Caelum (pronounced /ˈsiːləm/) is a faint constellation in the southern sky, introduced in the eighteenth century by Nicolas Louis de Lacaille. Its name means "the chisel" in Latin, and it was formerly known as Cæla Sculptoris, "the sculptor'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, and the one closest to earth at 65.7 light years, is the magnitude 4.45 α Caeli.

A small telescope splits γ Caeli into a magnitude 4.5 red giant and a magnitude 6.34 white giant. Larger telescopes are needed to see several NGC objects, all galaxies, but none brighter than magnitude 11.5 or larger than 3 arcseconds.^[1]
