Would just like to point out that gravity is not the deciding factor in a planetoid holding an atmosphere. It must have a magnetosphere (a magnetic field generated by a rotating liquid core) in order to protect against solar wind which will strip a planet of its atmosphere, literally blowing it away into space.
Mars is a case in point. Its large enough gravity wise to hold an atmosphere (bigger than Titan which holds a very thick atmosphere) but has a weak/virtually non-existent magnetosphere, as its dynamo liquid core stopped working billions of years ago. Since then its atmosphere was eroded by the solar wind. To the point where it is today, in that water could not exist as a liquid on the martian surface (even if the temp was right).
(NASA has a good article on this. If I can find it, I'll post a link).
So if Cybertron is to have an atmosphere (which is a requirement in order to have a free standing body of liquid), it must be protected by some sort of magnetic field. Possibly an "organic" molten core left over from the planetoid that Primus originally transformed (aka terraformed) into a mechanical world?
