Its orbit was computed by Antonio Abetti, and the asteroid was named after his sister, Maria. This is the namesake of the Maria asteroid family; one of the first asteroid families to be identified by Japanese astronomer Kiyotsugu Hirayama in 1918. This family may be the parent body of the large near-Earth objects 433 Eros and 1036 Ganymed. This object is orbiting the Sun at a distance of 2.55 AU with a low eccentricity of 0.063 and an orbital period of 4.08 years. The orbital plane is inclined at an angle of 14.4° to the plane of the ecliptic. The diameter of this body has been measured as 44.3 km. In the Tholen classification system, this is categorized as a stony S-type asteroid based on its spectrum. Observations performed at the Palmer Divide Observatory in Colorado Springs, Colorado during 2007 produced a light curve with a period of 13.1200.002 hours and a brightness range of 0.210.02 in magnitude. Previous measurements from 2000 gave 13.14 and 5.510 hour estimates for the period. An occultation of a star by Maria was observed from Manitoba, Canada, on 10 June 1997.
