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, but excludes lunar missions, which are listed separately at List of lunar probes and List of Apollo missions. Flybys that were incidental to the main purpose of the mission are also included. Flybys of Earth are listed separately at List of Earth flybys. Confirmed future probes are included, but missions that are still at the concept stage, or which never progressed beyond the concept stage, are not.
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.

Probes leaving the Solar System
Spacecraft | Organization | Notes | Image | Ref |
Pioneer 10 | NASA | Left Jupiter in December 1973. Mission ended March 1997. Last contact 23 January 2003. Craft now presumed dead; no further contact attempts planned. | ||
Pioneer 11 | NASA | Left Saturn in September 1979. Last contact September 1995. The craft's antenna cannot be maneuvered to point to Earth, and it is not known if it is still transmitting. No further contact attempts are planned. | ||
Voyager 1 | NASA | Left Saturn in November 1980. Still in regular contact and transmitting scientific data. | ||
Voyager 2 | NASA | Left Neptune in August 1989. Still in regular contact and transmitting scientific data. | ||
New Horizons | NASA | Left Pluto 14 July 2015; flew by Kuiper belt object on 1 January 2019 when it was 43.4 AU from the Sun. | ||
IHP-1 | CNSA | Proposed Interstellar Heliosphere Probe with a 2024 launch date. Anticipated to reach a distance of at least 85 AU from Earth by 2049 | ||
IHP-2 | CNSA | Proposed Interstellar Heliosphere Probe with a 2024 launch date. Anticipated to reach a distance of at least 83 AU from Earth by 2049 |
