151 Abundantia
Abundantia (minor planet designation: 151 Abundantia) is a stony main belt asteroid. It was discovered by Johann Palisa on 1 November 1875, from the Austrian Naval Observatory in Pula. The name was chosen by Edmund Weiss of the Vienna Observatory; although the name refers to Abundantia, a Roman goddess of luck, it was also chosen to celebrate the increasing numbers of asteroids that were being discovered in the 1870s.
