Planets Aplenty?

The latest exoplanet to be found orbits one of the smallest stars known. In fact, the star, which is 20 light years away, is just barely massive enough to sustain fusion in its core, thus allowing it to shine.

The fact that such small stars can have planets suggests to scientists that planetary systems may be quite common; they may even be a natural part of star formation.
