This is a timeline of Solar System exploration ordering events in the exploration of the Solar System by date of spacecraft launch. It includes: 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 .
In order to leave the Solar System, the probe needs to reach the local escape velocity. Escape velocity from the sun without the influence of Earth is 42.1 km/s. In order to reach this speed, it is highly advantageous to use as a boost the orbital speed of the Earth around the Sun, which is 29.78 km/s.
True-scale Solar System poster made by Emanuel Bowen in 1747. At that time, Uranus, Neptune, nor the asteroid belts had been discovered yet. Discovery and exploration of the Solar System is observation, visitation, and increase in knowledge and understanding of Earth's "cosmic neighborhood". [1]

A rover is a planetary surface exploration vehicle designed to move over the rough surface of a planet or other celestial body. Rovers are used to explore, collect information, and take samples of the surface. This is a list of all rovers on extraterrestrial bodies in the Solar System.
2 March 1972: Atlas SLV-3C Centaur-D Star-37E: NASA: Unnamed asteroid [3] Flyby — 307 Nike — Distant incidental flybys en route to Jupiter; closest approaches occurred on 2 August 1972 and 2 December 1972, respectively, with a distance of 8.8 million km (5.5 million mi). – Galileo project: Galileo: 18 October 1989: Space Shuttle Atlantis ...
Solar System belts are asteroid and comet belts that orbit the Sun in the Solar System in interplanetary space. [1] [2] The Solar System belts' size and placement are mostly a result of the Solar System having four giant planets: Jupiter, Saturn, Uranus and Neptune far from the sun. The giant planets must be in the correct place, not too close ...
