== List of minor planets visited by spacecraft ==
Since the 1990s, a total of 13 minor planets – currently all of them are asteroids and dwarf planets – have been visited by space probes. Note that moons (not directly orbiting the Sun), comets and planets are not minor planets and thus are not included in the table below.
In addition to the listed objects, three asteroids have been imaged by spacecraft at distances too large to resolve features (over 100,000 km), and are hence not considered as "visited". Asteroid 132524 APL was imaged by ''New Horizons'' in 2006 at a distance of 101,867 km, 2685 Masursky by ''Cassini'' in 2000 at a distance of 1,600,000 km, and 307 Nike by Pioneer 10 in 1972 at a distance of 8,800,000 km. The Hubble Space Telescope, a spacecraft in Earth orbit, has imaged several large asteroids, including 2 Pallas and 3 Juno.
