Number of minor planets and comets visited by spacecraft

The following tables list all minor planets and comets that have been visited by robotic spacecraft.

قائمة الكواكب الصغرى التي زارتها مركبات فضائية

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).

Spacecraft visited by comets

Comet C/2013 A1 passed close by planet Mars in October 2014, closer than the Moon is to Earth.[19] As of early 2014 it was calculated to pass as close as 0.00087 AU (130،000 km; 81،000 mi).[19] This was so close that the event was deemed dangerous to spacecraft in orbit around Mars.[20] Spacecraft that were active at that time included 2001 Mars Odyssey, Mars Express, MAVEN, Mars Orbiter Mission, and Mars Reconnaissance Orbiter in Mars orbit – and two on the surface – Mars Exploration Rover Opportunity and the Mars Science Laboratory Curiosity.
