Ceres

The asteroid Ceres was discovered by Boba Fett after teleporting to the Solar System. He was teleported by reactivating Project G.A.L.A.X.Y. Several skirmishes ocurred in the Asteroid belt containing Ceres between Rebels and TIE Fighters. The system was very useful to both the Empire and the Alliance; it was a hide-out to each. Also, Mars was a great place to set up a base, as it was protected by the dangerous asteroid field.

The CIS initially ignored Ceres, believing it to be too dangerous.
