214 Aschera
Main-belt asteroid
From Wikipedia, the free encyclopedia
214 Aschera is a Main belt asteroid. It was discovered by Austrian astronomer Johann Palisa on February 29, 1880, in Pola and was named after the Sidonian goddess Asherah. This minor planet is orbiting the Sun at a distance of 2.61 AU with a low eccentricity of 0.032 and an orbital period of 4.22 yr. The orbital plane is inclined at an angle of 3.44° to the plane of the ecliptic.[2]

It is classified as a rare E-type asteroid and is fairly faint for an object of its type. The overall diameter is estimated to be 23 km and it has a geometric albedo of 0.52.[3] Photometric data collected during September 2021 was used the generate a lightcurve for 214 Aschera. This showed a rotation period of 6.833±0.004 h with a brightness variation of 0.20 magnitude.[4] Using a tri-axial ellipsoidal model derived from light curve data, the overall shape of the asteroid is estimated to be a/b = 1.24 ± 0.12 and b/c = 1.83 ± 0.10, where a, b, c are the three axes of an ellipsoid.[5]
