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 first flying probe on in Solar System was the Vega balloons in 1985, while first powered flight was undertook by Ingenuity in 2020. The only crewed rover to visit another world was NASA's Lunar Roving Vehicle , which traveled with Apollos 15 , 16 and 17 between 1971 and 1972.
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 .

Solar system diagram by Emanuel Bowen in 1747, when neither Uranus, Neptune, nor the asteroid belts had yet been discovered. Orbits of planets are to scale, but the orbits of moons and the sizes of bodies are not. The term "Solar System" entered the English language by 1704, when John Locke used it to refer to the Sun, planets, and comets. [290]
first probe to cross the asteroid belt; first Jupiter probe; first man-made object on an interstellar trajectory; now in the outer regions of the Solar System but no longer contactable 1972-012A: Pioneer 11: NASA: 4 December 1974 flyby success went on to visit Saturn 1973-019A: Voyager 1: NASA: 5 March 1979 flyby success went on to visit Saturn ...
Pluto's reign. For decades, students learned the phrase "My Very Educated Mother Just Served Us Nine Pizzas" to remember the order of the planets in the solar system: Mercury, Venus, Earth, Mars ...
Within it lies the Solar System. 1930 – Clyde Tombaugh discovers Pluto. [163] 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. [164]
