Reticulum Constellation
Reticulum constellation is one of the smallest constellations in the southern hemisphere, located between Dorado, Horologium and Hydrus constellations. The brightest star is called Alpha Reticuli with a magnitude of 3.0. The best time to look for it is during culmination in winter times. The constellation was not known to Ptolemy and was first introduced in the 18th century by astronomer de Lacaille. He named some of the constellations in the southern sky that were not named before, and he didn’t want to name them after animals or mythological creatures, and used the technological novelties for its names instead. The name Reticulum means ‘small net’ or ‘the reticle’ in Latin. De Lacaille used to measure the angular distances of the stars and their positions. The constellation existed 100 years before de Lacaille and was depicted by Habrecht II who called it Rhombus, but de Lacaille changed its name later on.

Mythology of the Reticulum Constellation
Due to the fact this constellation was recently discovered, it was not connected with any Greek or Roman myths and tails. The reason for that is that Ptolemy was not able to see the constellations located in the southern hemisphere, and he, therefore, didn’t list this one in his 48 then-known constellations. Reticulum constellation was first depicted by the astronomer from Germany called Isaac Habrecht II in the 17th century by the name Rhombus. Lacaille, a famous French astronomer, was the one who introduced the constellation le Réticule Rhomboide, or Reticulum. He named the constellation after the reticle in his telescope, which he used to measure star positions during his journey in the mid-18th century. The constellation is now officially accepted by International Astronomical Union and listed as one of the 88 modern-known constellations. The constellation could not be spotted without binoculars or a telescope, due to its size and brightness of its stars.
