A planet with two suns ... something straight out of Star Wars

In a press release seemingly from a science fiction movie, a recently discovered planet about 200 light years from Earth reportedly orbits two different suns.  This is the first time researchers have witnessed a planet with two stars, but researchers aren't surprised at this discovery.    

The Kepler 16b planet has two suns that orbit one another in 35 days.  If a person visited Kepler 16b, they would be greeted by a sky that featured two prominent stars -- and circles both stars in 229 days.  

SETI researchers don't believe that life exists on Kepler 16b, but are anxious to learn more about Kepler 16b.  The planet itself likely is extremely dense, and is close to the size of Saturn, researchers say.

Kepler 16b's larger sun is almost 70 percent the size as the Earth's sun, while the smaller star is closer to 20 percent.  The planet and its celestial bodies are able to form a proper system because they are an appropriate distance from one another, so there doesn't appear to be a risk of the planet collapsing into one of its stars.

When Tatooine was first shown in Hollywood, there was immediate doubt as to whether or not a similar planet would be found.  

"It's possible that there's a real Tatooine out there," said John Knoll, Industrial Lights and Magic visual effects supervisor, in a statement.  "Kepler 16b is unambiguous and dramatic proof that planets really do form around binaries."

The findings were published in Science, and were made using the Kepler space telescope.  The Kepler program aims to continue searching for planets similar to Earth that also orbit stars, along with studying how many stars have bodies currently orbiting them.

Well, according to the limited material we have here, we only know one star is 20% our Sun's size and the other is 70%. That tells us little about mass. We know that the period for the planet is 227+ days. However, after checking with NASA:

http://kepler.nasa.gov/Mission/discoveries/kepler1...

I discover the article is poorly written. That 70% and 20% actually refer to mass, not size (size could mean either but it needs to be clearer). So, now that we know we aren't dealing with a neutron star here, I'd of first assumed it would be circular with some deviation.

NASA makes it easy though, as we don't have to assume. Play with that diagram a little and you'll see for yourself. It looks pretty circular to me. What's curious is that there is a planet hypothesized even closer than this one they found which has a less than perfect orbit. However, there is a little bit of wobble on the horizontal plane per the diagram for the found planet which would make sense considering the two graviational fields it is dealing with. Also interesting is the second star's orbit looks pretty stable.

With that being settled let's go have some blue milk and then head over to Toshi station to pick up power converters...

Those in the know say it was Wookie milk.
