The Orlando Sentinel reports that Caltech planetary astrophysicist Konstantin Batygin and astronomer Mike Brown believe that “evidence is stacking up to prove” the existence of a planet roughly five to 20 times the size of Earth located past Neptune in the solar system. Batygin said that “five different lines of observational evidence” support the existence of Planet Nine, and that without such a planet, one “must come up with five different theories to explain them.” According to an article published by the scientists, the existence of a ninth planet is supported by the orbital angle of known Kuiper Belt Objects and the solar system’s known planets, as well as the presence of Kuiper Belt objects orbiting the sun in the opposite direction of the planets. Batygin said, “No other model can explain the weirdness of these high-inclination orbits. It turns out that Planet Nine provides a natural avenue for their generation. These things have been twisted out of the solar system plane with help from Planet Nine and then scattered inward by Neptune.” NASA has joined the search for the “elusive hypothetical planet by opening up images” from the Wide Field Infrared Survey Explorer (WISE) spacecraft. The ongoing “Bayards World: Planet 9” project uses tens of thousands of volunteers around the world to look for evidence in images taken from the spacecraft. (Image Credit: NASA)
