Caelum, The Chisel Constellation Facts and Mythology

Caelum Constellation Star Map

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. Caelum is the 81st largest in terms of size in the night sky.

The constellation 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.

There are 4 stars that make up the main constellation. The hipparcos satellite scanned and detailed 342 stars. There are 7 stars that can be seen with the naked eye in the constellation on a very clear night sky.

Caelum is not a member of the Zodiac group of twelve constellations that appear when the Sun sets. Caelum is a southern hemispheric constellation which means it can't be seen easily or at all from the northern hemisphere.

The distance to Caelum is not calculable because all the stars that make up the constellation are at various distances. The best answer for distance to Caelum is to calculate the average distance of the stars.

There are 2 Extrasolar Planets (Exoplanets) in this constellation that are detailed on this site. There is a dedicated page for exoplanets in Caelum. For a list of named stars, that is stars that don't start HD or HIP, please visit Caelum Star List Page.

There are no deep space objects that were identified by Charles Messier in this constellation. There are no non-Messier deep space objects in this constellation that are covered at present on this site.
