(16070) 1999 RB101, provisional designation 1999 RB101, is a Jupiter trojan from the Trojan camp, approximately 64 kilometers (40 miles) 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.[3]
Orbit and classification
1999 RB101 is located in the L5 Lagrangian point, 60° behind Jupiter in the so-called Trojan camp.[4] It is also a non-family asteroid of the Jovian background population.[5] 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.[2]
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, 1999 RB101 is a dark D-type asteroid.[15][13] 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.[3]
Rotation period
Several rotational lightcurves of 1999 RB101 have been obtained from photometric observations by Daniel Coley and Robert Stephens at GMARS (G79) and the Center for Solar System Studies, California. Analysis of the best-rated lightcurve from October 2011 gave a rotation period of ±0.01 hours with a brightness variation of 20.24±0.01 0.10magnitude (U=2).[3][9][10][11][lower-alpha 1] A longer period with a high amplitude reported by Duffard Melita has received a lower rating (U=2-).[lower-alpha 2]
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, 1999 RB101 measures between 63.19 and 68.98 kilometers in diameter and its surface has an albedo between 0.045 and 0.058.[6][7][8] CALL derives an albedo of 0.0565 and a diameter of 64.19 kilometers based on an absolute magnitude of 9.7.[3]
