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 on 18 May 1990, by American female astronomer Eleanor Helin at the U.S. Palomar Observatory in California. The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 1.04 kilometers, based on an absolute magnitude of 17.26. In the 1990s, Tom Gehrels estimated the body's diameter to be 2.3 kilometers, assuming an albedo of 0.15.
