7959 Alysecherri, provisional designation 1994 PK, is a bright, stony asteroid from the inner regions of the asteroid belt, about 3 kilometers in diameter. It was discovered by American astronomer Carl Hergenrother at the U.S. Catalina Station in Tucson, Arizona, during the Catalina Sky Survey on 2 August 1994.[5]
The E-type asteroid is a member of the Hungaria family, which form the innermost dense concentration of asteroids in the Solar System. It orbits the Sun at a distance of 1.8–2.1 AU once every 2 years and 9 months (989 days). Its orbit is tilted by 19 degrees to the plane of the ecliptic and shows an eccentricity of 0.09. Based on light-curve observations performed at the U.S. Palmer Divide Station in Colorado in 2013, the body has a rotation period of 3.161 hours and an assumed albedo of 0.30.[4]
The minor planet is named after the maiden name of Alyse Cherri Smith, wife of the discovering astronomer Carl Hegenrother. She worked for the Arizona state to prevent the abuse and neglect of Arizona's children.[2]
