2013 Tucapel, provisional designation 1971 UH4, is a stony and eccentric asteroid from the inner regions of the asteroid belt, about 12 kilometers in diameter. It was discovered by Carlos Torres on exposures taken by J. Petit at the University of Chile's Cerro El Roble Astronomical Station on 22 October 1971.[8]

The S-type asteroid orbits the Sun at a distance of 1.8–2.8 AU once every three and a half years (1,265 days). Its orbit shows an eccentricity of 0.23 and is tilted by 8 degrees to the plane of the ecliptic. It has a rotation period of 9.028 hours and an albedo in the range of 0.11–0.32, according to the surveys carried out by Akari and WISE/NEOWISE.[4][5][6]

Named for one of the brave chiefs of the Mapuche, indigenous inhabitants of south-central Chile and southwestern Argentina, who, with his wife Gualeva, victoriously entered the city of Imperial. He died in 1560, fighting against the colonial Spaniards (also see Arauco War, Battle of Tucapel and Lautaro).[2]
