Delta Apodis (δ Aps, δ Apodis) is the Bayer designation for a double star in the southern constellation of Apus.
The brighter star, δ Apodis, is an M-type red giant and has an apparent magnitude that varies from magnitude +4.66 to +4.87.[1] It is classified as a semiregular variable with pulsations of multiple periods of 68.0, 94.9 and 101.7 days. At an angular separation of 102.9 arcseconds is δ Apodis, an orange K-type giant with an apparent magnitude of +5.27.
Hipparcos data report the distance to δ Apodis to be approximately 760 light years, while δ Apodis is found to be around 610 light years from Earth. They may form a common proper motion pair.
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 δ1 Apodis, ζ Apodis, ι Apodis, β Apodis, γ Apodis, δ Octantis, η Apodis, α Apodis and ε Apodis. Consequently, δ1 Apodis itself is known as Chinese: 異雀六 (Chinese: Yì Què liù, English: the Sixth Star of Exotic Bird.)[2]
