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.
The S-type asteroid orbits the Sun at a distance of 3.0–3.2 AU once every 5 years and 5 months (1,988 days). Its orbit has an eccentricity of 0.04 and an inclination of 9° with respect to the ecliptic.
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 7001443000000000000♠44.3±0.1 hours with a brightness variation of 0.47 magnitude (U=2+).
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. 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.
