13154 Petermrva

13154 Petermrva, provisional designation 1995 RC, is a stony Flora asteroid from the inner regions of the asteroid belt, approximately 4.2 kilometers in diameter. It was discovered on 7 September 1995, by Slovak astronomers Adrián Galád and Alexander Pravda at the Modra Observatory in the Bratislava Region of Slovakia.

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 1.8–2.6 AU once every 3 years and 3 months (1,200 days). Its orbit has an eccentricity of 0.17 and an inclination of 6° with respect to the ecliptic. The first precovery was taken at Crimea-Nauchnij in 1972, extending the asteroid's observation arc by 23 years prior to its discovery.

Two well-defined photometric light-curve analysis at the Modra and Ondřejov Observatory rendered a rotation period of 7000298502000000000♠2.98502±0.00004 and 7000298480000000000♠2.9848±0.0002 hours, with a brightness amplitude of 0.18 and 0.14 in magnitude, respectively (U=3/3). According to the thermal observation carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid measures 4.2 kilometer and has an untypically low albedo of 0.15.

The minor planet is named after Czech amateur astronomer Peter Mrva (b. 1962) who participated in the construction the discovering Modra Observatory, after which the minor planet 11118 Modra is named. He was also one of the first observers at the newly installed observatory. The second discoverer, Alexander Pravda, is thankful for his explanation and inspiration in some fields of astronomy and computer graphics. Naming citation was published on 27 April 2002 (M.P.C. 45338).
