1979 Sakharov, also designated 2006 P–L, is a stony vestian asteroid from the inner regions of the asteroid belt, about 5 kilometers in diameter. It was discovered by the Dutch astronomers Ingrid and Cornelis van Houten, on photographic plates taken by Dutch–American astronomer Tom Gehrels at the U.S. Palomar Observatory in California, on September 24, 1960.[8]
The S-type asteroid is a member of the Vesta family. It orbits the Sun at a distance of 2.1–2.6 AU once every 3.66 years (1336 days). It has a well-defined rotation period of seven and a half hours, determined by several photometric light-curve analysis.[6][7] The body's albedo has been determined by WISE and NEOWISE surveys and varies between 0.26 and 0.31.[4][5]
It is named in honour of a distinguished Russian mathematician and physicist Andrei Sakharov, who received the 1975 Nobel peace prize.[2]
The designation P–L stands for Palomar–Leiden, named after Palomar Observatory and Leiden Observatory, which collaborated on the fruitful Palomar–Leiden survey in the 1960s. Gehrels used Palomar's Samuel Oschin telescope (also known as the 48-inch Schmidt Telescope), and shipped the photographic plates to Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld at Leiden Observatory. The trio are credited with several thousand asteroid discoveries.
