Kappa1 Apodis, Latinized from κ1 Apodis, is the Bayer designation for a binary star system in the southern circumpolar constellation of Apus. Based upon parallax measurements, it is located roughly 1060ly from Earth. The combined apparent visual magnitude of the system is 5.52, indicating that this is a faint, naked eye star that can be viewed in dark suburban skies. It is moving away from the Sun with a radial velocity of +62 km/s.
This is a spectroscopic binary system with an orbital period of 0.6 days. The combined spectrum matches a stellar classification of B1npe. The 'e' suffix indicates that this is a Be star with emission lines in the spectrum. An 'n' means that the absorption lines in the spectrum are broadened from the Doppler effect as a result of rapid rotation. Finally, the 'p' shows some peculiarity in the spectrum. It is classified as a Gamma Cassiopeiae type variable star and its brightness varies from magnitude +5.43 to +5.61.
This is a runaway star with a peculiar velocity of . Because it is a binary star system, it was most likely not turned into a runaway system as the result of a supernova explosion. A companion star is a 12th magnitude orange K-type subgiant located at an angular separation of 27 arcseconds.
