Here is a brief detail on the planet i created. Mass .218 earths, density 5.62 g/cm3, radius .60 earths, surface gravity is .602 earths It has 1 moon that has 5% the mass of the main world orbiting 300,000 miles above the surface. It orbits a sun like star, same luminosity and mass every 342 days, eccentricity is .08 The average temperature is 305 Kelvin It has 80% water and 20% land, the crust ranges from 5-30 miles thick I am just wondering if this planet can support a thick atmosphere of carbon dioxide, nitrogen, oxygen, water vapor and some methane. I also need to know if the planet an generate a magnetic field. The planet i created is currently 3.5 billion years old and it is in a stable solar system that is 50 light years from earth.
