  More information about Procyon

  Procyon is close rather than powerful: at 11.4 light years it is one of
  our nearest neighbours, and it would be unremarkable at any real
  distance. Its name is the Greek Προκύων, "before the dog", and it is
  practical advice rather than description, because from the middle
  northern latitudes it climbs over the horizon about half an hour ahead
  of Sirius, the dog star. Like Sirius it has a white dwarf companion, the
  cooling core of a star that has stopped burning, invisible without a
  good telescope. It is the brighter of the two stars that make up Canis
  Minor.

  Etymology
  From        Greek
  Reading     Prokyon  ·  Προκύων
  Literally   before the dog

  Bayer lettered the stars of each constellation in his Uranometria of
  1603, in order of brightness. He was working from Tycho's magnitudes by
  eye, and the order he recorded is often wrong.

  First published in 1930 by Yale astronomer Frank Schlesinger, and
  maintained since, the Yale Bright Star Catalogue lists every star down
  to magnitude 6.5. It contains 9,110 stars.
