170 Maria is a Main belt asteroid that was discovered by French astronomer Henri Joseph Perrotin on January 10, 1877. Its orbit was computed by [3 ] 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. [4 ]
Tholen classification system, this is categorized as a stony S-type asteroid. Observations performed at the Palmer Divide Observatory in [2 ] Colorado Springs, Colorado during 2007 produced a light curve with a period of 13.120 ± 0.002 hours and a brightness range of 0.21 ± 0.02 in magnitude. Previous measurements from 2000 gave 13.14 and 5.510 hour estimates for the period. Based upon its spectrum, it is classified as an [5 ] S-type asteroid.
occultation of a star by Maria was observed from Manitoba, Canada, on June 10, 1997.
