5951 Alicemonet, provisional designation 1986 TZ1, is a stony Flora asteroid from the inner regions of the asteroid belt, approximately 6 kilometers in diameter. It was discovered on 7 October 1986, by American astronomer Edward Bowell at Anderson Mesa Station of the U.S. Lowell Observatory in Flagstaff, Arizona.[7]
The S-type asteroid is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun at a distance of 1.7–2.7 AU once every 3 years and 3 months (1,190 days). Its orbit is tilted by 5° to the plane of the ecliptic and shows a notable eccentricity of 0.22.[1] The first precovery was obtained at Palomar Observatory in 1952, extending the asteroid's observation arc by 34 years prior to its discovery.[7]
In September 2012, a rotational light-curve was obtained using the SARA telescope at Cerro Tololo, Chile.[5] The photometric observations rendered a well-defined rotation period of 3.8871±0.0005 hours with a brightness variation of 0.46 in magnitude (U=3).[5] According to the survey carried out by the NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer, the asteroid measures 6.0 kilometers in diameter and its surface has an albedo of 0.28,[4] while the Collaborative Asteroid Lightcurve Link assumes an 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, based on an absolute magnitude of 13.3.[3]
The minor planet was named after American female astronomer Alice K.B. Monet (b. 1954, née Babcock) 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] Naming citation was first published on 1 July 1996 (M.P.C. 27460).[8]
