NASA's Kepler telescope spots four mysterious 'free floating' planets in deep space

NASA's Kepler Space Telescope spotted a number of 'free floating' planets in deep space. The telescope discovered four rogue planets with a similar mass to Earth. However, none of them were attached to our solar system.
