Kepler has managed to find another solar system out there, kind of like the one we live in. It has 7 planets, with rocky ones (probably) in close to the star, and gas giants further out. First they found the outer gas giants. Then they found the inner planets.
Here’s the catch, all the planets are within 1 AU of the star. An AU is the distance from the sun to Earth, so this whole solar system is very small. The (possibly) rocky planets would all be within the orbit of Mercury.
