Is a Massive Hidden Planet At the Edge of the Oort Cloud Hurtling Comets Towards Earth?

Our sun may have a stealth companion that disturbs comets from the edge of the solar system — a giant planet with up to four times the mass of Jupiter, researchers suggest. A NASA space telescope launched last year may soon detect such a stealth , if it actually exists, in the distant icy realm of the comet-birthing Oort cloud, which surrounds our solar system with billions of icy objects. The potential giant Jupiter would likely be a world so frigid it is difficult to spot, researchers said. It could be found up to 30,000 astronomical units from the sun. One AU is the distance between the Earth and the sun, about 93 million miles.

The giant planet is hidden in our Solar System according to scientists John Matese and Daniel Whitmire, from the University of Louisiana at Lafayette. According to the team, a colossus called Tyche is hidden in the Oort Cloud—the asteroid beehive that forms the outer shell of our home system, one light-year in radius. They claim that data already captured by NASA's Wide-field Infrared Survey Explorer proves its existence.

Matese and Whitmire are convinced that Tyche composed mostly of hydrogen and helium is very real orbiting 15,000 times farther from the Sun than Earth, orbiting the Sun with moons and rings  and an athmosphere with clouds and storm systems similar to Jupiter with a mild temperature (-73ºC/-99.4ºF).
 
If Tyche's existence is confirmed, its Solar System planet status may not be debated that Tyche could be a planet born in another star system and captured by ours.

Not sure about that. When I looked up the Oort Cloud on Wikipedia, it said it's supposed location was about one lightyear away (1/4 the distance to Proxima.) If a sphere does exist on that scale and at that distance, it seems to me that it would have to be comprised of fairly small chunks of rock in order to hold its orbit. If the chunks of rock collided and gained sufficient mass, they would break from Sol's gravity. If they were too small or moving too slow, they'd fall into the solar system as meteors (which they may well do.) Also, if they sped up (say, through an impact and an exchange of energy) the one that sped up would escape it's tenuous orbit, and the one slowed down would fall in a spiral towards the sun. I just can't imagine a cloud of that magnitude, that far away from it's center of gravity, continuing to exist for all these thousands of eons since the solar system was formed.

Very odd that the Sumerians also mention this.

@Alex I think you're underestimating the possible size of the Oort cloud and the combined gravity.

This would most likely not be a planet if found, but rather a brown dwarf, basically a small star that hasn't ignited because its so cold, but still made of gas.

A very cool idea. But who said they can name it? First you discover it THEN you name it. Until it's actually discovered it gets some NASAesque designator like "Oort Cloud Anomaly #1/OCA1" or some such. No fair coming up with a name before it's found. First, catch thee thy rabbit....

Besides, "Tyche" is too close to "Tycho," which is both an astronomical feature already (Lunar crater) and the name of a major toy company.

If I find it first, I'm going to name it Algore: it's gaseous, cold, icy, way out there, and given the potential damage it could do to Earth through unforeseen consequences, it would be better if it didn't have any actual ability to affect the local environment.

It's a nice place to share my thoughts.good,i like it.

Aren't most star systems binary?

Omg, Richard! You just made my week with that!

I was just reading an article this morning in the book "Forbidden Science" (www.atlantisrising.com) that speculates that our solar system may well be a binary system. Jeremy could be correct in saying that this object would not be a planet but rather a brown dwarf.

A brown dwarf isn't a star. It was said "basically a small star that hasn't ignited" - but if it hasn't ignited it isn't a star.

Hi there.. It's now September 2011. This TYCHE is parked right in our solar system.. It's been known about for millennia. Myan, somerians, Egyptions,and now it's hear, I recon within days now, it will rise from it's hiding place, and show the whole planet that it alually exists..
Now the question is what we do about the conditions it brings along with it..
It's masive 4 times the size of Jupiter, now let's think about this gas giant, we all know it's there and the effect it has on our small space we take up..
Q. Why have all the rings on this masive planet moved to the northern hemisphere,????
We all see Saturn and know of her moons..
Q. Where have the massive ice giant moons gone..???
Our sun. Solar flares every where. We see the effects that they have on us...
Q. Why has NASA.. Put a square box on the suns videos..???.
Something is happening.. Our solar system is being invaded so why not come clean...

It is brilliant that we are starting to find planets around other stars and still have so much trouble finding stuff that's (in space terms) right beside us.
