Too far out from the sun and it wouldn't be able to re-charge using solar panels. Could put some kind of nuclear power plant on it though. And as others has pointed out, you would need to match the speed, so you could just as well use that power plus gravity assists to get far out. Landing on such a body would be really interesting though.

Probably the reason to orbit such a planet would be to help comms from a ground station on it.

11 AU though seems like quite the stretch right now but maybe if there were a fleet of Spacex Starships in operation…
