170 Maria is aMain beltasteroid that was discovered by French astronomerHenri Joseph Perrotin on January 10, 1877.[3] Its orbit was computed byAntonio Abetti, and the asteroid was named after his sister, Maria. This is the namesake of theMaria asteroid family; one of the firstasteroid families to be identified by Japanese astronomerKiyotsugu Hirayama in 1918.[4] This family may be the parent body of the largenear-Earth objects433 Eros and1036 Ganymed.[5]
In theTholen classification system, this is categorized as a stonyS-type asteroid based on its spectrum.[2] Observations performed at the Palmer Divide Observatory inColorado Springs, Colorado during 2007 produced alight curve with a period of 13.120 ± 0.002 hours and a brightness range of 0.21 ± 0.02 inmagnitude. Previous measurements from 2000 gave 13.14 and 5.510 hour estimates for the period.[6]
Anoccultation of astar by Maria was observed fromManitoba, Canada, on June 10, 1997.
