During the period of Dec. 15, 2016 and March 4, the Kepler spacecraft, operating as the K2 mission, observed TRAPPIST-1, an ultra-cool dwarf star home to seven Earth-size planets that are likley rocky. At image center is the light from TRAPPIST-1 collected by Kepler's onboard camera.

New observational data of the TRAPPIST-1 system from Kepler are expected to allow astronomers to refine the previous measurements of six planets, pin down the orbital period and mass of the seventh and farthest planet, TRAPPIST-1h, and learn more about the magnetic activity of the host star.
