Trappist - 1 Exoplanets

Guardian UK: Exoplanet discovery: seven Earth-sized planets spotted orbiting nearby star - Exoplanets found orbiting Trappist-1 raise hope that the hunt for alien life beyond the solar system can start much sooner than previously thought
Any life that gained a foothold and the capacity to look up would have a remarkable view from a Trappist-1 world. From the fifth planet, considered the most habitable, the salmon-pink star would loom 10 times larger than the sun in our sky. The other planets would soar overhead as their orbits required, appearing up to twice the size of the moon as seen from Earth. “It would be a beautiful show,” said Amaury Triaud at the Institute of Astronomy at Cambridge University
