This artist's conception shows the KOI-961 planetary system. The system hosts the three smallest planets known to orbit a star beyond our sun (called KOI-961.01, KOI-961.02 and KOI-961.03). The smallest of these planets, KOI-961.03, is about the same size as Mars. All three planets take less than two days to whip around their star. Illustration courtesy of Caltech
