– 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.
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
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.

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.
Since then, increasingly distant planets have been reached, with probes landing on or impacting the surfaces of Venus in 1966 , Mars in 1971 (Mars 3, although a fully successful landing didn't occur until Viking 1 in 1976), the asteroid Eros in 2001 (NEAR Shoemaker), Saturn's moon Titan in 2004 , the comets Tempel 1 (Deep Impact) in 2005, and ...
1946 – American launch of a camera-equipped V-2 rocket provides the first image of the Earth from space. [174] 1949 – Gerard Kuiper discovers Uranus's moon Miranda and Neptune's moon Nereid. [173] 1950 – Jan Oort suggests the presence of a cometary reservoir in the outer limits of the Solar System, the Oort cloud. [175]
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.
