702 Alauda /əˈlɔːdə/, provisional designation 1910 KQ, is a carbonaceous asteroid and binary system from the outer asteroid belt, approximately 190 kilometers in diameter.[2] It is the parent body of the Alauda family. Discovered in 1910 by German astronomer Joseph Helffrich at Heidelberg Observatory, it was named after the lark (alauda).[3][6] Its small moon, named Pichi üñëm, was discovered in 2007.[10][21]
