Rules are simple: Everyone gets control of their own planet, which starts as a glowing ball of lava. Limit is 7 planets and when full, you have to join other's planets. Hope each one is different! Good luck!
Make meh planet! It drifts very far away from the sun, cooling it! It then freezes into an icy wastleland! A wandering astroid hits it, the shock makeing a not-so-icy area, and getting it a bit closer to the sun! The Asteriod splits into 2 moons which orbit it!
I make a planet called GJ 97852 B about 8.7 times more mass then Earth, 5.7 times the size and 4.8 times the gravitational force get smashed by tons of comets(they're icy) so the crust cools
[b]Then an asteroid about 0.889 the size of Earth hits this protoplanet which forms its two moons GJ 97852 Ba and Bb!!!!!!!![b]
however the force of the asteroid pushes it into a cold icy area where there is a stationary gigantic asteroid the size of jupiter and it and my planet become co-orbital planets!
The tidal heating of the other planets gravity forces volcanoes to spurt out Co2(carbon dioxide) hydrogen, methane, nitrogen and sulfur into the cloudy hazy atmosphere!
But the co2 goes into the soil which liquid methane/sulfur erodes away!
Equivalent to Earth:
Oxygen= Methane
Water= liquid Nitrogen
Water vapour= gassy nitrogen
Carbon Dioxide= 1/2 sulfur 1/2 hydrogen
you need to travel @ at least 49 km/s to get out of the gravitational influence!
It's moons cause tides and even tsunamis//of liquid nitrogen//
