    5951 Alicemonet, provisional designation 1986 TZ1, is a stony Flora asteroid approximately 6 kilometres in diameter from the inner regions of the asteroid belt. It was discovered on 7 October 1986, by American astronomer Edward Bowell at Anderson Mesa Station of the Lowell Observatory in Flagstaff, Arizona. [8] The asteroid was named after American astronomer Alice Monet. [2]

    Orbit and classification

    Alicemonet is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun in the inner main-belt at a distance of 1.7–2.7  AU once every 3 years and 3 months (1,190 days). Its orbit has an eccentricity of 0.22 and an inclination of 5° with respect to the ecliptic. [1]

    A first precovery was obtained at Palomar Observatory in 1952, extending the body's observation arc by 34 years prior to its official discovery observation at Anderson Mesa. [8]

    Physical characteristics

    Lightcurves

    In September 2012, a rotational lightcurve of Alicemonet was obtained using the SARA telescope at Cerro Tololo, Chile. [6] The photometric observations gave a well-defined rotation period of 3.8871 hours with a brightness variation of 0.46 magnitude ( U=3 ). [6]

    Diameter and albedo

    According to the survey carried out by the NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer, Alicemonet measures between 5.89 and 5.99 kilometers in diameter and its surface has an albedo of 0.284 and 0.293, respectively. [4] [5]

    The Collaborative Asteroid Lightcurve Link assumes a stony albedo of 0.24 – derived from 8 Flora, the largest member and namesake of this orbital family – and calculates a diameter of 5.9 kilometers with an absolute magnitude of 13.3. [3]

    Naming

    This minor planet was named after American astronomer Alice K. B. Monet (born 1954) at the United States Naval Observatory Flagstaff Station and former chair of the Division on Dynamical Astronomy of the AAS. She contributed to the NEAR Shoemaker and Galileo Mission and is known for her numerous astrometric observations. [2] The approved naming citation was published by the Minor Planet Center on 1 July 1996 ( M.P.C. 27460). [9]
