About Reticulum

Reticulum was named by Nicolas-Louis de Lacaille after the reticle, the grid of fine threads in a telescope eyepiece that he used to measure the positions of stars. It is a compact diamond of stars, faint but neat, lying between Dorado, Horologium and Hydrus, close to the Large Magellanic Cloud.

Its best-known pair is Zeta Reticuli, two Sun-like stars wide enough apart to be seen separately with the naked eye under a dark sky, travelling through space together. Epsilon Reticuli, the nearest star of the figure, is an orange star accompanied by a white dwarf.

Reticulum lies far enough south to stay above the horizon all night from much of the southern hemisphere, where it is highest on summer evenings. From most of the northern hemisphere it is never seen.
