Scientists are not sure about Planet 9’s location yet, but they think it’s located just behind Neptune (planet 8).
About 6 months ago, you would count the solar system having 8 planets plus our own star, the Sun. But think again. A man called Mike Brown is one who would say “no!” Mike, from the California Institute of Technology, is very interested in looking beyond these 8 planets. “There’s this huge part of the solar system that we’re only just beginning to learn about”, Mike says.
Only a bit beyond Neptune is an area of space called the Kuiper Belt which scientists thought was empty only a few years ago. In fact, it is the home to icy rocks and objects and billions of comets. There are also a few dwarf planets such a Pluto. Mike and his workers are convinced that all evidence they have proves that planet 9 exists in space but that it will take several years to find it completely.
