1832 Mrkos, provisional designation 1969 PC, is a carbonaceous asteroid from the outer region of the asteroid belt, about 30 kilometers in diameter. It was discovered by Lyudmila Chernykh at the Crimean Astrophysical Observatory in Nauchnyj on 11 August 1969.[8]
It orbits the Sun at a distance of 2.9–3.6 AU once every 5 years and 9 months (2,106 days). The C-type asteroid has an albedo of 0.074 as measured by the Infrared Astronomical Satellite, IRAS, while observation by Akari and NEOWISE gave 0.097 and 0.068, respectively. It takes 13.6 hours to rotate around its axis.[7]
The asteroid was named in honor of Czech astronomer Antonín Mrkos (1918–1996), a prolific discoverer of 273 minor planets and well known for his contributions to cometary astronomy. He was the director of the Kleť Observatory in what is now the Czech Republic, initiated the first minor planet survey in his country, was a professor at Charles University in Prague and University of South Bohemia, and a participant of a Soviet Antarctic expedition in the late 1950s.[2]
