High Quality Content by WIKIPEDIA articles! 30 Arietis Bb is an extrasolar planet which orbits the F-type main sequence star 30 Arietis B, located approximately 129 light years away in the constellation Aries. This planet has minimum mass nearly 10 times that of Jupiter. Because inclination is not known, its true mass is unknown. Maybe in next couple years, the inclination could be determined from astrometry to determine whether this object is indeed a planet or a brown dwarf. This planet is so massive that internal heating would be great enough to raise planet's temperature by several hundred…mehr

High Quality Content by WIKIPEDIA articles! 30 Arietis Bb is an extrasolar planet which orbits the F-type main sequence star 30 Arietis B, located approximately 129 light years away in the constellation Aries. This planet has minimum mass nearly 10 times that of Jupiter. Because inclination is not known, its true mass is unknown. Maybe in next couple years, the inclination could be determined from astrometry to determine whether this object is indeed a planet or a brown dwarf. This planet is so massive that internal heating would be great enough to raise planet's temperature by several hundred kelvins. Meanwhile, this planet orbits only 0.005 AU closer to the star than Earth to the Sun, but its orbital eccentricity is much higher compared to Earth.
