1479 Inkeri (1938 DE) is a main-belt asteroid discovered on February 16, 1938, by Vaisala, Y. at Turku. Its 660-hour rotation period is unusually long.^[2]

"Inkeri" is a Finnish female name, held by two of Vaisala's younger relatives. It is also the Finnish name of Ingria, a formerly-Finnish province near Saint Petersburg that is now part of Russia.^[3]
