Largest planet in the solar system could be about to be discovered (4x Jupiter)

Largest planet in the solar system could be about to be discovered (4x Jupiter)

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.

A new world? Astronomers believe a huge gas giant may be within the remote Oort Cloud region

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 a have 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'.

Isolated: The Oort Cloud, where Tyche is believed to be, is a sphere with a radius of one light year

Now if this is confirmed it will be a planet. Dont care if it has a weird orbit around our star. Twisted Evil

Daily Mail is not a reliable source.

For a more reasoned take on it, see the Bad Astronomy blog. In short, no particularly strong reason to believe this object is out there.

Now if this is confirmed it would be a brown dwarf. Don't care about it not being massive enough to do deuterium fusion Twisted Evil

Groan.

Don't we see the same story every six months? Just with different values for the mass?

So much for Tyche, Nemesis and other giant "Planet X"...

NASA: NASA's WISE Survey Finds Thousands of New Stars, But No 'Planet X'

No undiscovered Saturns out to 10000 AU, no undiscovered Jupiters out to 26000 AU.

No gas giants out there to be sure, but there is no evidence of a lack of smaller objects that would no doubt make Mike Brown very happy.
