Mu Arae d

Mu Arae d (also known as HD 160691 d) is an extrasolar planet orbiting the star Mu Arae. The planet has a mass about half that of Jupiter and orbits at a distance of 0.921 AU from the star with a period of 310.55 days. The planet may be located at a distance close enough to the star to receive a comparable amount of ultraviolet radiation as the Earth does from the Sun, however it is too close to the star to be able to support liquid water at its surface. Furthermore, given its mass, the planet is likely to be a gas giant with no solid surface.
