Historia

Gamma Gruis has no traditional proper name. Grus was created by Petrus Plancius in the late 16th century from observations by Dutch navigators. Before Grus was recognized as a separate constellation, its stars were considered part of neighboring Piscis Austrinus.

Datos Curiosos

The color contrast between blue-white Gamma Gru and deep red Beta Gru makes them one of the more striking naked-eye color pairs in the southern sky, reminiscent of the famous Albireo estrella doble en el Cisne.
