Spacecraft visited by comets
[edit]Comet C/2013 A1 passed close by planet Mars in October 2014, closer than the Moon is to Earth.[14] As of early 2014 it was calculated to pass as close as 0.00087 AU (130,000 km; 81,000 mi).[14] This was so close that the event was deemed dangerous to spacecraft in orbit around Mars.[15] 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.
