| Description | The Reticle — the crosshairs or grid in a telescope's eyepiece used to precisely measure star positions — was created by Lacaille to honor the instrument he relied upon for his landmark southern sky survey. The constellation contains Zeta Reticuli — a binary system of two Sun-like stars just 39 light-years away that orbit each other at a wide separation. Zeta Reticuli gained cultural fame in the 1960s when it was controversially proposed as the origin point of an alleged alien abduction case — making it one of the few constellations to gain popular recognition through modern mythology rather than ancient tradition, and a reference in science fiction to this day. |
