1877 Marsden, provisional designation 1971 FC, is a carbonaceous asteroid from the outer region of the asteroid belt, about 35 kilometers in diameter. It was discovered by Cornelis van Houten and I. van Houten-Groeneveld at Leiden, on photographic plates taken by Tom Gehrels at Palomar Observatory, California on 24 March 1971.[7]
It is a member of the Hilda family of asteroids. It orbits the Sun at a distance of 3.1–4.8 AU once every 7 years and 10 months (2,855 days). It has a rotation period of 14.4 hours.[5] The albedo of the C-type asteroid is in the range of 0.06 to 0.08.[4][6]
It is named in honor of British astronomer Brian Geoffrey Marsden (1937–2010), director of the Minor Planet Center at the Harvard-Smithsonian Center for Astrophysics, in recognition of his numerous contributions in the field of orbit calculations for comets and minor planets.[2]
The discovery was made in a survey of faint Trojans. The trio of Dutch and Dutch–American astronomers also collaborated on the productive Palomar–Leiden survey in the 1960s, using the same procedure as for this (smaller) survey: Gehrels used Palomar's Samuel Oschin telescope (also known as the 48-inch Schmidt Telescope), and shipped the photographic plates to Cornelis and Ingrid van Houten at Leiden Observatory where astrometry was carried out.
