1726 Hoffmeister
1726 Hoffmeister, provisional designation 1933 OE, is a dark, carbonaceous asteroid from the outer region of the asteroid belt, about 26 kilometers in diameter. It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory on 24 July 1933.〔
The C-type asteroid with a Cb-subtype in the SMASS taxonomy, orbits the Sun at a distance of 2.7–2.9 AU once every 4 years and 8 months (1,701 days). Its orbit shows an eccentricity of 0.04 and is tilted by 3 degrees to the plane of the ecliptic. It has a rotation period of 11.7 hours〔 and an very low geometric albedo of 0.04. It is the lowest-numbered and probably the largest member of the small, very compact dynamical ''Hoffmeister family''. Based upon the low albedo, it was most likely formed from the breakup of a carbon-rich asteroid about 50–100 km in diameter within the past several hundred million years.〔
The minor planet was named in memory of German astronomer Cuno Hoffmeister (1892–1968), founder and later director of the Sonneberg Observatory after which the asteroid 1039 Sonneberga is named. He was best known as a prolific discoverer and observer of variable stars, for his extensive work on meteors, and for the discovery of a comet and several minor planets. The minor planet 4183 Cuno and the lunar crater ''Hoffmeister'' are also named in his honor.〔
