About Fuyue

Description

Fuyue is a K-type giant of spectral class K2 III about 126 light-years away, located in the central part of Scorpius near the heart of the constellation. It shines at magnitude 3.21 with a warm orange hue. Fuyue has no resolved companions and is a red-clump giant actively fusing helium in its core.

Observing Tips

Fuyue lies in the central body of Scorpius, near Antares. In binoculars it appears as a clean warm-yellow point. Best observed May through September.

History

The IAU adopted the name Fuyue in 2017 — a Chinese name referring to a legendary figure (Fu Yue) who, according to traditional Chinese mythology, was transferred to the sky as a celestial minister after his death. The pairing of Chinese and Arabic star names in this region reflects Scorpius's rich multi-cultural history.

Fun Facts

The Chinese-origin name Fuyue is one of a small number of non-Western names in the official IAU catalog, alongside Xamidimura, Pipirima, Chamukuy, Ginan, Taiyangshou, and a handful of others. This naming effort aims to broaden the cultural base of recognized stellar nomenclature.
