This is a list of all space probes that have left Earth orbit (or were
launched with that intention but failed), organised by their planned
destination. It includes planetary probes, solar probes, and probes to asteroids
and comets, but excludes lunar probes (listed separately at List
of lunar probes). Flybys (such as gravity
assists) that were incidental to the main purpose of the mission
are also included. Confirmed future probes are included, but missions that are
still at the concept stage, or which never progressed beyond the concept stage,
are not.
