Caelum (Pronounciation:Cee-lum, Abbrev:Cae, Latin:Caeli) is a constellation, one of 88 constellations that the night sky is divided into. The sky is not divided up equally between the constellations. 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 AbbÃ© Nicolas Louis de Lacaille years later.

The caveat of these stars are that they are catalogued on this site. If you know of a star that is nearer or further then do let me know in the comments and I'll add it to the site. The stars mentioned are from the Hipparcos catalogue or have been added because of their special status.
There is no Greek Legend behind this constellation. It was created by Abbé Nicolas Louis de Lacaille to fill in the voids in the astronomical charts.There are no major meteor showers that radiate from within this constellation.

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.
