Planetary system
It has a planet that was discovered by transit photometry in 2011 by the SuperWASP program. Fourteen transits were observed over three watching seasons, each lasting 214 minutes and reducing the stars' brightness by 14 millimagnitudes. The planet has around 0.6 times the mass of Jupiter and an orbital period of 4.6 days. The planet possibly has a large core of heavy metals.
