1304 Arosa, provisional designation 1928 KC, is an outer main-belt asteroid discovered on May 21, 1928, by Karl Reinmuth at Heidelberg Observatory, Germany.[1]
The X-type asteroid has a high albedo of 0.35 and measures about 43 kilometers in diameter.[4] Inclined by 19 degrees to the ecliptic, it orbits the Sun at a distance of 2.8–3.6 AU once every 5.73 years.[2] Its rotational period is close to 7 hours and 45 minutes.[5]
The asteroid is named after the town Arosa, a summer and a winter tourist resort in the Swiss Alps.[3]
