Reticulum is a small, dim constellation in the Southern Hemisphere. It is best viewed in January.

It was created by Nicolas Louis de Lacaille in the mid-1700s and is one of 15 constellations he developed to fill the southern night sky. He named it after the reticle; a reticle is a set of lines in the eyepiece of a device (such as a microscope or a gun sight) that is used for measuring and locating objects. They are sometimes used in telescopes to locate stars and other astronomical entities.

Reticulum is sometimes called "the Net" instead of "the Reticle."


There is no mythology associated with this constellation.
