A Mini-Planetary System

Astronomers using data from NASA's Kepler mission have discovered the cutest planet system yet: three planets, the smallest yet found, orbiting a red dwarf, the system being comparable to the size of the Jupiter-moon system. The planets orbit a single star, called KOI-961, and are 0.78, 0.73 and 0.57 times the radius of Earth. The smallest is about the size of Mars. This is a remarkable demonstration of the exquisite planet-finding capability of the Kepler instrument.

One is within the habitable zone of the star, though that zone is 90% closer to the star then mercury is to our star. If the planet supports life, it'll be a very red dawn, day and sunset.
