1998 Titius is an asteroid discovered in 1938 by Alfred Bohrmann at Heidelberg.[2] It is named after the German astronomer Johann Daniel Titius, best known for formulating the Titius-Bode law along with Johann Elert Bode. Based upon photometric measurements made at the Santana Observatory, this object has a rotation period of 6.13 ± 0.01 hours, during which it varies in magnitude by 0.30 ± 0.04.[1] It has a 2:1 orbital resonance with the planet Mars.[3]
