Let's make a summary of this thread, our planets and stars still need names
Star system summary:
Main star: G star class, a little smaller than the Sun to compensate the influence of the second star.
Planet 1: Tide locked, close to star. Iron planet
Planet 2: Old drifter, much orbital debris. Chthonian planet
Planet 3: hot gas planet, Blue hot Jupiter
Planet 4: Earth-like but 30% bigger, orbit close to CWBP 2, two moons. Silicate planet
Planet 5: CWBP 2 planet: 2 satellites, the second is in another dimension. Silicate planet
Planet 6: Ice rock smaller than Venus. Silicate planet
Planet 7: Beige gas giant. Jupiter-like (ammonia)
Planet 8: large terrestrial planet, large oceans covered by ice
Planet 9: Ice giant, appear white-blue, larger than Jupiter
1-A planet orbiting close to the star. It is tide locked. The planet is so close that it is difficult to see it from our world. Under the right conditions, at dawn/dusk, a small and reddish sphere appear in the sky close to the star. It's possible to see her only for a very short moment in the best scenario. Being close to the star mean it's a lot hotter on the tidal locked face, but the other side is freezing cold. And finally, the tidal energy generates heat in the planets resulting in a lot of geothermal activities.
Diameter: 6578 km
Mass: 0,24 Earths
Density: 9,42 g/cm
Hill sphere: none
Temperature: 443 °C
Distance form main star: 25 m km
Orbital period: 25 days
2- The second planet is an old one. We don’t know where it came from but it could be older that our star. She probably drifted for some time in space before gaining the actual orbit. Her obit is pretty eccentric. Temperatures on the planet are extreme since the rotation takes more than 3 terrestrial years to complete and has a strong inclination. The center of the planet is almost completely cooled off. The planet has near to zero magnetic fields given its slow rotation and the small size of its melted core. Is has a very thin atmosphere with different gases and water. During its life, many objects came in collision with the planet. That's why there are so many craters and water in the atmosphere. There is also a lot of debris floating around the planet. Some of them rotate at more than 1 million km but most are orbiting closer in a planetary ring. The color of the planet is a pale gray and she is smaller than Venus. This planet is visible with naked eyes. It is a chthonian planet that lost the outer layers of gas. Only the dense metal rich core of the planet is still there.
Diameter: 11 399 km
Mass: 0,78 Earths
Density: 6,01 g/cm
Hill sphere: 0,4 m km
Satellites: a lot of debris small and larger
Temperature: 256 °C
Distance form main star: 43 m km
Orbital period: 56,3 days
3: The third planet is a gas giant known as a Hot Jupiter. The planet mass is about the same as Earth but it’s mostly made of hot gas. Hot gases take a larger volume. Interestingly, the planet formed away from the star and moved probably during the collapse of the other star. The planet lost some of the outer layers of gas over time but it’s almost stable now.
Diameter: 32 000 km
Mass: 2,75 Earths
Hill sphere: 1 m km
Satellites: a few
Temperature: 106 °C
Distance form main star: 87 m km
Orbital period: 162 days
Color: Deep blue
4- The fourth planet is orbiting pretty close to our world and is in the habitable zone too. The gravity is stronger which allows for a thicker and denser atmosphere. The planet is more inclined (30 degrees) so climates are more extreme between the seasons.
Diameter: 18 708
Mass: 3,16 Earths
Hill sphere: 1,5 m km
Satellites: 2 confirmed
Temperature: 27,6 °C (lifeforms)
Distance form main star: 137 m km
Orbital period: 324 days
1 day= 36 h
Color: like Earth
Gravity: 1,4 times the gravity of Earth
Diameter: 4051 km
Mass: 2,57 Moons
Density 5,43 g/cm
Distance: 81 500 (is tide locked)
Orbital period: 36 h
Diameter: 1501 km
Mass: 0,054 Moon
Density 2,26 g/cm
Distance: 330 000 km
Orbital period: 12,3 days
5- CWBP 2 world ...(advanced lifeforms)
6- The sixth planet is a cold planet. It's almost all covered with a thick layer of ice which reflect a lot of light into space. It is said that it can also reflect the light of the old star.
Diameter: 11 265 km
Mass: 0,68 Earths
Density: 5,43 g/cm
Hill sphere: 1,5 m km
Temperature: -36 °C (is at the limit of the habitable zone but too cold)
Distance form main star: 1,38 AU
Orbital period: 1, 62 years
Color: pale gray
Gravity: 0,88 time the gravity of Earth
7- The seventh planet is a beige gas giant (Sudarsky Class I) probably made of ammonia and methane.
Diameter: 104 210 km
Mass: 74,5 Earths
Hill sphere: 12 m km
Satellites: could have a lot
Temperature: -80 °C
Distance form main star: 2,23 AU
Orbital period: 3,33 years
8- The 8th planet is a large terrestrial planet: This planet is much larger than the 4th planet, making it visible at that distance. A solid and dense core is covered by an ocean several kilometers deep and recovered with a thick layer of ice.
Diameter: 24 900 km
Mass: 3,25 Earths
Hill sphere: 12 m km
Satellites: could have some
Temperature: -171 °C
Distance form main star: 5,85
Orbital period: 14,1 years
9- The 9th and last planet is a gas giant. In fact, it’s a super Jupiter planet almost twice the size of Jupiter but with much lighter. It can also be called a puffy planet because of its low density. Mostly made of methane.
Diameter: 234 130 km
Mass: 0,39 Jupiter
Density: 0,11 g/cm
Hill sphere: 75 m km
Satellites: a lot
Temperature: -185 °C
Distance form main star: 10,8 AU
Orbital period: 35,3 YEARS
Color: pale blue
The Second Star
Is making the planet 8-9 Kelvin hotter. The luminosity of the star has a variation of 7% depending the season.
The second star has her own smaller system but it’s not visible from our planet.
-6 is the apparent magnitude of the star as seen from the planet when the distance is 75 AU.
It’s nearly 3 times brighter than Venus and 600 times fainter than the full moon.
This white dwarf is probably the result of a collapsed star. It’s been such a long time that the nebula surrounding it has disappeared. Invisible but some particles are still there. The planet have been irradiated for almost 10 000 years with particles and debris. It was so hot that the surface of the planet crust melted. The particles are now part of the plant’s geology. They are scattered and can be found at different layers in the crust. Mostly in deeper locations it can get closer to the surface at some point. Star metal, star dust anyone? Maybe we can find a cooler name than that: celestial metal?
Diameter: 19 270 km
Mass: 0,64 Sun
Density: 339 800 g/cm
Hill sphere: 10 AU ?
Temperature: 9498 °C
habitable zone between 5 and 7 m km
Distance form main star: 75 AU
Orbital period: 507 years
The 8 planets and the second star are known as the 9 wandering stars…
