HD 179079 b

HD 179079 b is an extrasolar planet which orbits the G-type subgiant star HD 179079, located approximately 228 light years away in the constellation Aquila. This planet has mass only 1/12 that of Jupiter or 1.5 times Neptune. The planet orbits very close to the star, at a distance of 0.11 AU. This planet takes two weeks to revolve around the star.[1] This planet was discovered using the Keck telescopes on August 12, 2009.
