# How accurate can a satellite's orbit be?

How precise can an artificial satellite be when it comes to following the exact orbit in relation to Earth or hitting the same point above Earth in orbit? Which orbit would be the most stable for this?

• What exactly is a "mark in orbit"? Space has a rather noticeable lack of landmarks. In practice, orbits are indeed Earth-relative. – MSalters Oct 16 '18 at 9:16
