2201 Oljato, provisional designation 1947 XC, is stony and extremely eccentric asteroid, classified as near-Earth object. It measures approximately 2 kilometers in diameter and is a sizable member of the Apollo asteroids, a subgroup of near-Earth asteroids which cross the orbit of Earth. It was discovered by American astronomer Henry L. Giclas at the U.S Lowell Observatory in Flagstaff, Arizona, on 12 December 1947. After its discovery, the body became a lost asteroid for 32 years and was recovered under the provisional designation 1979 XA, by the American astronomers Passey and Bus at the Californian Palomar Observatory in 1979.
Due to its size and its Earth minimum orbit intersection distance (MOID) of 0.0031 AU (460,000 km), which is only about 1.2 lunar distances, the near-Earth Apollo asteroid is also a potentially hazardous object. It orbits the Sun at a distance of 0.6–3.7 AU once every 3 years and 3 months (1,172 days). Its orbit has an eccentricity of 0.71 and an inclination of 3° with respect to the ecliptic.
It has a rotation period of 26 hours. The stony asteroid is classified as a Sq-subtype in the SMASS taxonomic scheme, with a geometric albedo of 0.24. An alternative and exceptionally high albedo of 0.43 was determined by 11 observations from the Infrared Astronomical Satellite, IRAS.
