KOI-351 is a dwarf star, hosting seven extrasolar planets, approximately 2,721 light years away from Earth. It has been nicknamed "Solar System II", because of its similarities with our Solar System. However, unlike our Solar System, these planets orbit much closer to the host star. It is the first seven planet system discovered by Kepler.
