HD 330075 b
HD 330075 b is an extrasolar planet approximately 164 light-years away in the constellation of Norma. This planet orbits the star HD 330075. It was discovered by the Geneva Extrasolar Planet Search team at ESO's La Silla Observatory using the HARPS spectrograph.
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 an example of a hot Jupiter. One orbit around the star takes a
a cool orange donor star. The black hole is a microquasar, firing off jets of material most likely from its accretion disk.
Four star systems are known to harbour planets. HD 330075 is a sunlike star around 164 light-years distant that is orbited by a hot Jupiter every 3.4 days. Announced in 2004, it was the first planet discovered by the HARPS spectrograph. HD 148156 is a star 168 ± 7 light-years distant. Slightly larger and hotter than the Sun, it was found to
