}}{{mp|(16070) 1999 RB|101}}, provisional designation {{mp|1999 RB|101}}, is a Jupiter trojan from the Trojan camp, approximately {{convert|64|km|mi|abbr=off|sigfig=2|sp=us}} in diameter. It was discovered on 8 September 1999, by astronomers with Lincoln Near-Earth Asteroid Research at Lincoln Laboratory's Experimental Test Site near Socorro, New Mexico, in the United States.[1] The dark D-type asteroid belongs to the 60 largest Jupiter trojans and has a rotation period of 20.24 hours.[5]

Orbit and classification

{{mp|1999 RB|101}} is located in the {{L5}} Lagrangian point, 60° behind Jupiter in the so-called Trojan camp.[6] It is also a non-family asteroid of the Jovian background population.[7] It orbits the Sun at a distance of 4.5–5.8 AU once every 11 years and 8 months (4,247 days; semi-major axis of 5.13 AU). Its orbit has an eccentricity of 0.12 and an inclination of 16° with respect to the ecliptic.

The body's observation arc begins with a precovery published by the Digitized Sky Survey and taken at the Palomar Observatory in September 1954, or 45 years prior to its official discovery observation at Socorro.[1]

Physical characteristics

In the SDSS-based taxonomy, {{mp|1999 RB|101}} is a dark D-type asteroid.[40][23] It has also been characterized as a D-type by Pan-STARRS' survey, while the Collaborative Asteroid Lightcurve Link (CALL) assumes it to be a C-type asteroid.[5]

Rotation period

Several rotational lightcurves of {{mp|1999 RB|101}} have been obtained from photometric observations by Daniel Coley and Robert Stephens at GMARS {{Obscode|G79}} and the Center for Solar System Studies, California. Analysis of the best-rated lightcurve from October 2011 gave a rotation period of {{val|20.24|0.01}} hours with a brightness variation of {{val|0.10|0.01}} magnitude ({{small|U=2}}).[5][14][15][17]{{efn|name=lightcurve-plots-CS3}} A longer period with a high amplitude reported by Duffard Melita has received a lower rating ({{small|U=2-}}).{{efn |name=LCDB-Melita-2012}}

Diameter and albedo

According to the surveys carried out by the Japanese Akari satellite, the Infrared Astronomical Satellite IRAS, and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, {{mp|1999 RB|101}} measures between 63.19 and 68.98 kilometers in diameter and its surface has an albedo between 0.045 and 0.058.[10][11][13] CALL derives an albedo of 0.0565 and a diameter of 64.19 kilometers based on an absolute magnitude of 9.7.[5]

{{Largest Jupiter trojans}}

Numbering and naming

This minor planet was numbered on 26 July 2000 ({{small|M.P.C. 40995}}).[51] As of 2018, it has not been named.[1]
