Physical characteristics

2024 McLaughlin, provisional designation 1952 UR, is an asteroid from the inner regions of the asteroid belt. It was discovered 23 October 23, 1952 by Indiana Asteroid Program at U.S Goethe Link Observatory near Brooklyn, Indiana.[3]

The asteroid orbits the Sun at a distance of 2.0–2.6 AU once every three and a half years (1,295 days). Its orbit shows an eccentricity of 0.14 and is tilted by 7 degrees to the ecliptic plane. Little is known about the asteroids size, composition, albedo and rotation, despite having a well-observed orbit with the lowest possible uncertainty (i.e. a condition code of 0) and an observation arc that spans over a time period of more than 75 years.[1]

It is named in memory of American astronomer and geologist Dean Benjamin McLaughlin (1901–1965) at Swarthmore College and the University of Michigan. As an astronomical spectroscopist he was the first to rigorously measure stellar rotation, notably the one of Algol. As a geologist he was one of the first to interpret the telescopically observable markings on Mars, which were later confirmed by direct observations from spacecraft (also see Albedo features).[2] The lunar and Martian crater McLaughlin are also named in his honour.
