So on the KSP Wiki the definition of sub-orbital claims that a craft in sub-orbital orbit will eventually "collide with the body being orbited". That being said I've had a craft in sub-orbit for the past 13 days (In-game) but I've noticed no decrease in its orbit that would indicate it's orbit is decaying, which is what the wiki is suggesting imo. It could be that it just takes a lot longer than 13 days for this to become noticeable. Anyway my question is: Is the wiki correct and if so how long would it take for (very roughly) my craft to "collide" with the planet? If it helps my craft is orbiting Kerbin, has a Periapsis of 66.077m and a Apoapsis of 559,665m. Apologizes if this has been asked before, I tried a few searches but couldn't find anything related.
