1611 Beyer, provisional designation 1950 DJ, is a carbonaceous asteroid from the outer region of the asteroid belt, about 25 kilometers in diameter. It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory on 17 February 1950.[8]
The asteroid orbits the Sun at a distance of 2.7–3.7 AU once every 5.66 years (2,067 days). Its orbit shows an eccentricity of 0.16 and is tilted by 4 degrees to the plane of the ecliptic. Its rotation period has been determined to take about 13 hours and 30 minutes.[6] The C-type body has an albedo between 0.06 and 0.10. according to the surveys carried out by Akari and WISE/NEOWISE.[4][5]
It was named by the discoverer after Max Beyer (1894–1982), astronomer at the Bergedorf Observatory in Hamburg.[2]
