In a previous post, I discussed Pluto and the existence of planets in orbit around other stars (exoplanets). Since then, NASA has announced and held a press conference on Wednesday announcing further discoveries in this field. In the conference, NASA provided details of an exoplanet system located around a relatively close star. The star, Trappist-1 is an ultra cool red dwarf, much smaller than our Sun and located 39 light years from Earth. The star plays host to a remarkable planetary system.
