WASHINGTON (Sputnik) — Three exoplanets resembling Earth have been discovered orbiting an ultra-cool dwarf star dubbed TRAPPIST-1, an international group of astronomers said in the interdisciplinary scientific journal Nature on Monday.
"We report observations of three short-period Earth-sized planets transiting an ultra-cool dwarf star only 12 parsecs away," the report stated.
The discovered planets, located about 40 light years away, reportedly have features similar to Earth, which means they could be habitable.
Scientists sometimes call these objects 'Goldilocks' planets because they're just the right distance from their host star to make life on them possible.
The three planets spotted in constellation Aquarius are also the first to be found orbiting an ultracool dwarf star, which was hard to find because it is small and faint.
