1508 Kemi (1938 UP) is a large Mars-crossing asteroid discovered on October 21, 1938, by H. Alikoski at Turku, and independently discovered on October 30, 1938, by György Kulin at Budapest.[3] At roughly 17 km in diameter,[2] it is one of the largest Mars-crossing asteroids. It has been grouped with the Pallas family because of its high inclination, similar to other objects in that family,[4] but has different spectral characteristics than many Pallas asteroids.[5] It is classified as a BCF-type asteroid.

It is named after the town of Kemi, in Finland, and the Kemi River, the largest river in Finland, on which the town lies, in keeping with a pattern of giving high-inclination asteroids four-letter names.[3]
