Scientists think that planets like Neptune might be super common!! Check out this Artist Concept of Neptune-mass exoplanets in the icy regions of planetary systems.
Beyond a certain distance from a young star, water and other substances remain frozen, leading to an abundant population of icy objects that can collide and form the cores of new planets. In the foreground, an icy body left over from this period drifts past the planet.
