Scientists at the University of Montreal in Canada have found that two exoplanets that circle a red dwarf star could be composed of water to a large extent. The exoplanets are part of a planetary system located in the constellation Lyra, 218 light-years away from Earth.
The planets Kepler-138c and Kepler-138d, along with a smaller planetary companion, were discovered orbiting Kepler-138 in 2014 with the help of the National Aeronautics and Space Administration’s (NASA) Kepler Space Telescope.
Scientists believe that Kepler-138c and Kepler-138d are heavier than gas giant planets but lighter than rock worlds and a large fraction of their volume comprises water.

Some exoplanets orbit two stars at the same time, while some exoplanets do not orbit stars and are called rogue planets.
