The evidence for Planet Nine was unveiled by Caltech scientists Mike Brown and Konstantin Batygin at the California Institute of Technology in Pasadena, California. The duo used mathematical models and computer simulations to map out Planet Nine's orbit after spotting a strange alignment in the orbits of six other Kuiper Belt objects. The orbits of those smaller objects lined up in a way that suggested the gravitational influence of another much more massive object, which Brown and Batygin dubbed ''Planet Nine''.
This planet is about 10 times the mass of the Earth. It would take the planet between 10,000 and 20,000 years to orbit the sun. Its orbit is about 20 times farther from the sun than that of Neptune.
It hasen't been observed or photographed yet, but hope other astronomers will search for it.
