Delta Apodis (δ Aps / δ Apodis) is a double star in the constellation Apus.
The brighter of the pair, δ¹ Apodis, is a M-type red giant with a mean apparent magnitude of +4.68. It is classified as an irregular variable star and its brightness varies from magnitude +4.66 to +4.87. At a 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 770 light years, while δ² Apodis is found to be approximately 663 light years from Earth. The error in these measurements are such that it is not certain if these two stars form a gravitationally bound system. They have a common proper motion, which lends support to the idea that they are gravitationally interacting.
