Indus (pronounced /ˈɪndəs/) is a southern constellation that represents a native of Asia or the Americas.

The brightest star in the constellation, Alpha Indi, is visual magnitude 3.11.

Epsilon Indi is one of the closest stars to Earth, approximately 11.82 light years away. The system has been discovered to contain a pair of binary brown dwarfs, and has long been a prime candidate in SETI studies.

[edit] History

The constellation was one of twelve constellations created by Petrus Plancius from the observations of Pieter Dirkszoon Keyser and Frederick de Houtman and it first appeared on a 35-cm diameter celestial globe published in 1597 (or 1598) in Amsterdam by Petrus Plancius and Jodocus Hondius. The first depiction of this constellation in a celestial atlas was in Johann Bayer's Uranometria of 1603.[2][3] Plancius portrayed the figure as a nude male with arrows in both hands but no bow.[4]

Since Indus was introduced in the late 16th century, and lies in the south, it was not known to classical or early European cultures. Thus they produced no mythology concerning it.
