Question: (CNN) You might have a replacement, Pluto. There could be another planet in our solar system. Researchers at the California Institute of Technology have found evidence in the outer solar system of an object that could be a real ninth planet. Nicknamed Planet Nine, it "has a mass about 10 times that of Earth and orbits about 20 times farther from the sun" than Neptune. That means "it would take this new planet between 10,000 and 20,000 years to make just one full orbit around the sun," according to Caltech. Researchers Konstantin Batygin and Mike Brown haven't actually seen the planet, but other research helped lead them to conclude that there is one. Basically, they found that certain objects in the Kuiper Belt -- the field of icy objects and debris beyond Neptune -- had orbits that peculiarly pointed in the same direction.Planet Nine has an orbit that's "about 20 times farther from the sun" than Neptune"We hope that other people are going to get inspired and start searching," researcher says 
 Question:Depending on where _ is in its "bizarre, highly elongated orbit," many telescopes have a shot at finding it.
