– Unsuccessful soft landing, intentional hard landing, or mission still in progress. – Successful soft landing with intelligible data return. The tannish hue indicates extraterrestrial soil. – Successful soft landing, intelligible data return, and sample return to Earth. The greenish hue indicates terrestrial return.
Montage of planets and some moons that the two Voyager spacecraft have visited and studied. It is the only program that visited all four outer planets. A total of nine spacecraft have been launched on missions that involve visits to the outer planets; all nine missions involve encounters with Jupiter, with four spacecraft also visiting Saturn.

This is a list of space probes that have left Earth orbit (or were launched with that intention but failed), 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.

In many cases it is not possible to have an exact value, and an estimated range is instead provided. The coldest and oldest planet directly imaged is Epsilon Indi Ab, which has six times Jupiter's mass, an effective temperature of 275 K, and an age of about 3.5 Ga. This list includes the four members of the multi-planet system that orbit HR 8799.

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.
