8013 Gordonmoore, provisional designation 1990 KA, is an eccentric, stony asteroid, classified as Amor asteroid and near-Earth object, roughly 1–2 kilometers in diameter. It was discovered by American female astronomer Eleanor Helin at the U.S. Palomar Observatory in California, on 18 May 1990.[5]
The S-type asteroid orbits the Sun at a distance of 1.2–3.1 AU once every 3 years and 3 months (1,191 days). Its orbit is tilted by 8 degrees to the plane of the ecliptic and shows a very high eccentricity of 0.43.[1] Photometric light-curve observation at the Hoher List Observatory, Germany, rendered an approximate rotation period of 6 hours with a brightness amplitude of 0.5 in magnitude.[4] The Collaborative Asteroid Lightcurve Link (CALL) assumes an albedo of 0.20, a typical value for asteroids with a stony surface composition.[3]
The asteroid is not considered a potentially hazardous object, as it never approaches Earth's orbit closer than 0.24 AU (also see Minimum orbit intersection distance, MOID). Due to its very eccentric orbit, it is also Mars-crossing asteroid, and in 2127, it will pass within 0.02776 AU (4,153,000 km) from the Red Planet.[1]
The minor planet was named in honour of American entrepreneur and billionaire, Gordon Moore (b. 1929), co-founder of Intel, renowned for his revolutionary vision of the future of computers, and author of Moore's law. He has been a lifelong contributor to and supporter of education, research and technology.[2]
