    (15502) 1999 NV27 (provisional designation 1999 NV27) is a Jupiter trojan from the Trojan camp, approximately 53 kilometers (33 miles) in diameter. It was discovered on 14 July 1999, by astronomers with the Lincoln Near-Earth Asteroid Research at the Lincoln Lab's ETS near Socorro, New Mexico, in the United States. [1] The dark Jovian asteroid has a rotation period of 15.1 hours and belongs to the 90 largest Jupiter trojans. [8] It has not been named since its numbering in June 2000. [10]

    Orbit and classification

    1999 NV27 is a dark Jovian asteroid in a 1:1 orbital resonance with Jupiter. It is located in the trailering Trojan camp at the Gas Giant's L5 Lagrangian point, 60° behind its orbit (see Trojans in astronomy). [3] It is also a non-family asteroid of the Jovian background population. [4]

    It orbits the Sun at a distance of 5.0–5.2  AU once every 11 years and 7 months (4,238 days; semi-major axis of 5.12 AU). Its orbit has an eccentricity of 0.02 and an inclination of 17° with respect to the ecliptic. [2] The body's observation arc begins with its first observation as 1982 BX14 at Palomar Observatory in January 1982, more than 16 years prior to its official discovery observation at Socorro. [1]

    Numbering and naming

    This minor planet was numbered by the Minor Planet Center on 21 June 2000 ( M.P.C. 40827). [10] As of 2021, it has not been named. [1]

    Physical characteristics

    1999 NV27 is an assumed, carbonaceous C-type asteroid. [8] It has a V–I color index of 0.875. [9]

    Rotation period

    In September 2009, a first rotational lightcurve of 1999 NV27 was obtained from photometric observations by Linda French at the Cerro Tololo Inter-American Observatory in Chile. Lightcurve analysis gave a rotation period of 15.03±0.03 hours with a brightness variation of 0.10 magnitude ( U=2 ). [8] [11]

    Since then, follow-up observations by Daniel Coley and Robert Stephens at the Center for Solar System Studies during 2013–2017 gave four more refined lightcurves, with the best-rated one from January 2017 showing a rotation period of 15.129±0.002 hours and an amplitude of 0.26 magnitude ( U=3 ). [7] [12] [13] [14] [lower-alpha 1]

    Diameter and albedo

    According to the surveys carried out by the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, 1999 NV27 measures 50.86 and 53.10 kilometers in diameter and its surface has an albedo of 0.067 and 0.069, respectively. [5] [6] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for a carbonaceous asteroid of 0.057 and calculates a diameter of 55.67 kilometers based on an absolute magnitude of 10.0.
