List of minor planets and comets visited by spacecraft

The following tables list all minor planets and comets that have been visited by robotic spacecraft. Orbited - when the spacecraft orbited the minor planet or comet Flyby - when the spacecraft approached within reasonable distance (~10,000 km) of the minor planet or comet Distant flyby - when it was further than the flyby distance Landed - when a landing was done on the minor planet or comet

List of minor planets visited by spacecraft

A total of 19 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, three asteroids have been imaged by spacecraft at distances too large to resolve features (over 100,000 km).
