Potentially Hazardous Asteroid
1620 Geographos (1951 RA) is classified as a Potentially Hazardous Asteroid (PHA) because it is estimated to be larger than 140 meters and its orbit comes within 0.05 AU of Earth. NASA continuously monitors this object for any future impact risk. Current data does not indicate a confirmed impact event.
Asteroid
1620 Geographos is a highly elongated, stony asteroid, near-Earth object and potentially hazardous asteroid of the Apollo group, with a mean diameter of approximately 2.5ย km (1.6ย mi). It was discovered on 14 September 1951, by astronomers Albert George Wilson and Rudolph Minkowski at the Palomar Observatory in California, United States. The asteroid was named in honor of the National Geographic Society.
