This computer mosaic of Deimos was made with images acquired from the Viking Orbiter during one of its close approaches to the moon. The 15 km diameter Deimos circles Mars every 30 hours. Scientists speculate that Deimos and its companion moon Phobos were once passing asteroids that were pulled in by the gravity of Mars.
