BD-08°2823 b (also known as HIP 49067 b) is an extrasolar planet which orbits the K-type main sequence star BD-08°2823, located approximately 137 light years away in the constellation Sextans. This planet has at least 14 times the mass of Earth and takes four-fifths of a week to orbit the star at a semimajor axis of 0.056 AU. This planet is classified as a hot Neptune. This planet was detected by HARPS on October 19, 2009, together with 29 other planets, including BD-08°2823 c.
