TRAPPIST-1 system compared to Earth (February 2018)

TRAPPIST-1 system compared to Earth (February 2018). TRAPPIST-1, also designated as 2MASS J23062928-0502285, is an ultra-cool red dwarf star that is slightly larger but much more massive than the planet Jupiter, located 39.6 light-years (12.1 pc) from the Sun in the constellation Aquarius. Seven temperate terrestrial planets have been detected orbiting the star, a larger number than detected in any other planetary system. A study released in May 2017 suggests that the tightly packed exoplanets avoid colliding with one another due to orbits that are harmoniously resonant and, as a result, are stable for very long times.
