The following tables list all minor planets and comets that have been visited by robotic spacecraft.
List of minor planets visited by spacecraft
A total of 17 minor planets (asteroids, dwarf planets, and Kuiper belt objects) have been visited by space probes. Moons (not directly orbiting the Sun) and planets are not minor planets and thus are not included in the table below.
Incidental flybys
In addition to the above listed objects, four asteroids have been imaged by spacecraft at distances too large to resolve features (over 100,000 km), and are labeled as such.
