Caelum takes up 124.865 sq. degrees of the night sky which equates to 0.3% of the night sky. The constellation gets its name as it name means The Chisel . It was not one of the original constellations that had been devised by Ptolemy, instead it was created by Abbé Nicolas Louis de Lacaille years later.

List of Named Stars in Caelum without Extrasolar Planets

As there's so many stars in the cosmos, not all the stars are listed here. The site has lots of stars not listed so if your star isn't listed and you know the Henry Draper or Hipparcos ID, type https://www.universeguide.com/star/ then followed by the HIPNNNNNN or HDNNNN where NNNNN is the number part of the name. The stars that I do list have either a traditional name, a bayer or other classification name.
