Tatooine-like Planet Discovered
ATP writes "CNN is reporting that a planet has been discovered in a solar system with 3 suns. The observation brings into doubt the theory stating that planets form from the dust orbiting around a single sun. The discovery also resulted in a new method of searching for extrasolar planets-- until now most searching focused only on single-sun systems."
This is not the planet we're looking for.

Don't let George Lucas see this. He'll want to change the next release of episode 4 and have Luke looking over 3 suns setting.

Come on... even google knows how many suns there are.

I guess the galaxy isn't so far away after all
Ask me about repetitive DNA
As noted by The Register, the planet is not in a galaxy far, far away, but a mere 149 light-year jaunt through our own Milky Way.
Might it be more like the planet in Pitch Black instead of Tattoine?
moo.
Would agriculture ever start? Would dwellings all be subterranean? Would concepts of work and play be utterly different? Religions would evolve differently. Would gender roles be affected?
Does anyone know of a work of science fiction that delves into this, in the way that The Left Hand of Darkness explored gender issues?

It's called nightfall and it's by Isaac Asimov. It's not one of his better works-- it has some neat ideas in it, but it was originally a short story that was later extended to novel length and as a result it feels rather stretched. Perhaps the original short story is better, I don't know (I've only read the novel).

From the article:
The planet, a gas giant slightly larger than Jupiter, orbits the main star of a triple-star system known as HD 188753 in the constellation Cygnus.
Unless I missed something major when watching the movies, Tatooine isn't a gas giant...
To me, Tatooine-like would be "that earthish desert planet", not "that gas giant with 3 suns"...
No love for Pitch Black?
Besides, Vin Diesel can kick Chewbacca's ass. He can do anything.
I like big butts and I cannot lie.
"Tatooine-like Planet Discovered," I read. Eagerly, I clicked the link. "They've found a way to tell just what the planet is like! Now that is news!"
Oh, but wait... It's actually a story about a planet that was discovered in a solar system with three stars. What in the hell does that have to do with making the planet "Tatooine-like"? That's like calling every other planet in our system "Earth-like".
*sigh*
With the exception of the one rock planet observed, ALL are gas giants and virtually all many times larger than all the Gas Giants in our own solar system combined. We are NOT talking something the size of Venus, here, we are talking something closer in size to our own sun. This does make a bit of a difference.
To directly observe a planet the size of Earth at a resolution of 1 pixel at a distance of 100 light-years would require a radio telescope with a 1 Km diameter. The proposed Km radio telescope array would do this. Nobody has such a telescope (yet) so nobody is making this sort of claim (yet). But it could be done, it has been designed and (last I heard) it was being built. Once it is finished, planetary discoveries will be made much more rapidly and much more reliably.
It is unlikely to happen in my lifetime, but such an array, in space, would be able to scan a lot of absorbtion frequencies, allowing you to not only detect such a planet, but know the composition of the atmosphere as well. A 1 mile diameter array in space would give you 6.25 pixels-worth of data - certainly enough to detect the existance of weather patterns and possibly enough to detect large moons (provided they are radio objects).
It's a small world and it smells funny; I'd buy another if it wasn't for the money; Take back what I paid (SoM)
Actually, it is somewhat surprising that a multi-star system would have a significant planet-forming debris cloud. Orbital mechanics tend to be relatively unstable in multi-star systems, so it's considerably more likely that the dust and debris would end up in unstable orbits and fall into one of the stars, instead of clumping up into a planet with a stable orbit. The fact that a planet can actually have a stable orbit in a system with three stars is actually somewhat surprising to me.
As for the system being thrown together after forming seperately, that's highly unlikely. First of all, space is mostly... well, space. The chances against two star systems colliding at all, nevermind doing so in a way that forms a stable three-star system are, no pun intended, astronomical. Even if a stable three-star configuration formed, it's even more likely that the sudden change in orbital dynamics would promptly eject the planet from the system (not hard to do--actually, if memory serves me, Mercury is in the process of being very slowly ejected from our own solar system. The sun will probably die first, though).
So, yes, lots of things could have happened... most of them probably even more fantastically implausible than the system forming as-is.
