Three possibly habitable Earth sized planets were found orbiting a dim, cold, ultra cool dwarf star that is barely bigger than Jupiter. The star was originally called 2MASS J23062928-0502285 but after the discovery of the three exoplanets, it was renamed to TRAPPIST-1, after the telescope that discovered this star so that it is easier, and much faster to pronounce. and easier too remember. It is located about 39 light-years from here. It is about 2,000 times less bright than the sun, one eighth its width, one twelfth its mass, and half as hot.
The three planets are about 10% bigger than Earth and the first two planets' orbit is 60 to 90 times closer to the sun than Earth is but due to their star's small size, it is kind of proportional. Since they are so close to their star, they were forced to become like Uranus, spinning on their side. One year on those planets are 1.5 and 2.4 Earth days respectively. The third planet might be in the habitable zone and the first two planets have daysides that are too hot and nightsides that are too cold, but in between those two sides, there might be a spot that would be just perfect in temperature.
