WASP-6 is a type-G yellow dwarf star located about 600 light-years 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.[4] Starspots in the WASP-6 system helped to refine the measurements of the mass and the radius of the planet WASP-6b.[5]
Planetary system
The SuperWASP project announced that this star has an extrasolar planet, WASP-6b, in 2008. This object was detected by the astronomical transit method.[3]
Naming
In 2019 the IAU announced that WASP-6 and its planet WASP-6b would be given official names chosen by the public from the proposals collected in a national campaign from The Dominican Republic.[6][7] The star WASP-6 is named Márohu and its planet Boinayel from the proposal received by Marvin del Cid. Márohu the god of drought is the protector of the Sun.[8][9]
