Using Artefaxian's excellent spreadsheet I have created a basic idea for my planet, but in the 'Stability Checker' part my low gravity planet is unable to hold H2O.
I am wondering if it is possible to have a planet with low gravity and water vapour.
Mars apparently still has water vapour so I think it must be more than just escape velocity affecting the composition of the atmosphere.
EDIT: I'm wanting a planet with low gravity and oceans, rivers and lakes. Is this feasible or is it only possible to have traces of water on a planet with low gravity?
