Asteroid 44 Nysa is head of the Nysian family of main belt asteroids. It is a type E asteroid, a group thought to have surfaces of the orthorhombic silicate enstatite, a name I remember well from my days spent hopelessly trying to remember mineral compositions for Mr Hughes’ A-Level Geology class.
Nysa was discovered on May 27th 1857 by our old friend Hermann Goldschmidt, and named not after a person or mythical creature, but a place. Nysa was a mythological land, linked to Africa , Arabia, or more likely India, where Dionysus was raised by the Hyades.
Because of the rarity of E types, Nysa has been the subject of some scrutiny, and has attracted that attention of both the most famous space-borne telescope (Hubble) and what was until 2016 the biggest ground-based one (the 1,000 foot Arecibo dish in Puerto Rico). There are suggestions that Nysa might not be a single bosy, but a “contact binary”.
