Caelum (pron.: //) is a faint constellation in the southern sky, introduced in the 1750s by Nicolas Louis de Lacaille. Its name means "the chisel" in Latin, and it was formerly known as Caelum Scalptorium, "the engraver's chisel". It is the eighth smallest constellation, with an area just less than that of Corona Australis.
Notable features 
Caelum is a faint constellation, having no star brighter than fourth magnitude. Its brightest star is the magnitude 4.45 α Caeli.
- γ Cae is a double star with an orange-hued primary of magnitude 4.6 and a secondary of magnitude 8.1. The primary is 185 light-years from Earth. It is difficult to resolve in small amateur telescopes because of the difference in visual magnitude and the close separation of the two components.
Caelum contains the galaxies NGC 1571, NGC 1679 and IC 2106. Larger telescopes are needed to see several NGC objects, all galaxies, but none brighter than magnitude 11.5 or larger than 3 arcminutes.
