A “planet” that is the size of Neptune is lurking on the outer reaches of the Solar System. It revolves around the Sun once in 15,000 years. Very early on in the formation of the Solar System, the planet went out of the close orbits and stayed at the periphery of the Solar System.New Planet 10 Times Earth's Mass Lurks Beyond Pluto - Orbits Once in 15,000 years! #Space Click To Tweet
The Caltech scientists – Konstantin Batygin and Mike Brown – have found this planet with the mass of 10 Earths.
Batygin and Brown inferred its presence from the peculiar clustering of six previously known objects that orbit beyond Neptune. They say there’s only a 0.007% chance, or about one in 15,000, that the clustering could be a coincidence. Instead, they say, a planet with the mass of 10 Earths has shepherded the six objects into their strange elliptical orbits, tilted out of the plane of the solar system.
The orbit of the inferred planet is similarly tilted, as well as stretched to distances that will explode previous conceptions of the solar system. Its closest approach to the sun is seven times farther than Neptune, or 200 astronomical units (AUs). (An AU is the distance between Earth and the sun, about 150 million kilometers.) And Planet X could roam as far as 600 to 1200 AU, well beyond the Kuiper belt, the region of small icy worlds that begins at Neptune’s edge about 30 AU.
Earlier such claims have been found out to be bogus. But the duos studies have been peer-reviewed and found to be plausible. If their research world, we could find more objects lurking around in that orbit.
