(1877) Marsden is an asteroid of the main outer belt . On March 24, 1971, CJ van Houten and I. van Houten-Groeneveld discovered him at the University of Leiden on images of a 1.22 m Schmidt telescope made by T. Gehrels at the Mount Palomar Observatory in California as part of an investigation faint Trojans had been made. Subsequently, the asteroid could already be detected on recordings made in 1950 at the State Observatory in Heidelberg-Königstuhl and at the Goethe Link Observatory in Indiana , and in 1953 and 1955 also at the Mount Palomar Observatory.

As a member of the Hilda family (1877) Marsden belongs to a group of asteroids that orbit the sun in an orbital resonance of 3: 2 with the planet Jupiter .

The asteroid was named on June 1, 1975 after the American astronomer Brian Marsden (1937-2010) of the Smithsonian Astrophysical Observatory in Massachusetts , in recognition of his numerous contributions in the field of orbital computation of comets and asteroids, his revision of the Catalog of Cometary Orbits and its activities in the IAU . It was named at the suggestion of his colleagues Elizabeth Roemer , Frank K. Edmondson , Tom Gehrels and Paul Herget .
