These Exoplanets are located outside of our solar system and orbit a star called TRAPPIST-1, which is classified as an ultra-cool dwarf. It has a lower temperature and lower mass than the Sun.
According to the NASA and the Belgian research team, these cluster of planets are less than 40 light-years away in the constellation Aquarius.
Scientists have said that they need to study the atmospheres before determining whether these terrestrial planets could support some sort of life or not. Two planets already show the signs of rocky in nature. There are no signs of puffy atmosphere.
