15374 Teta, provisional designation 1997 BG, is bright, stony asteroid from the inner regions of the asteroid belt, about 3.3 kilometers in diameter. It was discovered by Czech astronomers Miloš Tichý and Zdeněk Moravec at Kleť Observatory in South Bohemia on 16 January 1997.[6]
The bright E-type asteroid is a member of the Hungaria family, which form the innermost dense concentration of asteroids in the Solar System. It orbits the Sun at a distance of 1.7–2.3 AU once every 2 years and 10 months (1,028 days). Its orbit is heavily tilted by 32 degrees to the plane of the ecliptic and shows an eccentricity of 0.16.[1]
In 2014, a photometric light-curve observation with an improved period solution over a 2009-analysis at the U.S. Palmer Divide Observatory, Colorado, rendered a rotation period of 2.820±0.005 hours with a brightness amplitude of 0.30 in magnitude.[4][5] The Collaborative Asteroid Lightcurve Link (CALL) assumes a high albedo of 0.30, a typical value for the bright E-class asteroids of this family, which is named after its largest member, the asteroid 434 Hungaria.[3]
The minor planet was named from Czech mythology after the fortune-teller, heathen priestess, and member of the Přemyslid dynasty, Teta. She is the second daughter of Duke Krok and sister of Libuše, who, according to legend, founded the city of Prague (also see 2367 Praha) in the 8th century, and after whom the minor planets 264 Libussa and 3102 Krok were named, respectively.[2]
