The Nysa family (adj. Nysian; FIN: 405) is part of the Nysa–Polana complex, the largest cluster of asteroid families in the asteroid belt.[1]{{rp|23}} It is located in the inner region of the asteroid belt, orbiting the Sun between 2.41 and 2.5 AU. Asteroids in this complex have eccentricities between 0.12 and 0.21 and inclinations of 1.4 to 4.3.[1] The family derives its name from its most massive member, 44 Nysa. It has also been known as the Hertha family (adj. Herthian) named after 135 Hertha. SubdivisionAsteroids in this complex are typically divided into the stony Nysa and carbonaceous Polana subgroups, two mineralogically different families:
