A nearby solar system with seven Earth-sized planets has been discovered by astronomers, three of which have the possibility of liquid water because of their proximity to the star they're orbiting. The star, known as TRAPPIST-1, is a small, dim celestial body in the constellation Aquarius, with the seven planets passing around it once every two to nine days.
