It was discovered on 7 September 1995, by Slovak astronomers Adri\u00e1n Gal\u00e1d and Alexander Pravda at the Modra Observatory in the Bratislava Region of Slovakia.[9] The asteroid was named after Slovak amateur astronomer Peter Mrva.[2]       (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4Table of ContentsOrbit and classification[edit]Physical characteristics[edit]References[edit]External links[edit]Orbit and classification[edit]Petermrva is a member of the Flora family, one of the largest families of stony asteroids. It orbits the Sun in the inner main-belt at a distance of 1.8\u20132.6\u00a0AU once every 3 years and 3 months (1,200 days). Its orbit has an eccentricity of 0.17 and an inclination of 6\u00b0 with respect to the ecliptic.[1] The first precovery was taken at Crimea-Nauchnij in 1972, extending the asteroid&#8217;s observation arc by 23 years prior to its discovery.[9]Physical characteristics[edit]Two well-defined rotational lightcurves of Petermrva were obtained from photometric observations at the Modra and Ond\u0159ejov Observatory rendered a rotation period of 2.98502\u00b10.00004 and 2.9848\u00b10.0002 hours, with a brightness amplitude of 0.18 and 0.14 in magnitude, respectively (U=3\/3).[7][a]According to the thermal observation carried out by the NEOWISE mission of NASA&#8217;s Wide-field Infrared Survey Explorer, Petermrva measures 4.2 kilometer and has an untypically low albedo of 0.15.[4]       (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4This minor planet is named after Slovak amateur astronomer Peter Mrva (born 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.[2] The approved naming citation was published by the Minor Planet Center on 27 April 2002 (M.P.C. 45338).[10]References[edit]^ a b c d &#8220;JPL Small-Body Database Browser: 13154 Petermrva (1995 RC)&#8221; (2017-05-05 last obs.).
