Artist's concept of extrasolar planet Tau Bootis b over a ?

The extrasolar planet Tau Bootis b reigns over the airless, baked and battered terrain of a hypothetical moon. Tau Bootis b orbits very close to Tau Bootis, a type F7V star about 50 light years from the Earth. Tau Bootis b is believed to have about four times the mass of the planet Jupiter and orbits around its sun at the astonishing pace of once every 3.3 days. Tau Bootis b is so close to its host sun that the force of the solar wind may be enough to constantly blow off the planet's outer atmosphere
