100268 Rosenthal, provisional designation 1994 TL16, is an asteroid from the inner regions of the asteroid belt, roughly 3 kilometers in diameter. It was discovered by German astronomer Freimut Börngen at the Karl Schwarzschild Observatory, Thuringia, on 5 October 1994.[4]
The asteroid orbits the Sun at a distance of 2.0–2.9 AU once every 3 years and 10 months (1,392 days). Its orbit shows an eccentricity of 0.17 and is tilted by 12 degrees to the plane of the ecliptic. 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 period of several decades.[1]
Based on its absolute magnitude of 15.6, its diameter could be anywhere between 2 and 5 kilometers, assuming an albedo in the range of 0.05 to 0.25.[3] Since asteroids in the inner main-belt are often of a brighter silicaceous – rather than of a darker carbonaceous composition, with higher albedos, typically around 0.20, the asteroid's diameter might be on the lower end of NASA's published conversion table, as the lower the reflectivity (albedo), the larger the body's diameter for a given absolute magnitude.[3]
The minor planet was named in honour of famous German radio and TV host Hans Rosenthal (1925–1987), a German Jew who survived the Holocaust as a boy inside Germany and became one of the country's most popular TV show masters ever in the early 1980s. He died of cancer at the age of 61.[2]
