Both exoplanets orbit a star called Kepler-138 and were found in 2014. The observations at the time hinted that they were fairly different worlds from one another but that they were made largely of rock.
While the star was previously thought to have only three planets, these observations showed evidence of a fourth world. Including that extra planet in simulations of the system revealed that Kepler-138 c and d are far more similar than researchers initially thought.
Two Worlds Orbiting A Nearby Star Could Be More Than Half Water
Two worlds orbiting a tiny star 218 light-years away appear to be of a kind unlike anything we have in our Solar System.
The exoplanets are named Kepler-138c and Kepler-138d. Both are around 1.5 times the radius of Earth, and both appear to be soggy worlds consisting of thick, steamy atmospheres and insanely deep oceans, all wrapped around a rocky-metallic interior.

Two far-off planets are likely made of water , according to research conducted using NASA’s Hubble and Spitzer telescopes.
The so-called “water worlds” are orbiting a red dwarf star, the smallest and coolest kind of star, according to a news release from NASA’s Jet Propulsion Laboratory.
