HD 75289
HD 75289 is a 6th magnitude star in the constellation of Vela. Like our Sun, it is a yellow dwarf but slightly more massive, hotter and luminous. The spectral type of the star is G0 V. Under exceptionally good circumstances it might be visible to the unaided eye; however, usually binoculars are needed.
In 2004, a possible red dwarf companion was detected.
Planetary system.
In 1999 a planet HD 75289 b with half the mass of Jupiter was detected by radial velocity method
. This planet is a typical hot Jupiter that takes only about 3.51 days to revolve at an orbital distance of 0.0482 AU.
HD 75289 B.
HD 75289 B is a possible red dwarf star orbiting HD 75289. The stars share the same proper motion so they are probably related. Apparent distance between the two stars is about 21.5 arcseconds, at a distance of 94 light years that would be 621 astronomical units. However, the radial distance between the stars is unknown, so they are probably further apart
