It was discovered on 24 February 1938, by German astronomer Alfred Bohrmann at Heidelberg Observatory in southern Germany.
[9] According to observations carried out by the Japanese Akari and NASA's Wide-field Infrared Survey Explorer (WISE) with its subsequent NEOWISE mission, Titius has an albedo between 0.093 and 0.126, and its diameter measures between 14.2 and 16.0 kilometers.
[4][5][6] The Collaborative Asteroid Lightcurve Link assumes a standard albedo of 0.20 and calculates a diameter of 10.8 kilometers with an absolute magnitude of 12.2.
[5] A rotational lightcurve of Titius was obtained from photometric observations by American astronomer Robert Stephens at the Californian Santana Observatory in March 2002.
Lightcurve analysis gave a rotation period of 6.13±0.01 hours, during which its brightness amplitude varies by 0.30±0.04 magnitude (U=3).
