The apparent magnitude is 8.17, which means it is not visible to the naked eye but can be seen with good binoculars. A search for a binary companion star using adaptive optics at the MMT Observatory was negative.The star is more massive and larger than our Sun while Its absolute magnitude of 3.70 and spectral type of G0, show that it is both hotter and more luminous. Based on asteroseismic density constraints and stellar isochrones, it was found that the age is 3.37 +0.20−0.47 billion years making it about two thirds as old as the sun. Spectral observations show that the star is metal-rich.An extrasolar planet was discovered with the radial velocity method in 2007, it was subsequently discovered to transit the star. At the time it was the transiting planet with the longest period."@en }
