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 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 .
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 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.

For millennia, what today is known to be the Solar System was regarded as the "whole universe", so the knowledge of both mostly advanced in parallel. A clear distinction was not made until around the mid-17th century. Since then, incremental knowledge has been gained not only about the Solar System, but also about outer space and its deep-sky ...
