NASA, on Thursday, released an image of a comet that is expected to pass within 84,000 miles of Mars -- less than half the distance between Earth and the moon -- on Oct. 19, and the finding could help scientists determine potential hazards to spacecraft in the vicinity of the red planet. The average distance from Earth to the moon is about 238,855 miles.
