Astronomers found a new solar system just 39 light years from ours, full of Earthlike planets. (Jenny Starrs,Sarah Kaplan/The Washington Post)A newfound solar system just 39 light-years away contains seven warm, rocky, Earthlike planets, scientists say. But even if we don't, whatever we find will be super-interesting.”The newly discovered solar system resembles a scaled-down version of our own. Instead of three planets, TRAPPIST-1 had seven, renamed TRAPPIST-1b through -h in order of their distance from the star. This chart compares the amount of heat energy received by the planets of TRAPPIST-1 system to that of the planets in our solar system.
