Planets Transiting Red Dwarf Star In Trappist-1 Giant Coffee Mug
This illustration shows two Earth-sized worlds passing in front of their parent red dwarf star, which is much smaller and cooler than our sun. The planets, TRAPPIST-1b and TRAPPIST-1c, reside 40 light-years away. They are between 20 and 100 times closer to their star than Earth is to the sun.
