This is a timeline of Solar System exploration ordered by date of spacecraft launch. It includes:
It does not include:
The dates listed are launch dates, but the achievements noted may have occurred some time later—in some cases, a considerable time later (for example, Voyager 2, launched 20 August 1977, did not reach Neptune until 1989).
Missions in italics are unfinished, i.e. have not yet been designated as successes or failures. Some unitalicised missions are nevertheless still operational, some in mission extension phases.
