26074 Carlwirtz, provisional designation 1977 TD, is a binary Hungaria asteroid and Mars-crosser, approximately 3 kilometers in diameter. It was discovered on 8 October 1977, by German astronomer Hans-Emil Schuster at ESO's La Silla Observatory in northern Chile.[2] Its orbiting minor-planet moon was discovered in 2013.[5]
Naming
This minor planet was named after Carl Wilhelm Wirtz (1875–1939), a German astronomer at Strasbourg and Kiel observatories. In 1924, he revealed statistically the redshift-distance relationship of spiral nebulae. The official naming citation was published by the Minor Planet Center on 28 September 2004 (M.P.C. 52769).[8]
