Timeline of Solar System exploration

This article is about listing events in a comprehensive list. For a timeline of first-ever achievements, see Timeline of space exploration.
Charted timeline of Solar System exploration, as of December 2014

This is a timeline of Solar System exploration ordering events in the exploration of the Solar System by date of spacecraft launch. It includes:

  • All spacecraft that have left Earth orbit for the purposes of Solar System exploration (or were launched with that intention but failed), including lunar probes.
  • A small number of pioneering or notable Earth-orbiting craft.[vague]

It does not include:

  • Centuries of terrestrial telescopic observation.
  • The great majority of Earth-orbiting satellites.
  • Space probes leaving Earth orbit that are not concerned with Solar System exploration (such as space telescopes targeted at distant galaxies, cosmic background radiation observatories, and so on).
  • Probes that failed at launch.

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).
