High Quality Content by WIKIPEDIA articles! The asteroid 1620 Geographos was discovered on September 14, 1951 at the Palomar Observatory by Albert Wilson and Rudolph Minkowski. It was originally given the provisional designation 1951 RA. Its name is attributed to the Greek word which means "geographer", and was chosen to honour the National Geographic Society, and Geographers. Geographos is a Mars-crosser asteroid and a near-Earth object belonging to the Apollos. In 1994, during the asteroid's closest approach to Earth in two centuries at 5.0 Gm-which will not be bettered until 2586- 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.
