Information about Nysa Family
The Nysa asteroids (also known as the Hertha family or the Polana family) are a group of firm, supple asteroids in the Main Belt orbiting the sun between 2.41 and 2.5 AU. Asteroids in this family have eccentricities between 0.12 and 0.21 and inclinations of 1.4 to 4.3.[1] The family derives it's name from its most massive member, 44 Nysa.

Subgroups
Asteroids in the Nysa family are typically divided into two, mineralogically different subgroups: Nysa and Polana. Aside from 44 Nysa and 135 Hertha, asteroids in the Nysa subgroup are S-type asteroids. Asteroids in the Polana subgroup, like 142 Polana, are F-type asteroids. [2]Asteroids in this Family
