Probable Rogue Planet Spotted
Maow writes with news of a sighting of a rogue gas giant: "'This object was discovered during a scan that covered the equivalent of 1,000 times the [area] of the full moon,' said study co-author Etienne Artigau of the University of Montreal. 'We observed hundreds of millions of stars and planets, but we only found one homeless planet in our neighborhood.' This planet appears to be an astonishingly young 50-120 million years old. The original paper is on the arXiv. Here's hoping the Mayan End-of-World-2012 people don't seize upon this as some kind of impending rogue planet on a collision course with Earth, but one can expect it'll be bantered about on such forums."
From the article: "The team believe it has a temperature of about 400C and a mass between four and seven times that of Jupiter - well short of the mass limit that would make it a likely brown dwarf."
can reach earth before they get too far?

Spotted it! Those puppeteers are going to have to come up with a new plan now, or give me one million stars to not reveal the secret.
It's a rogue planet!
we only found one homeless planet in our neighborhood
Either the galactic economy is going well, or they are good at hiding the problems.
Have they found Genesis? Genesis allowed is not! Is planet forbidden!
Tiller's Rule: Never use a word in written form that you've only heard and never read. You will end up looking foolish.
Given that the definition of a planet is dependent on the relationship between objects (planet and star, planet and moon, planet and other objects in the same orbit), how can something be classified as a type of planet if there are no observations of that object in relation to other objects in a planetary system?
Blish (who is completely out of favour as an SF writer - too intellectual) pointed out that drives which manipulate gravity or space need not be attached to a vehicle - they can just be attached to anything that you want to move. His "Cities in Flight" series describes whole commercial cities which specialise in specific services - often mining or refining - traveling the galaxy looking for work.
At one point a small planet is provided with propulsion in this way. Perhaps.....
First, in the summary you forget to identify the distance: 100ly. Well, that pretty much rules out any worry of a collision even if at such a distance the alignment would be astronomically unlikely to be one which would allow for a collision.
Second, why does anyone care if there is a 'spike' in discussion with the 2012 doomsayers? You think there WOULDN'T be a spike in discussion around December 2012? And who cares if there is? The good news, is that by January, all the 2012 end of the world nonsense will be over (Even if they are right ;) )
My problem isn't any of that however. My problem is THIS travesty from the article:
One tricky part is determining if rogue planet candidates are as massive as the "failed stars" known as brown dwarfs, further along in stellar evolution but without enough mass to spark the nuclear fusion that causes starlight.
It's so freaking wrong I can't even parse it to bitch about it in any specific manner. And to me, that's the worst thing that could happen. If I can't complain, I don't want to live on this planet anymore.
Out of modpoints but really liked a post? 1BDkF6TtmmeZ3yqXbz9yhdYVqRYnwFoXDj
prediction of the end of the world all you want. But on the next day you must promise to never, ever, talk about the end of the world.

Rogue planet all by its lonesome?
Let's name it Han Solo.
Let me know when they discover a nethack planet.

The good news: It is 100 light years away from Earth so there's no way for it to reach us in time.
The not so good news: 100 light years is nothing cosmic-distance-wise. If our detection capabilities can let us spot a Super-Jupiter sized object 100 light years away, are there smaller object that are closer, but still pose a threat? This is completely unrelated to the Mayan Apocalypse nonsense. We should improve our detection abilities mainly to spot asteroids headed our way in time to prevent a catastrophe.

Of the two possible origins of planets like this, the first would be that it's a star that didn't get enough mass to ignite. This seems to make the most intuitive sense to me.
The other possibility is that it was somehow ejected form it's parent star. This seems less likely, but then I'm not an astrophysicist. What would it take to eject a planet that large from it's solar system?
What kind of event would it take to say, eject Jupiter? Would it take a huge rogue Nemesis kind of star, or could something smaller perturb it's orbit just enough to eject it?
Assuming it was ejected, could you not interpolate from the planets velocity just where it came from, work backwards to find it's old parent star, and perhaps even figure out what other stellar body it interacted with that caused the planet to be ejected?

LocalRoger wrote several shorts based in this universe. I though they were great, and am still waiting for a book.
Final Yamato Main article: Final Yamato Premiering in Japanese theaters on March 19, 1983, Final Yamato reunites the crew one more time to combat the threat of the Denguilu, a militaristic alien civilization that intends to use the water planet, Aquarius, to flood Earth and resettle there (having lost their home planet to a galactic collision). Captain Okita, who was found to be in cryogenic sleep since the first season, returns to command the Yamato and sacrifices himself to stop the Denguili's plan. Susumu and Yuki also get married. The story is set in the year 2203, contradicting earlier assumptions that its predecessor, Yamato III, took place in 2205. Having a running time of 163 minutes, Final Yamato retains the record of being the longest animated film ever made.

Great. Just great. Homeless planets orbiting around the neighborhood, pushing a giant shopping cart, talking to themselves, collecting cans, hanging around stoplights washing windows... Shit. There goes the neighborhood.
The year: 2014. From out of space comes a runaway planet, hurtling between the Earth and the Moon, unleashing cosmic destruction! Man's civilization is cast in ruin!
Two thousand years later, Earth is reborn...
A strange new world rises from the old: a world of savagery, super science, and sorcery. But one man bursts his bonds to fight for justice! With his companions Ookla the Mok and Princess Ariel, he pits his strength, his courage, and his fabulous Sunsword against the forces of evil.
He is Thundarr, the Barbarian!
We better all keep our eyes on it, it's already rogue, you never know if it might get all mavericky on us.
you know someone's gonna say it
in the subject line is confusing and annoying. We need a "-1 poor communication skills" mod option! :)
Sounds like something right out of Space 1999, which was considered very pseudoscience.
Mongo! Ming is coming!

It's heat from the planet's formation. It's estimated to require about 12 Jovian masses to start ignition, and this is only 4-7 Jovian masses.
Do what thou wilt shall be the whole of the Law
...I'm holding out for the Shaman planet.
Off the top of my head -- heat of accretion, radioactive decay, partial nuclear ignition delaying cooling, tidal heating from it's previous orbit before it was ejected, . . .
But that's all speculation rather than applicable knowledge.
Put my fist through my alarm clock with its ding-dong death inside my ear. - The Blackjacks.
What's keeping it at 400C? Or is it almost a brown dwarf - though Jupiter doesn't get to that sort of temperature on my understanding.
Planet X...... The X stands for the unknown as to where it came from and where it is going. But when we figure that out it won't be Planet X anymore. It will be Planet With a plan.
Orphan sounds more appropriate than rogue. Rogue is like it's out to do some damage, which is mathematically not very feasible for it anyway.
Yeah, we should stop anthropomorphising planets. They get really upset by it.
