Reticulum (Pronounciation:Re-tick-u-lum, Abbrev:Ret, Latin:Reticuli) is a constellation, one of 88 constellations that the night sky is divided into. The sky is not divided up equally between the constellations. Reticulum takes up 113.936 sq. degrees of the night sky which equates to 0.28% of the night sky. Reticulum is the 82nd largest in terms of size in the night sky.

The constellation name means The Net . 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 5 stars that make up the main constellation. The hipparcos satellite scanned and detailed 329 stars. There are 16 stars that can be seen with the naked eye in the constellation on a very clear night sky.

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

There are 12 Extrasolar Planets (Exoplanets) in this constellation that are detailed on this site. There is a dedicated page for exoplanets in Reticulum.

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.
