Article Summary
Astronomers using data from NASA's Kepler mission have discovered the tiniest solar system found so far. The system consists of a single red dwarf star, known as KOI-961 and three planets which are 0.78, 0.73 and 0.57 times the radius of Earth. The planets are thought to be rocky - like Earth - but orbit much closer to their star making them too hot to be habitable.
