HD 88133 b
HD 88133 b is an extrasolar planet orbiting the star HD 88133. It is probably less massive than Jupiter and even Saturn. It orbits the star in a very tight orbit, completing one revolution around the star in every three and half days or so. Despite the relatively large radius of the star (about 2 times Solar), no transits have been detected.[2]
