There may be a ninth planet after all!

Postby Bmat » Sun Feb 13, 2011 4:16 pm

If you grew up thinking there were nine planets and were shocked when Pluto was demoted five years ago, get ready for another surprise. There may be nine after all, and Jupiter may not be the largest.

The hunt is on for a gas giant up to four times the mass of Jupiter thought to be lurking in the outer Oort Cloud, the most remote region of the solar system. The orbit of Tyche (pronounced ty-kee), would be 15,000 times farther from the Sun than the Earth's, and 375 times farther than Pluto's, which is why it hasn't been seen so far.

It's an interesting article. It hasn't been proved that Tyche is there yet.

It's mine! I call dibs!

So...the proposed existence of Tyche was put forward to explain why many of the "long-period comets" of the Oort Cloud were coming from the wrong direction. The Oort Cloud itself still being only a hypothesis. Or has it been definitively proven?

A proposed planet to explain the discrepancies of the cosmological action of a hypothesized region of space that doesn't act the way the hypothesis says it should. Why am I getting flashbacks to Douglas Adam's "Rain God."

"I'm afraid I can't comment on the name Rain God at this present time, and we are calling him an example of a Spontaneous Para-Causal Meteorological Phenomenon."
"Can you tell us what that means?"
"I'm not altogether sure. Let's be straight here. If we find something we can't understand we like to call it something you can't understand, or indeed pronounce. I mean if we just let you go around calling him a Rain God, then that suggests that you know something we don't and I'm afraid we couldn't have that."
I'm going to die the way I've lived...poor, screaming, and naked.

Pluto was demoted unfairly, it is still the ninth planet in my book.

How can they be sure it's a planet? Maybe it's a whompin' big space ship. Or the Death Star. *cue ominous music*
