    Description This planet is an orphan planet, which means it is not orbiting any star. Some people therefore argue that it should not be called a planet. The object is associated with the AB Doradus moving group which allows astronomers to determine its age and therefore its mass.

    Planet sizes

    The following plot shows the approximate sizes of the planets in this system The Solar System planets are shown as a comparison. Note that unless the radius has been determined through a transit observation, this is only an approximation (see Lissauer et al. 2011b).
