    3642 Frieden, provisional designation 1953 XL1, is a carbonaceous asteroid from the outer region of the asteroid belt, approximately 35 kilometers in diameter. It was discovered by German astronomer Herta Gessner at Sonneberg Observatory on 4 December 1953.[10]

    The C-type asteroid orbits the Sun at a distance of 2.6–3.0 AU once every 4 years and 8 months (1,699 days). Its orbit has an eccentricity of 0.08 and an inclination of 13° with respect to the ecliptic.[1] The body was first identified as "1908 ED" at the U.S Taunton Observatory (803) in 1908, while its first used observation was made at the Belgian Uccle Observatory 1936, extending the asteroid's observation arc by 17 years prior to its official discovery.[10]

    According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid measures between 31.9 and 36.0 kilometers in diameter and its surface has an albedo between 0.046 and 0.071.[4][5][6][7] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.047 and a diameter of 35.1 kilometers, based on an absolute magnitude of 11.2.[3]

    In April 2006, a rotational light-curve was obtained for this asteroid from photometric observations by Brian D. Warner at his Palmer Divide Observatory, Colorado. It gave a well-defined rotation period of 14.491±0.003 hours with a brightness variation of 0.13±0.02 in magnitude (U=3).[8]

    The minor planet was named after the German translation of the goddess Pax in the hope for peace (German: Frieden) around the world.[2] Naming citation was published on 2 February 1988 (M.P.C. 12808).[11]
