1043 Beate, provisional designation 1925 HB, is a stony asteroid from the outer region of the asteroid belt, approximately 32 kilometers in diameter. It was discovered by German astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory on 22 April 1925. [13] Any reference of its name to a person is unknown. [3]
Beate orbits the Sun in the outer main-belt at a distance of 3.0–3.2 AU once every 5 years and 5 months (1,990 days). Its orbit has an eccentricity of 0.04 and an inclination of 9 ° with respect to the ecliptic. [1] The asteroid's observation arc begins at the discovering observatory in May 1925, 3 weeks after its official discovery observation. [13]
In the Tholen classification, Beate is a common S-type asteroid. [1]
In April 2006, a rotational lightcurve of Beate was obtained from photometric observations by American astronomer Brian Warner at his Palmer Divide Observatory ( 716) in Colorado. It gave a longer-than average rotation period of 44.3±0.1 hours with a brightness variation of 0.47 magnitude ( U=2+). [11] [a]
According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Beate measures between 31.6 and 41.0 kilometers in diameter and its surface has an albedo between 0.128 and 0.241. [5] [6] [7] [8] [9] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.2517 and a diameter of 31.85 kilometers with an absolute magnitude of 9.6. [4]
For this minor planet, any reference of its name to a person or occurrence is unknown. [3]
Among the many thousands of named minor planets, Beate is one of 120 asteroids, for which no official naming citation has been published. All of these low-numbered asteroids have numbers between 164 Eva and 1514 Ricouxa and were discovered between 1876 and the 1930s, predominantly by astronomers Auguste Charlois, Johann Palisa, Max Wolf and Karl Reinmuth.
