Scientists believe they may have found a new planet in the far reaches of the solar system, up to four times the mass of Jupiter. Its orbit would be thousands of times further from the Sun than the Earth's - which could explain why it has so far remained undiscovered. Data which could prove the existence of Tyche, a gas giant in the outer Oort Cloud, is set to be released later this year - although some believe proof has already been garnered by Nasa with its pace telescope, Wise, and is waiting to be pored over. Prof Daniel Whitmire from the University of Louisiana at Lafayette believes the data may prove Tyche's existence within two years. He told the Independent: 'If it does, [fellow astrophysicist Prof John Matese] and I will be doing cartwheels. And that's not easy at our age.' He added he believes it will mainly be made of hydrogen and helium, with an atmosphere like Jupiter's, with spots and rings and clouds, adding: 'You'd also expect it to have moons. All the outer planets have them.' He believes the planet is so huge, it will ahve a raised temperature left from its formation that will make it far higher than others, such as Pluto, at -73C, as 'it takes an object this size a long time to cool off'. He and Prof Matese first suggested Tyche existed because of the angle comets were arriving, with a fifth of the expected number since 1898 entering higher than expected. However, Tyche - if it exists - should also dislodge comets closer to home, from the inner Oort Cloud, but they have not been seen. If confirmed, the status and name of the new planet - which would become the ninth and potentially the largest - would then have to be agreed by the International Astronomical Union. Currently named Tyche, from the Greek goddess that governed the destiny of a city, its name may have to change, as it originated from a theory which has now been largely abandoned. http://www.dailymail.co.uk/sciencet...che-believed-largest-planet-solar-system.html
Is this "Planet X" that people are talking about? If so, I wonder how long it would take for a spacecraft to get there? I suppose you could send it to rendezvous at the time the planet's orbit would move inside of Pluto's.
What? It's not the evil twin sister of earth, on the opposite side of the sun so we could never see it, with a diabolical equivelent to everybody here on earth waiting to do evil to our planet? What a letdown.
No this story is bullshit, there is absolutely no evidence of an extra planet. There are plenty of planetoids like Pluto though. http://mblogs.discovermagazine.com/badastronomy/2011/02/14/no-theres-no-proof-of-a-giant-planet-in-the-outer-solar-system/ http://www.space.com/10863-mystery-planet-tyche-debate.html
Here's an oddity. The Earth has (at least) two moons. The second is called Cruithne, and it orbits roughly the same orbit as the Earth, not around it.
Cruithne doesn't meet the criteria to be called a moon. It's an asteroid that orbits the sun, not earth.
Right there I knew I was reading BS. British papers love sensationalism. I've read that the possibility of anything bigger than Mars out there has been eliminated.
