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.^[6]

Information from A. Harris as of 1 March 2001 indicates that 151 Abundantia is an S class (stony) asteroid with a diameter of 45.37 km and H = 9.24 .1728 and albedo of 0.03. The light curve collected over 6 nights from 2/16/2002 to 3/10/2002 confirmed the rotational period to be 19.718h.^{[citation needed]}

Data from 2001 shows a diameter of 45.37 km.^[7] An occultation by the asteroid was observed on 10 December 2017, showing the asteroid to be highly elongated, with dimensions of roughly 24 x 52 km.^{[citation needed]}
