    7959 Alysecherri, provisional designation 1994 PK, is a bright, stony Hungaria asteroid from the inner regions of the asteroid belt, approximately 3 kilometers in diameter. It was discovered on 2 August 1994, by American astronomer Carl Hergenrother at Steward Observatory's Catalina Station on Mt Bigelow near Tucson, Arizona. [6] The asteroid was named for the discoverer's wife, Alyse Cherri. [2]

    Orbit and classification

    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 in the inner main-belt at a distance of 1.8–2.1  AU once every 2 years and 9 months (989 days). Its orbit has an eccentricity of 0.09 and an inclination of 19° with respect to the ecliptic. [1] The first precovery was taken at Palomar Observatory in 1951, extending the asteroid's observation arc by 43 years prior to its discovery. [6]

    Physical characteristics

    A rotational lightcurve for this asteroid was obtained from photometric observations made by American astronomer Brian Warner at the U.S. Palmer Divide Observatory, Colorado, in July 2013. It gave a rotation period of 3.161±0.005 hours with a brightness amplitude of 0.13 in magnitude ( U=2 ). [4] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.30 and calculates a diameter of 3.05 kilometers with an absolute magnitude of 14.5. [3]

    Naming

    This minor planet is named after the maiden name of the discovering astronomer's wife, Alyse Cherri Smith. [2] The official naming citation was published by the Minor Planet Center on 13 November 2008 ( M.P.C. 64311). [7]
