1980 Tezcatlipoca
1980 Tezcatlipoca, provisional designation 1950 LA, is a near-Earth object and Amor asteroid about 4.3 kilometers in diameter. It was discovered on June 19, 1950 by American astronomer Albert George Wilson and Swedish astronomer Åke Wallenquist at Palomar Observatory in San Diego County, California.〔
The eccentric asteroid orbits the Sun at a distance of 1.1–2.3 AU once every 2 years and 3 months (816 days). It has a rotation period of 7.2 hours. The relatively bright, stony asteroid with a geometric albedo of 0.25 is classified as SU and Sl in the Tholen and SMASS taxonomy system, respectively. Its Earth minimum orbit intersection distance is slightly less than 0.25 AU.〔
The asteroid was named after Tezcatlipoca, the Aztech deity of matter, whose name translates to "Smoking Mirror" in the Nahuatl language. His animal counterpart was the jaguar and his contender was Quetzálcoatl, after which the minor planet 1915 Quetzalcóatl is named. Both deities were depicted as twin serpents that coil round each other to produce time.〔
