* <sup>†</sup> means "tentatively identified", as classified by NASA.<ref name=tentative>{{cite web|url=http://nssdc.gsfc.nasa.gov/planetary/tent_launch.html |title=Tentatively Identified Missions and Launch Failures |author=NSSDC |publisher=[[NASA]] |access-date=27 August 2016|author-link=NSSDC }}</ref> 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:
:* closest encounter (flybys)
:* impact (impactors)
:* orbital insertion to end of mission, whether planned or premature (orbiters)
:* landing to end of mission, whether planned or premature (landers)
:* launch (missions that never got underway due to failure at or soon after launch)
: In cases which do not fit any of the above, the event to which the date refers is stated. As a result of this scheme missions are not always listed in order of launch.

* Some of the terms used under '''Type''':
:* Flyby: The probe flies by an astronomical body, but does not orbit it
:* [[Orbiter]]: Part of a probe that orbits an astronomical body
:* [[Lander (spacecraft)|Lander]]: Part of a probe that descend to the surface of an astronomical body
:* [[Rover (space exploration)|Rover]]: Part of a probe that acts as a vehicle to move on the solid-surface of an astronomical body
:* Penetrator: Part of a probe that impacts an astronomical body
:* Atmospheric probe or balloon: Part of a probe that descend through or floats in the atmosphere of an astronomical body; not restricted to [[weather balloon]]s and other [[atmospheric sounder]]s, as it can also be used for surface and subsurface imaging and [[remote sensing]].
:* [[Sample return mission|Sample return]]: Parts of the probe return to Earth with physical samples

* Under '''Status''', in the case of flybys (such as gravity assists) that are incidental to the main mission, "success" indicates the successful completion of the flyby, not necessarily that of the main mission.
