Maria (minor planet designation: 170 Maria) is a Main belt asteroid that was discovered by French astronomer Henri Joseph Perrotin on January 10, 1877.[3] 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.[4]

In the Tholen classification system, this is categorized as a stony S-type asteroid.[2] Observations performed at the Palmer Divide Observatory in 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.[5] Based upon its spectrum, it is classified as an S-type asteroid.
An occultation of a star by Maria was observed from Manitoba, Canada, on June 10, 1997.

(170) Мария (итал. Maria) — небольшой астероид главного пояса, который принадлежит к светлому спектральному классу S и возглавляет одноимённую группу астероидов — семейство Марии. Он был открыт 10 января 1877 года французским астрономом Перротэном в обсерватории Тулузы и назван в честь Марии, сестры итальянского астронома Антонио Абетти, который рассчитал орбиту этого астероида[1].Другой контент может иметь иную лицензию.
