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 .
Within it lies the Solar System. 1930 – Clyde Tombaugh discovers Pluto. [166] It was regarded for decades as the ninth planet of the Solar System. The first photo from space was taken from a V-2 launched by US scientists on 24 October 1946. 1930 – Seth Nicholson and Edison Pettit measure the surface temperature of the Moon. [167]
This is a timeline of space exploration which includes notable achievements, first accomplishments and milestones in humanity's exploration of outer space. This timeline generally does not distinguish achievements by a specific country or private company, as it considers humanity as a whole.
The Hubble Space Telescope, the first large optical telescope in orbit, is launched using the Space Shuttle, but astronomers soon discovered that it is crippled by a problem with its mirror. A complex repair mission in 1993 allows the telescope to start producing spectacular images of distant stars, nebulae, and galaxies.
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 ...
This is the boundary of the Solar System to interstellar space. The outermost region of the Solar System is the theorized Oort cloud, the source for long-period comets, extending to a radius of 2,000–200,000 AU. The closest star to the Solar System, Proxima Centauri, is 4.25 light-years (269,000 AU) away.

This is a comprehensive list of interplanetary spaceflights, spaceflight between two or more bodies of the Solar System, listed in chronological order by launch date.It includes only flights that escaped Earth orbit and reached the vicinity of another planet, asteroid, or comet.
