Which planets, moons, asteroids and comets have we actually reached, how, and when did we first get there? The table lists every body in our selection of notable missions, with the highest level of visit: a flyby, an orbit, a landing, or people on the surface. The Moon is the only body where people have landed.

How these numbers are counted
This is a selection of notable missions, not every spacecraft ever sent. The list of missions and the level of each visit (flyby, orbit, landing) are kept by hand from NASA, ESA, JAXA and other agency pages; launch dates come from Wikidata. “First” and “latest” mean the first and last mission in this list, by launch date, not necessarily the first or last mission to arrive. A body appears only once at its highest level, so Mars shows as landed even though most Mars missions are orbiters.
