Extract from newly published paper called “Observation and analysis of newly discovered Orbital Decay phenomenon“:
For optimum orbital lifetime a vessel should be beyond 2x the radius of the body it is orbiting, have a high mass and have a low surface area; or have plenty of station keeping fuel! Close orbits around the Sun or a dense atmospheric planet will have the shortest lifespan whereas orbits beyond Jupiter/Jool will likely last in excess of 50000 years.
Every controllable vessel has the ability to station keep, if the vessel has an ignited engine or RCS block and enough fuel. Once activated the fuel will drain based on the current decay rate and efficiency of the engines, station keeping will automatically be disabled if the station keeping fuel runs out.
