Beta Apodis (β Aps, β Apodis) is the Bayer designation for a star in the southern circumpolar constellation of Apus. It is located approximately 149abbr=offNaNabbr=off from Earth, as determined by parallax measurements. The apparent visual magnitude of this star is +4.24, which is bright enough to be seen with the naked eye
The spectrum of this star matches the characteristics of a K0 III, which, according to models of stellar evolution, indicates that it is in the giant star stage, having exhausted the supply of hydrogen at its core. The measured angular diameter of this star is . At the estimated distance of this star, this yields a physical size of about 11 times the radius of the Sun. The expanded outer atmosphere of Beta Apodis has an effective temperature of about 4,900 K. This heat is causing it to glow with the characteristic orange hue of a K-type star.
In Chinese caused by adaptation of the European southern hemisphere constellations into the Chinese system, Chinese: 異雀 (Chinese: Yì Què), meaning Exotic Bird, refers to an asterism consisting of β Apodis, ζ Apodis, ι Apodis, γ Apodis, δ Octantis, δ1 Apodis, η Apodis, α Apodis and ε Apodis. Consequently, β Apodis itself is known as Chinese: 異雀三 (Chinese: Yì Què sān, English: the Third Star of Exotic Bird.)[1]
