WASP-6
WASP-6, also officially named Márohu, is a type-G yellow dwarf star located about 651 light-years (200 parsecs) away in the Aquarius constellation. Dim at magnitude 12, it is visible through a moderate sized amateur telescope. The star is about 80% of the size and mass of the Sun and it is a little cooler. Starspots in the WASP-6 system helped to refine the measurements of the mass and the radius of the planet WASP-6b.
