30 Arietis Bb (sometimes abbreviated 30 Ari Bb) is an extrasolar planet which orbits the F-type main sequence star 30 Arietis B, located in a quadruple star system approximately 146 light years away in the constellation Aries. The gas giant planet was discovered by on Friday, November 27, 2009 by using precise radial velocity method from echelle spectrograph installed in Alfred-Jensch telescope in Karl Schwarzschild Observatory.
Overview
The exoplanet 30 Arietis Bb has a minimum mass of nearly 10 times that of Jupiter. Because inclination is not identified, its true mass is unknown. Meanwhile, this planet orbits only 0.995 AU (or 700,000 km) closer to the star than Earth to the Sun, but its orbital eccentricity is much higher compared to Earth. At periastron, the planet’s closest distance to the star is 0.708 AU, which is slightly closer to the star than Venus to the Sun. At apastron, the planet’s farthest distance to the star is 1.283 AU, which is more than halfway between the orbits of Earth and Mars.
