1043 Beate, provisional designation1925 HB, is a stonyasteroid from the outer region of theasteroid belt, approximately 32 kilometers in diameter. It was discovered by German astronomerKarl Reinmuth at theHeidelberg-Königstuhl State Observatory on 22 April 1925.[13] Any reference of its name to a person is unknown.[3]
Beate orbits the Sun in theouter main-belt at a distance of 3.0–3.2 AU once every 5 years and 5 months (1,990 days). Its orbit has aneccentricity of 0.04 and aninclination of 9° with respect to theecliptic.[1] The asteroid'sobservation arc begins at the discovering observatory in May 1925, 3 weeks after its official discovery observation.[13]
In theTholen classification,Beate is a commonS-type asteroid.[1]
In April 2006, a rotationallightcurve ofBeate was obtained from photometric observations by American astronomerBrian Warner at his Palmer Divide Observatory (716) in Colorado. It gave a longer-than averagerotation period of44.3±0.1 hours with a brightness variation of 0.47magnitude (U=2+).[11][a]
According to the surveys carried out by the Infrared Astronomical SatelliteIRAS, the JapaneseAkari satellite, and NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission,Beate measures between 31.6 and 41.0 kilometers in diameter and its surface has analbedo between 0.128 and 0.241.[5][6][7][8][9] TheCollaborative Asteroid Lightcurve Link derives an albedo of 0.2517 and a diameter of 31.85 kilometers with anabsolute magnitude of 9.6.[4]
For thisminor planet, any reference of its name to a person or occurrence is unknown.[3]
Among the many thousands ofnamed 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 between164 Eva and1514 Ricouxa and were discovered between 1876 and the 1930s, predominantly by astronomersAuguste Charlois,Johann Palisa,Max Wolf andKarl Reinmuth.[14]
