#PPOD: On 1 November 1977, a new minor planet, 2060 Chiron, was found in images taken at Palomar Observatory. Centaurs are small objects that orbit somewhere between the asteroid belt and the Kuiper Belt, often having the characteristics of both asteroids and comets. This image from the Hubble Space Telescope shows the faint coma that surrounds Chiron, which was first seen in 1989. Credit: NASA/ESA/Hubble Space Telescope/Karen Meech
