HR 4180 is a double star with components HD 92449 and HD 92463 in the southern constellation of Vela. They are probably members of a binary star system. HR 4180 can be viewed with the naked eye, having an apparent visual magnitude of 4.29. Based upon the annual parallax shift of the two stars it is located approximately 780 light years from the Sun. The system is moving further from the Earth with a heliocentric radial velocity of +20 km/s.
The primary component of this system, HD 92449, is a bright giant with a stellar classification of G5 IIa. The star radiates 1,370 times the Sun's luminosity from its photosphere at an effective temperature of 5,100 K. It shares a common proper motion with the magnitude 6.06 star HD 92463, and the pair likely form a binary system. This secondary component is a B-type main-sequence star with a class of B8 V. As of 2000, it had an angular separation of along a position angle of 105° from the primary.
