List of Solar System probes
This is a list of space probes that have left Earth orbit, organized by their planned destination. It includes planetary probes, solar probes, and probes to asteroids and comets. Flybys that were incidental to the main purpose of the mission are also included.
Excluded are lunar missions, which are listed separately at List of lunar probes and List of Apollo missions. Flybys of Earth are listed separately at List of Earth flybys. Planned and proposed missions are in the List of proposed Solar System probes.
Key
Colour key:- † means "tentatively identified", as classified by NASA. These are Cold War-era Soviet missions, mostly failures, about which few or no details have been officially released. The information given may be speculative.
- Date is the date of:
- Some of the terms used under Type:
- Under Status, in the case of flybys that are incidental to the main mission, "success" indicates the successful completion of the flyby, not necessarily that of the main mission.
