Omicron Indus
Cool red starWhat is Omicron Indus
Omicron Indi is a red giant some 544 light-years away, with 322 times the Sun's luminosity and the deep hue of a star that has already passed through the great transformations of age. Indus —the Indian— is another of the constellations born on Dutch 16th-century charts, and Omicron is one of its more distant embers, set adrift between Grus and the Southern Fish.
