Newly Found “Ice Ball” Planet Is the Same Mass as Earth

Using NASA’s Spitzer Space Telescope and Korea Microlensing Telescope Network, scientists have discovered an exoplanet that is the same mass as Earth. Even though the planet orbits around its star at the same distance as Earth orbits the Sun, it is too cold to host life. The newly found “ice ball” planet is about 13,000 light-years away from our planet.
