A yellow giant in the
constellation of Gemini. It lies close in
the sky to the brighter and better known stars
Castor and Pollux, and in fact forms the third corner of a
triangle with these two. It is much farther away than either Castor or
Pollux, though, and appears correspondingly fainter.
* Some sources give this star the proper name of Propus, apparently in confusion with Eta Geminorum which normally bears this name. Given that the name Propus means 'leading foot', it clearly belongs more properly to Eta Geminorum in the 'feet' of Gemini, rather than this star near the heads of the Twins.
