HD 97413 is a binary star in the constellation Centaurus. With a combined magnitude of 6.27, the system is only visible under ideal conditions. HD 97143 is located 275 light-years (84 pc) away from the Solar System based on parallax, but it’s unknown if the system is drifting closer or away from it.

Properties

The visible component, HD 97143A, is an A-type main-sequence star with 1.93 times the Sun’s mass, and has 2.135 times the Sun’s radius. It radiates at 17 solar luminosities, and has a white-hue, which corresponds to an effective temperature of 8,006 K. The second component, HD 97143B, is a star with an apparent magnitude of 9.45, and is 0.2 arc-seconds away from the primary. [8] At a distance of 84.5 parsecs, this corresponds to a projected separation of 16.9 AU. HD 97143A is metal-deficient, with 50.12% the abundance of heavy metals compared to the Sun.
