new planet in our solar system??

[Bill Verburg]

linky

no it's not a joke or porn link

[slakjaw]

I hope there are green chicks living there

[masraum]

I'll be really interested to see if this hunch pans out. Id think that a planet that large would have been spotted by now with all of the skywatching that's done around the world. But who knows, every year stuff that we thought we knew is proved wrong and stuff that we were previously ignorant of is discovered.

[slakjaw]

Like the existence of green chicks.

[Crowbob]

How could anything we were not ignorant of be discovered? Oh, I know. It could be discovered after we were not ignorant of it. (smiley)

Something that large must have a ginormous gravity field. How could it be out there and not f with the orbits of our solar system? Unless, of course, it is not in orbit around Sol but just a floating neighbor.

[slakjaw]

Maybe it's the mothership coming back for tabs?

[gtc]

O shi... it's UNICRON!

[tabs]

No No No..It is not going to be picking me up....Mother told me it is the planet that Obama is from, now we know where he is really from.......Planet Obama.

That article seems to point more towards a Brown dwarf star than a planet so no green chicks.

[scottmandue]

Are they sure it isn't Pluto?

[slakjaw]

Couldn't they have moved in when the star burnt out. They are pretty skinny so they must not eat much.

interesting

it appears the cozmic forces have decided to compensate us for the downgrade of Pluto

as mentioned in the article it could explain periodic asteroid/comet bombardments experienced by the Earth over it's history, every million years or so there has been a history of such events, by the way we are currently overdue.

Rings around Uranus.

I know I know, but somebody had to say it!

a star is any body that emits energy generated from thermonuclear reactions, a brown dwarf is just a very large Jupiter, they sometimes emit in the infrared due to gravitational contraction but they aren't big enough for fusion reactions, many have been found orbiting neighboring stars where they are close to the primary and cause noticeable perturbations in the primaries motions, if this proves out ours is so far out that it only affects the Oort cloud gravitationally the distances are staggering

here's a graph showing the current planetary distances from the Sun



To show the distance to Tyche you need another graph, notice that the distace from the Sun to Earth, Mars or any of the other planets out to Pluto at this scale is indistinguisable from zero, that's "far out man" (sorry, couldn't resist

[RWebb]

periodicity of mass extinctions is debatable (and is heavily debated)

Raup & Sepkoski proposed it in the mid-1980s; Fox performed a Fourier analysis about then & found a 26 Myr periodicity

there have been numerous other papers since & will likely be many more

if I had to bet, I'd bet yes

If there were green chicks, Kirk has already nailed them from the future.

I read somewhere scientists found basic amino acid chains in the ice of fallen asteroids. Hmm...
