HD 75289
A star, similar to the Sun but somewhat brighter, in the constellation of
Vela. Around it has been found an epistellar
jovian, the sixth in order of discovery, with a mass only 1.4 times
that of Saturn. HD 75289 appears to be similar
in age to the Sun, although, as in the case of most other stars with known
giant planets, its metal content is about twice the solar composition. See
also extrasolar planets.
