Maria family

The Maria or Marian asteroids are a group of about 89 asteroids that orbit the Sun with distances between about 2.52−2.62 AU. They were initially identified by Japanese astronomer Kiyotsugu Hirayama in 1918.[1] Asteroids in this family typically have an inclination of 12 to 17 degrees.[2] The family gets its name from its lowest numbered member, the asteroid 170 Maria.

Although asteroid 695 Bella has orbital properties that make it a candidate for this dynamic family, the spectral properties of the object indicate it is most likely an interloper. Instead, it may have been spalled off from 6 Hebe, or its parent body.[1]
