An astrophysicist says it's likely that an as-yet undiscovered planet exists on the dark fringes of our solar system, messing with the orbits of celestial bodies in the Kuiper Belt, just beyond Neptune. Rodney Gomes says the new planet could be anywhere from half to four times the size of Earth and is likely a rogue planet that floated over from another solar system. Other space scientists say Gomes' findings may be a lot of hot air and aren't sure his calculations support his theory. now.msn.com... An as yet undiscovered planet might be orbiting at the dark fringes of the solar system, according to new research. Too far out to be easily spotted by telescopes, the potential unseen planet appears to be making its presence felt by disturbing the orbits of so-called Kuiper belt objects, said Rodney Gomes, an astronomer at the National Observatory of Brazil in Rio de Janeiro. Kuiper belt objects are small icy bodies—including some dwarf planets—that lie beyond the orbit of Neptune. Once considered the ninth planet in our system, the dwarf planet Pluto, for example, is one of the largest Kuiper belt objects, at about 1,400 miles (2,300 kilometers) wide. Dozens of the other objects are hundreds of miles across, and more are being discovered every year. What's intriguing, Gomes said, is that, according to his new calculations, about a half dozen Kuiper belt objects—including the remote body known as Sedna—are in strange orbits compared to where they should be, based on existing solar system models. (Related: "Pluto Neighbor Gets Downsized.") The objects' unexpected orbits have a few possible explanations, said Gomes, who presented his findings Tuesday at a meeting of the American Astronomical Society in Timberline Lodge, Oregon. news.nationalgeographic.com... How big exactly the planetary body might be isn't clear, but there are a lot of possibilities, Gomes added. Based on his calculations, Gomes thinks a Neptune-size world, about four times bigger than Earth, orbiting 140 billion miles (225 billion kilometers) away from the sun—about 1,500 times farther than Earth—would do the trick. But so would a Mars-size object—roughly half Earth's size—in a highly elongated orbit that would occasionally bring the body sweeping to within 5 billion miles (8 billion kilometers) of the sun. Gomes speculates that the mystery object could be a rogue planet that was kicked out of its own star system and later captured by the sun's gravity.

Originally posted by Just Chris But the article doesn't once mention that it may or may not be Nibiru, just a rogue planet with a size similar to Pluto. Doesn't exactly fit NIBIRU descriptions. With that in mind however, will be interesting to see what comes of this?

Na rubu našeg Sunčevog sustava mogao bi postojati do sada neotkriven veliki planet, objavio je prošli tjedan na konferenciji u SAD-u brazilski astronom Prema proračunima znanstvenika, nepoznati svijet kruži toliko daleko da ga teleskopi ne mogu vidjeti. No njegova gravitacija utječe na orbite objekata u tzv. Kuiperovom pojasu koji se proteže daleko iza orbite Neptuna, a u kojem kruže malena ledena tijela, među kojima i neki patuljasti planeti. Jedan od najvećih svjetova Kuiperova pojasa je patuljasti planet Pluton promjera 2.300 km. Svake godine u njemu se otkriju nova tijela među kojima je do sada zabilježeno desetak s promjerom većim od stotinu kilometara. Rodney Gomes , astronom iz Brazilske nacionalne promatračnice u Rio de Janeiru, prošli je tjedan na konferenciji Američkog astronomskog društva u Timberline Lodgeu u Oregonu objasnio da njegovi novi proračuni pokazuju kako se nekoliko tijela Kuiperova pojasa, među kojima i daleka Sedna, kreće po neobičnim putanjama koje ne odgovaraju postojećim modelima. Prema Gomesu, ovakve anomalije imaju nekoliko mogućih objašnjenja, međutim, najjednostavnije je da u udaljenim mračnim područjima Sunčeva sustava postoji neko veće tijelo koje svojom gravitacijom utječe na objekte u Kuiperovu pojasu. U svojoj studiji Gomes je analizirao orbite 92 poznata objekta pojasa i rezultate usporedio s računalnim modelima koji predviđaju kako bi izgledao njihov raspored sa i bez dodatnog planeta. Ako udaljeni svijet ne postoji, modeli ne mogu objasniti zašto su orbite šest tijela u Kuiperovom pojasu tako jako izdužene. Koliko bi velik misteriozni planet mogao biti, još uvijek nije jasno, no postoji više mogućnosti. Prema Gomesovim kalkulacijama, jedno rješenje enigme mogao bi biti planet veličine Neptuna, odnosno četiri puta veći od Zemlje, koji kruži na 225 milijardi km od Sunca (oko 1.500 puta dalje od Zemlje). Prema drugom, to bi moglo biti tijelo veličine Marsa (oko pola veličine Zemlje) koje se kreće po vrlo izduženoj orbiti, pa povremeno dođe na 'samo' osam milijardi kilometara od Sunca. Gomes smatra da bi nepoznati svijet mogao biti planet lutalica koji je davno izbačen iz sustava svoje matične zvijezde da bi ga konačno zarobila gravitacija Sunca. Također postoji mogućnost da je nastao negdje bliže Suncu, ali je kasnije gravitacijskim utjecajima drugih planeta izbačen na periferiju našeg sustava. Ako planet postoji, njegovo će otkrivanje biti veliki izazov. Prije svega njegov sjaj je vjerojatno previše slab da bi se izravno vidio teleskopima. Osim toga, teško je predvidjeti gdje bi se mogao nalaziti, pa znanstvenici ne znaju ni kamo bi usmjerili svoje teleskope. Gomesovi kolege smatraju da su novi proračuni vrlo intrigantni, međutim, smatraju da je do konačnog zaključka da planet postoji još dug put. - Sviđa vam se članak?
