land on its moon of Vili, however whilst in the middle of its travel to Woden it was discovered Vili had no been properly sterilised before lift off. The scientific community deemed it too great a risk for Eurth-origin bacteria to potentially infect the moon, thus the Embla probe was burned up in Woden's atmosphere. The above picture taken a day before contact was lost. The new Ask probe is to land on the moons of Vili and Ve later this decade.

Friya and Adlas
Friya is a liquid giant that is in a 1:1 resonant orbit with the small planet of Adlas. Friya has a beige cream colouration and is generally perceived as quite a boring planet with generic characteristics, however its moons of Hnoss and Gersemi are unusually large at 0.107 Eurth masses and 0.0553 Eurth masses respectfully. Hnoss is covered in ice, whereas Gersemi is dark grey. Adlas is unique for being the only terrestrial planet other than Eurth to have a significant atmosphere at 1.18 atmospheric masses, although is primarily made up of CO2 and methane. Its thick atmosphere combined with its low gravity means Human-powered flight is theoretically possible on the small planet. Adlas also possesses a small asteroid moon called Calypso with a 20.8 hour orbital period around Adlas.

Sius
If there is one planet that deserves the title of ‘most boring planet in the Luxaar System’ its Sius, but it is certainly one of the prettiest!. Sius was discovered in the 1830s simultaneously by a Kirvinan astronomer and a group of astronomers in Tagmatium. The Kirvinan wished to have called the planet the “Konstantin Sidis” after the Grand Exarch Konstantinos Damoras that reigned in the 1860s, however the Tagmatine group disagreed. Eventually they settled on ‘Coeus’ (often Anglicised to ‘Sius’).

Japetus
Ice Giant discovered in 1855 by a group of scientists and astronomers across the wurld at a gathering in Te Kuiti, Gallambria. Initially the group wished to call the planet Enotita (“Unity” in Greek) however several of the scientists from Anglian and Aroman nations conspired for the name ‘Iapheth’ after the Son of Noah Japheth, thus when they returned to their nations they told them that 'Iapheth' was the chosen name. For several decades both names Enotita and Iapheth were used across the wurld, but grew ever more controversial in the scientific community. Eventually in 1910 a panel of scientists and astronomers came together to decide which of the two names to use, 2 years later at the end of the panel they decided to toss out both names and instead use Japetus with both previous names being given to two of its moons.

Japetus has numerous moons (Lunar Enotita, Lunar Iapheth, Prometheus, Epimetheus, Menoetius) at awkward eccentricities and inclinations, which is assumed to have occurred when a now lost gas giant flung past Japetus in the early ages of the Luxaar system.

Oh boy, I freaking love space and while I’m no expert on it, this is right up my ally in terms of my interests!

So without any further ado, I present to you the Aril system!

ARIL SYSTEM

The Aril system is a star system of 8 planets, only 7 of which are native to the star system (we will get to that later).

Planet names are borrowed from Etruscan mythology.

Moons are not mentioned - but I’d imagine any number of these planets could have their own moons. Contributions from others would be very welcome for those moons.

Nortia

CoRoT-7c.jpg
Image: CoRoT-7c as it appears in the software Celestia.

The closest planet to Aril. It’s a small rocky planet close to the star. Owing to its closeness to the star, it has a very slow rotational speed, and will likely naturally become tidally locked to the main star in a few million to a few billion years. It is roughly ⅓ the side of our real-life Eurth, and comparable to mercury rl.

 

Mass: 0.048 Eurth’s (2.87E+23 kg)
Radius: 0.365 Eurth’s (2328 km)
Density: 5.42 g/cm3
Orbital distance: 0.382 AU
Year length (in rl time): 2.89 months
Other features:

  • Slow rotational speed
  • High surface temperature

Maris

Gliese_581_c_(Celestia).JPG
Image: Gliese 581c as it appears in the software Celestia.

The second planet in the Aril system. This is also a small rocky planet, roughly half the size of Eurth. Due to its low mass and density, it doesn’t have a thick atmosphere. However, evidence points to it having an atmosphere and being much warmer than it currently is in the past. The current working theory is that while the planet may have once had an atmosphere much like Eurth’s, its magnetosphere disappeared roughly 5 billion years ago leading it to lose its atmosphere due to stellar winds. Its surface is covered in dust, mostly ground up rocks, and the tiny atmosphere that there is left allows there to be regular dust storms. Consider this similar to our real life Mars.

 

Mass: 0.107 Eurth’s (6.42E+23 kg)
Radius: 0.532 Eurth’s (3390 km)
Density: 3.93 g/cm3
Orbital distance: 0.630 AU
Year length (in rl time): 6.06 months
Other features:

  • Low temperature despite location due to atmosphere not being able to retain heat
  • Dust storms can happen from time to time

Eurth

This is the Eurth we all know and love. I did rename the moon to Losna, but kept most of the details the same. I think Losna is slightly further away than the moon is irl, but that’s about the only difference, and it could easily be substituted with the rl distance.

Laran

sXwQOUk.png
Image: Rendition of a tidally locked habitable planet, found on the Universe Sandbox forums.

Slightly larger than Venus, Laran has an atmosphere and magnetosphere similar to Eurth and a ground soil composition similar to Eurth as well. However, it has one major difference - the planet is tidally locked. This likely happened after a massive collision early in the planet’s history. As a result, the side constantly facing the star is a massive desert, while the side facing away from the star is a frozen land. However, in-between these extremes, there are rings of potentially habitable areas with different climates depending on how warm they are.

 

Mass: 0.819 Eurth’s (4.89E+24 kg)
Radius: 0.911 Eurth’s (5802 km)
Density: 5.98 g/cm3
Orbital distance: 1.55 AU
Year length (in rl time): 1.94 years
Other features:

  • Within habitable zone
  • Tidally locked, so there are rings of different habitable climates that change depending on the temperature, from the hot side to the cold side.

Asteroid belt

I won’t put much details here, but I do believe that having an asteroid belt somewhere would massively increase the potential for space exploration. As such I would put one here no matter what. Some dwarf planets can also go here, perhaps incorporating ideas for dwarf planets from other posts here. The asteroid belt starts at about 2.31 AU and ends at about 3.76 AU.

Satre

A gas giant and the first planet in the outer Aril system. The planet is visually similar to Jupiter, save for one extremely distinct feature. It has a massive ring system that extends 701,647 km. This ring system would be visible on Eurth’s skyline, with a size of 3 arcminutes at most and 2 arcminutes at least. This means it could be visible with the naked eye from Eurth, and at its largest would appear 1/10 the size of the moon. Think of it as Jupiter and Saturn combined.

 

Mass: 1.51 jupiter’s (2.87E+27 kg)
Radius: 1.02 jupiter’s (71,117 km)
Density: 1.9 g/cm3
Orbital distance: 6.36 AU
Year length (in rl time): 16.0 years
Other features:

  • Large gas giant
  • Large ring system that could be visible from Eurth with the naked eye
  • Likely has a moons, but I will let others choose the details for those.

Turan
83_Leonis_Bc.jpg

Image: 83 Leonis Bc as it appears in the software Celestia.

Another gas giant, similar in composition to Saturn. However, this planet would not have many rings. If it has any rings it would likely be similar to that of Jupiter, in that it would be a single thin ring that is not easily visible. However, this planet would have many moons which could be explored by players.

 

Mass: 0.513 jupiter’s (9.74E+26 kg)
Radius: 10.9 Eurth’s (69,686 km)
Density: 0.687 g/cm3
Orbital distance: 10.4 AU
Year length (in rl time): 33.4 years
Other features:

  • Gas giant, similar to Saturn without rings
  • Many moons to be explored, but I will let others choose the details for those.

Orcus

Planet_HD_171028_b.png
Image: HD 171028 b as it appears in the software Celestia.

The final gas giant in the Aris system. Its atmosphere has traces of water, ammonia, and methane. As a result, it has a teal color. The planet also has a small ring about it, similar to that of Neptune but slightly smaller.

 

Mass: 29.7 Eurth’s (1.77E+26 kg)
Radius:7.31 Eurth’s (46,601 km)
Density: 0.418 g/cm3
Orbital distance: 25.6 AU
Year length (in rl time): 130 years
Other features:

  • Teal planet with some rings
  • Has a few moons, but not as many as Turan.

Vanth

The last planet in the Aril system, but the odd one out of the bunch. It is also the most distant planet in the system, and likely the final one to be discovered. It’s a rocky-ice planet, but that’s not its claim to fame. Despite its Eurth-like size, the planet has an orbit vastly different from that of the rest of the planets. That is for a simple reason - this planet is not originally from this star system! It is a captured rogue planet that originated from another star system.

 

Mass: 0.671 Eurth’s (4.01E+24 kg)
Radius: 0.866 Eurth’s (5647 km)
Density: 5.31 g/cm3
Orbital distance (average): 84.4 AU
Orbital distance (periapsis): 37.1 AU
Orbital distance (apoapsis): 132 AU
Orbital eccentricity: 0.478
Year length (in rl time): 775 years
Other features:

  • Rocky and icy, perhaps has frozen water
  • Rogue planet that was captured by Aril’s gravity after drifting too close
  • Extremely cold surface

Other potential objects

There are a number of other objects outside of Vanth that could be proposed. These include other dwarf planets, but also much more. There would likely be something similar to the Kuiper Belt or Oord Cloud in this solar system as well, containing countless comets and planetesimals.

NOTE: Images used are simply the closest stuff available I could find online, and not meant to be actual images used in RP. It is merely to illustrate a point. Credit is given to where I obtained the images from. The images where they mention the software Celestia have also been obtained from screenshots uploaded to Wikimedia Commons.

SUBMISSION FOR THE DOUBLE PLANETS OF PETRUS & ANDREUS

spacer.png

(Graphic showing the proposed orbits of Petrus and Andreus, and their moon, Paulus. Graphic is not proportional.)

 

NAMING

The work-in-progress names of these planets were decided to be Petrus and Andreus, named after two of the Twelve Apostles in Christianity: Saint Peter and Saint Andrew. The even more WIP name of their singular moon is Paulus, named after Saint Paul the Apostle (who was not one of the Twelve Apostles). The overall name of the Petrus-Andreus system would be the Apostolic System.

Petrus and Andreus were named such because they are very closely related planets, so they were named after the brothers St. Peter and St. Andrew. Paulus has very little reason to be named after St. Paul besides the fact that I wanted another name from Christianity for the moon. Another considered name for this moon was Ionah or Ionas, after Jonah, the father of the Peter and Andrew, but this name was tossed out because it might have been confused with the prophet Jonah. The name Apostolic System was chosen because of St. Peter and St. Andrew's status as Apostles of Christ.

I believe that Paulus should probably have its name changed if it is chosen for the Sanar System. What the name could be changed to is up to debate because I was unable to find a better name that I was satisfied with. If the names Petrus and Andreus were kept, I think their moon should also be named after a significant figure in the Christian Bible.

 

PROPERTIES

The most important and noteworthy property of these double planets is that they are double planets. This means that Petrus and Andreus orbit each other around their barycenter and are roughly similarly sized (as shown in the graphic above). Petrus would have a radius of about 2700 km, and Andreus would have a radius of roughly 2450km. Regarding the planets' moon, Paulus orbits around both of them in an elliptical shape. Paulus's orbit isn’t the most stable in the universe, but it can manage. Paulus is much smaller than either planet, and it would have a radius of about 15km. 

The planets should take about 7.5 Eurth days to orbit around the barycenter, and they would also be tidally locked to one another. Both planets would be bluish in color, caused by their copper-rich soil and oxygen-rich atmospheres. Of the two, Andreus would have a thicker atmosphere and would be rich in resources, while Petrus would have a thin atmosphere and be less resource rich. Neither planet would have a source of water in any state, but Paulus would be entirely covered in ice.

If the Apostolic System illustrated above is deemed too improbable, a system closer to the Pluto-Charon system (as shown in the graphic below) could be adopted. However this would mean the considerable downsizing of Andreus, either in size or density, to account for the change in barycenter. In this setup, Paulus could probably remain, but it could also be scrapped.

Short Note on Location

This won’t get its own section because it is relatively short. If the Apostolic System is picked up, I believe it should be the inner planets farthest from the San, but the decision is up to the community since I have no strong opinions on any location.

The deadline has been met and the competition is now over!. The staff will begin the process of judging and ranking submissions to find our top four to receive their prize. That does not mean more ideas are not welcome - they will just not be counted towards the rankings and will not be given prizes. So if you have any ideas you still wish to publish and possibly squeezing in through the gaps to join the Sanaar System then by all means still submit, however submissions posted in December will be taking priority over their specific star system niches.

We are still missing:
- Detailed asteroid belt(s)
- More dwarf planets (beyond the planets and within asteroid belts)
- More moons of gas giants (collaborating with pre-existing gas giant submissions is not required if the moon(s) submission is malleable enough to work with differing gas giants)

Good evening everyone. Two points we'd like to make.

1. As mentioned above by @Xio, we are still in the parked for some missing elements.

2. Now that biggest cartography project is over, the plan is to start making the final list once exam season is over. (A draft of one exists - no peeking, though!) Expect the results around mid-February — assuming things go smoothly
