Ever since then, astronomers have been surveying the skies in hopes of tracking it down.<\/p>\n<p>Among those astronomers are Scott Sheppard of the Carnegie Institution for Science and Chad Trujillo of Northern Arizona University. They were on the discovery team for 2012 VP113. Now they\u2019re part of a team conducting a survey using instruments such as the Dark Energy Camera on the NOAO 4-meter Blanco telescope in Chile and the Japanese Hyper Suprime Camera on the 8-meter Subaru telescope in Hawaii.<\/p>\n<p>So far the survey has covered nearly 10 percent of the sky.<\/p>\n<p><iframe id=\"twitter-widget-0\" scrolling=\"no\" frameborder=\"0\" allowtransparency=\"true\" allowfullscreen=\"true\" class=\"\" style=\"position: absolute; visibility: hidden; width: 0px; height: 0px; display: block; flex-grow: 1;\" title=\"X Post\" src=\"https:\/\/platform.twitter.com\/embed\/Tweet.html?creatorScreenName=b0yle&amp;dnt=true&amp;embedId=twitter-widget-0&amp;features=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%3D%3D&amp;frame=false&amp;hideCard=false&amp;hideThread=false&amp;id=770410547166732288&amp;lang=en&amp;origin=https%3A%2F%2Fwww.geekwire.com%2F2016%2Fsearch-planet-nine-turns-three-mini-planets%2F&amp;sessionId=3cebb4bfe3bdd22199ff7c364452cfe49afe3464&amp;siteScreenName=geekwire&amp;theme=light&amp;widgetsVersion=6a3ad42b224df%3A1778106238597&amp;width=550px\" data-tweet-id=\"770410547166732288\"><\/iframe><\/p>\n<blockquote class=\"twitter-tweet\" data-width=\"550\" data-dnt=\"true\" data-twitter-extracted-i1782804223143951617=\"true\">\n<p lang=\"en\" dir=\"ltr\">.@CarnegiePlanets&#8217; Scott Sheppard is 80% sure #PlanetX exists says we&#8217;ll know for sure w\/in 2 yrs https:\/\/t.co\/ioPYwEWONc via @SPACEdotcom<\/p>\n<p>\u2014 Carnegie Science (@carnegiescience) August 29, 2016<\/p>\n<\/blockquote>\n<p><script async=\"\" src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><\/p>\n<p>https:\/\/twitter.com\/RonBaalke\/status\/770458047814574080<\/p>\n<p>Sheppard and Trujillo identified several&nbsp;previously unknown objects and have submitted their coordinates to the International Astronomical Union\u2019s Minor Planet Center for official designations. A paper on the discoveries has been accepted for publication in the Astronomical Journal.<\/p>\n<p>The list includes these&nbsp;mini-worlds:<\/p>\n<ul>\n<li>2014 SR349, which is in the kind of extreme orbit that could hypothetically have been perturbed by Planet Nine.<\/li>\n<li>2013 FT28, which isn\u2019t quite as much in the sweet spot for Planet Nine action, dynamically speaking.<\/li>\n<li>2014 FE72, which is said to be the first identified object from the faraway Oort Cloud with an orbit entirely beyond Neptune. The orbit is stretched out far enough to take it more than 3,000 times farther away from the sun than Earth is. The astronomers say its orbital path seems likely to be influenced by gravitational forces beyond the solar system, such as passing stars or the galactic tide.<\/li>\n<\/ul>\n<p>The orbits that have been mapped so far aren\u2019t sufficient to solve the planetary mystery. Planet Nine&nbsp;may be so dim and so far away that it\u2019ll remain hidden until next-generation telescopes come into play. And there\u2019s still the possibility that it doesn\u2019t exist, which means some other phenomenon would have to explain the weird orbits of objects like Sedna, 2012 VP113 and 2014 SR349.<\/p>\n<p>\u201cRight now we are dealing with very low-number statistics, so we don\u2019t really understand what is happening in the outer solar system,\u201d Sheppard said in a news release. \u201cGreater numbers of extreme trans-Neptunian objects must be found to fully determine the structure of our outer solar system.\u201d<\/p>\n<p>Even if Planet Nine isn\u2019t found, the search should shed further light on the farther reaches of the&nbsp;solar system. And that, figuratively speaking, is truly far out.<\/p>\n<figure id=\"attachment_270766\" aria-describedby=\"caption-attachment-270766\" style=\"width: 630px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full-width wp-image-270766\" src=\"https:\/\/cdn.geekwire.com\/wp-content\/uploads\/2016\/08\/160829-solar-system-distant-630x276.jpg\" alt=\"Far-out orbits\" width=\"630\" height=\"276\" srcset=\"https:\/\/cdn.geekwire.com\/wp-content\/uploads\/2016\/08\/160829-solar-system-distant-630x276.jpg 630w, https:\/\/cdn.geekwire.com\/wp-content\/uploads\/2016\/08\/160829-solar-system-distant-768x336.jpg 768w, https:\/\/cdn.geekwire.com\/wp-content\/uploads\/2016\/08\/160829-solar-system-distant.jpg 960w\" sizes=\"(max-width: 630px) 100vw, 630px\"><figcaption data-nosnippet=\"\" id=\"caption-attachment-270766\" class=\"wp-caption-text\">This diagram highlights the orbits of three newfound worlds, plus a potential orbit for the yet-to-be-discovered object known as Planet X or Planet Nine.
