1284 Latvia, provisional designation 1933 OP, is a dark asteroid with a rare reddish spectral type from the middle region of the asteroid belt, about 37 kilometers in diameter. It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory in southern Germany on 27 July 1933.[11]
The asteroid is classified as a rare T-type and L-type in the Tholen and SMASS taxonomy scheme, respectively, both indicating a featureless spectra of a dark and reddish body. It orbits the Sun at a distance of 2.2–3.1 AU once every 4 years and 4 months (1,572 days). Its orbit shows an eccentricity of 0.17 and is tilted by 11 degrees to the plane of the ecliptic. It has a rotation period of 9.6 hours.[8] According to the surveys carried out by the Infrared Astronomical Satellite, IRAS, the Japanese Akari satellite, and the Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, it has a geometric albedo that lies between 0.06 and 0.10.[4][5][6][7]
The minor planet is named after the Republic of Latvia.[2]
