The metallicity is listed as -0.55 [1]. Metallicity is on a logarithmic scale [2], so that's about 58% as many heavy elements as our solar system. That seems freakishly high for a star that old. That might be the only reason it has planets at all. There aren't any heavy elements to make planets with in most stars that age.
