Erik Prosperin was an 18th century Swedish astronomer. He was a famous calculator of orbits: comets, planets, and their satellites, including Comet Montaigne (C/1774 P1). Comet of 1819 (289P/Blanpain, formerly D/1819 W1 Blanpain) is a short-period comet. Biela's Comet or Comet Biela (3D/Biela) was a periodic Jupiter-family comet. It was observed to split in two and has not been seen since 1852. As a result it is currently considered to have been destroyed, although remnants appeared to have survived for some time as a meteor shower, the Andromedids. Image from Astronomy (1875) by J.
