Maria family (of asteroids)
A Hirayama family of asteroids, with about 70 known members, mostly S-type, that orbits the Sun at a mean distance of 2.55 AU (astronomical units); its members are unusual for main belt asteroids in having a fairly high inclination of about 15°. The prototype and one of the largest of the group is (170) Maria, discovered in 1877 by H. Joseph Perrotin (1845–1904).
