A strange, distant world with three suns is baffling astronomers and challenging established theories.
The hefty planet is bigger than Jupiter although it stays very close to its main star; 20 times closer, in fact, than the Earth is to our Sun.

Some experts are puzzled because this intimate location should have stopped the body's formation.

"You shouldn't see it, but you do see it," German researcher Artie Hatzes told news@nature.com.

The planet, which is nestled within the triple star system known as HD 188753, lies 149 light-years from Earth in the Cygnus constellation.

Cool man. So what does that bring our planet count up to? I was watching the National Geographic channel last night and they said we had discovered 150 other planets outside of our own 9. Wonder how outdated the show was.

I think it's probably all a hoax. There probably are planets outside our solar system, although if there is a new planet in the solar system it will only have 1 sun, due to scientific research.

Dude this is a planet in another solar system. A Triple solar system. 149 LY from earth. Thats 875,000,000,000,000 miles away.

What I found most interesting is this planet should not be where it is, or the size that is is. It's too close to the suns (3 an additional oddity), and its to large to form that close to the primary sun.

Back to the drawing board on how solar systems are formed.

I feel that it only shows that there are still mysteries of the universe for us to unravel and understand. According to our (current) understanding of how planets are formed, it shouldn't exist....... yet there it is.

Has anybody even considered the possibility that the planet was captured by the multiple stars after it was formed somewhere else.

It seems like the first thing that should have been brought up.

Here's a little tidbit I picked up on this topic:

Quote:

The existence of a "hot Jupiter" planet in such a tight triple-star system poses challenging questions about how planets form. Theorists have long thought that hot Jupiters form much farther from their host stars and migrate into tight orbits through gravitational interactions with their circumstellar disks. But it's highly unlikely this could have happened in HD 188753. The disrupting gravitational influence of the secondary pair of stars would have truncated the disk around the primary, severely limiting the amount of available material to make a giant planet.

Theorists Alan P. Boss (Carnegie Institution of Washington) and Jack J. Lissauer (NASA/Ames Research Center) think the planet probably formed at a greater distance from its host star and was flung into its current orbit during complex gravitational interactions that should occur as multiple-star systems evolve from unstable to stable configurations. This game of cosmic billiards may have involved other stars that were once bound to HD 188753 and were subsequently ejected, or interloping stars in the crowded cluster environment.
