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 Heidelberg-Königstuhl State Observatory on 22 April 1925.[12]

The S-type asteroid orbits the Sun at a distance of 3.0–3.2 AU once every 5 years and 5 months (1,986 days). Its orbit has an eccentricity of 0.04 and an inclination of 9° with respect to the ecliptic.[1]

In April 2006, a rotational light-curve for this asteroid was obtained from photometric observations by American astronomer Brian D. 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+).[9]

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, the asteroid measures between 31.6 and 41.0 kilometers in diameter and its surface has an albedo between 0.128 and 0.241.[4][5][6][7][8] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.2517 and a diameter of 31.85 kilometers, based on an absolute magnitude of 9.6.[3]

Any reference of this name to a person is unknown.[2]
