3851 Alhambra, provisional designation 1986 UZ, is a stony asteroid from the inner regions of the asteroid belt, about 7 kilometers in diameter. It was discovered on 30 October 1986, by Japanese astronomer Tsutomu Seki at Geisei Observatory in Kōchi, Japan.[2]
The S-type asteroid is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun at a distance of 2.0–2.3 AU once every 3 years and 3 months (1,171 days). Its orbit shows an eccentricity of 0.06 and is tilted by 5 degrees to the plane of the ecliptic. Photometric light-curve observations made in 2007 at the Hunters Hill Observatory at Ngunnawal, Australia, rendered a relatively long rotation period of 53 hours with a brightness amplitude of 0.43 in magnitude.[5] The body has a albedo of 0.24, according to the space-based NEOWISE mission of the Wide-field Infrared Survey Explorer.[4]
The minor planet was named for Alhambra ("the red one"), the famous medieval palace and fortress complex of the Moorish emirs, located in Granada, Andalusia, Spain. The place with its islamic architecture is now a UNESCO World Heritage Site and one of Spain's major tourist attractions. The great guitarist Andrés Segovia frequently included "Memory of Alhambra" in his performances.[2]
