Delta Apodis
Delta Apodis (δ Aps, δ Apodis) is the Bayer designation for a double star in the southern constellation of Apus. The brighter star, δ¹ Apodis, is a M-type red giant and has an apparent magnitude that varies from magnitude +4.66 to +4.87. 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 δ² Apodis, an orange K-type giant with an apparent magnitude of +5.27. Hipparcos data report the distance to δ¹ Apodis to be approximately 760 light years, while δ²  Apodis is found to be around 610 light years from Earth. They may form a common proper motion pair. Naming. In Chinese caused by adaptation of the European southern hemisphere constellations into the Chinese system, (), meaning "Exotic Bird", refers to an asterism consisting of δ Apodis, ζ Apodis, ι Apodis, β Apodis, γ Apodis, δ Octantis, η Apodis, α Apodis and ε Apodis. Consequently, δ Apodis itself is known as (, .)
