StarHD 330075

    The planet has a mass about three quarters that of Jupiter. Its orbital distance from the star is less than 1/23rd Earth's distance from the Sun, which makes HD 330075 b an example of a hot Jupiter. One orbit around the star takes a little more than 3 Earth days to complete, as compared to one year for the Earth around the Sun.[1]
