Just like Snow White, the sleepy, ultra-cool star TRAPPIST-1 is surrounded by seven little friends. Just in this case, those friends aren't short of stature but rather earth-sized planets! It's the first system discovered with seven similar exoplanets, three of which at least are in the star's habitable zone.
Lots of great info, pix, animations, etc. here on this discovery: https://exoplanets.nasa.gov/trappist1/
