dark world possibly hiding within our solar system "If there's going to be another planet in the solar system, I think this is it," Greg Laughlin of the University of California, Santa Cruz told National Geographic.
"It would be quite extraordinary if we had one. Fingers crossed. It would be amazing." If the planet exists, it is thought to be about ten times as massive or three times as large as Earth. That sort of sized planet occurs throughout the universe but has been an obvious omission from our own. "This would be a real ninth planet," says Brown, the Richard and Barbara Rosenberg Professor of Planetary Astronomy. "There have only been two true planets discovered since ancient times, and this would be a third. It's a pretty substantial chunk of our solar system that's still out there to be found, which is pretty exciting." It would pandora on sale be around 200 to 300 times as far away from the sun as pandora charms australia cheap we arewhen it gets closest to the star, scientists say. It will spend some of its time as much as four times as far away as that, and an entire orbit of pandora jewlry the sun probably takes about 20,000 years. The planet might have made its way out to the edge of the solar system when it was thrown out there by the gravity of Jupiter or Saturn, the scientists suggest. At such distances, the planet could be impossible to spot even with the two huge telescopes that are currently looking for it. So little light is sent back from that far away that it might never make it back for us to see. It is surrounded by much brighter lights even the distant Pluto could be about 10,000 times brighter and so scientists have to be sure that they point telescopes at exactly the right point and pick out an already very unlikely speck of light. That's why the scientists have spotted the potential planet by seeing the disturbances that it is causing in the gravitational field of the far star system. The solar system doesn't often change. The only recent addition was Pluto, which was found in 1930 and spent most of the 21st century as its most distant and smallest planet until it was controversially downgraded to being just a dwarf planet, and the solar system went back to having eight members. If the new planet is real, then it will definitely be a planet, scientists say. Since it dominates a bigger region than any of the other planets, it would "the most planet pandora bracelet gold y of the planets in the whole solar system", Brown said. The downgrading of Pluto was partly the result of work by astronomer Michael Brown, who co wrote the new paper. He had found that Pluto was surrounded by a huge number of similarly sized planets, and the International Astronomical Union decided that Pluto would be excluded from a new definition. The two astronomers found the new potential planet while they were looking at those small rocks. They seemed to fly around on orbits that couldn't be happening by chance, and instead were best explained by a big ninth planet sitting out there with them. A ninth planet has long been hypothesised and become the basis of some conspiracy theories originally going under the name Planet X. It was first talked about more than a century ago, and looking for that planet was what brought astronomers to find Pluto.
