Geographos is a near-Earth object and a Mars-crosser asteroid. In 1994, during the asteroid's closest approach to Earth in two centuries, a radar study of it was conducted by the Deep Space Network at Goldstone, California. The resultant images show Geographos to be the most elongated object in the solar system; it measures 5.1x1.8 km.
