  • Astronomers detect very Distant Object V774104 in our Solar System

Astronomers have detected a very distant object of interest in our solar system. It may in fact point towards other rogue planets that have been undetected up until now.

The most far away object in our solar system has been spotted by astronomers. This happens to be almost thrice removed from our earth than the planet Pluto. It is a small world and has been given the label V774104.

It has a dimensional volume of 500 by 1000 kilometers across its central axis. We will only know the details some 365 days from now. But till then we do have some preliminary information on the planet.

“We can’t explain these objects’ orbits from what we know about the solar system,” Scott Sheppard, an astronomer at the Carnegie Institution for Science in Washington, D.C., who announced the discovery here today at a meeting of the American Astronomical Society, told Sciencemag.

Its orbit remains to be pinned down. And it is an indicator towards other rogue planets that could lie on the far out periphery of our solar system. Such objects cannot have their orbital axes marked with ease. It is a difficult task indeed.

The discovery of this distant relative fragment in space marks a milestone in NASA’s repertoire of finding new astronomical objects that pique our imagination. And it lies at a distance of 15.4 billion kilometers from the sun. That is almost 103 astronomical units which is a substantial distance.

The fate of this planetoid of sorts could take one of two routes. If it comes close to the sun, then it could end up being in synch with the orbital axis of Neptune. However, if it does not wind up in close proximity to the sun, then it could up being the companion of Sedna and 2012 VP113.

These are also dwarf planets that don’t get too close to the sun. They are termed Inner Oort Cloud Objects. This label differentiates them from other icy Kuiper Belt fragments.

The eccentric orbits of these Inner Oort Cloud Objects make them pretty unique. At least so far there have been no explanations forthcoming regarding their nature as is to be judged from the laws prevailing in the solar system.

These planetoids carry scars and marks of whatever happened beyond the usual planetary activity in our solar system. Extreme examples of this kind are viewed with special telescopes having huge mirrors.

The Japanese Subaru Telescope which is installed in Hawaii was employed to see this far into space. It was a mission to find some of the strange and odd objects that encircle the conventional solar system we know about from our textbooks. With this novel knowledge our picture of the universe will be revised closer to home.
