That's a fair point. So then one might expect the ghost to continue their motion tangential to the orbit of the earth, and so they'll float away.

However, the theory of general relativity suggests that gravity isn't really like other forces. It doesn't push or pull anything at all; but rather its bends the fabric of time and space. Objects 'falling' due to gravity, or 'in orbit' around a planet are actually moving in a direct straight line in curved space-time. And this is why gravity still applies to massless objects such as light. So then, I'd say the ghost would still be affected by gravity - and that their main concern would be falling into the earth rather than drifting away.
