English: This illustration depicts the three giant planets orbiting the Sun-like star Kepler 51 as compared to some of the planets in our solar system. These planets are all roughly the size of Jupiter but a very tiny fraction of its mass. NASA's Kepler space telescope detected the shadows of these planets in 2012–2014 as they passed in front of their star. There is no direct imaging. Therefore, the colors of the Kepler 51 planets in this illustration are imaginary.
