Kepler 1647-b bigger than Jupiter, circles two stars... just like Tatooine

A team of astronomers led by NASA have discovered the largest circumbinary planet on record, according to the American Astronomical Society.

It also has the longest orbit of any circumbinary planet, Kepler 1647-b takes 1107 days - over three years - to run a lap around its stars.

Despite its bulk, however, it took astronomers three years to confirm its planetary status due to its long orbital period, and was only spotted by the telescope on board the Kepler spacecraft twice over its mission's lifetime.

Laurence Doyle, co-author of the paper and a research scientist at the Search for Extraterrestrial Intelligence SETI institute, was the first to notice a foreign object cruising across the binary star system back in 2011.

Circumbinary planets can be tricky to model as the binary stars are circling each other whilst the planet is transiting, so no two transits are the same.

Kostov, said he hoped to "use the results from Kepler to predict circumbinary planet discoveries from TESS a new NASA exoplanet mission to fly next year , then go and find them."

Astronomers have spotted a planet 8,000 light-years away

Several planets have been documented

as revolving around two or more stars, but this is the first time

one has been observed thanks to the bending of light.

The so-called "circumbinary planet" — called OGLE-2007-BLG-349 —

was first discovered in 2007 and was believed to be orbiting one

A team of astronomers from NASA s Goddard Space Flight Center and San Diego State University has discovered a new exoplanet that orbits around two stars.

At 4.4 billion years old, Kepler-1647b is about the same age of the Earth.

With this strategy, astronomers look for dips in brightness from the host star as a planet transits in front of it in relation to the Earth.

However, Kepler-1647b s orbital period is so long that it transits in front of its star less frequently than other confirmed exoplanets.

It then took several years of analysis to confirm that the dip in brightness noticed in Kepler data was indeed caused by a circumbinary planet.

The transits are not regularly spaced in time and they can vary in duration and even depth.

Astronomers have discovered the largest planet ever to orbit a double-star system.

Planets that orbit two stars, often known as Tatooine planets first got their nickname in the Star Wars films when Luke Skywalker witnessed a twin sunset when he returned to his home world.

Scientists at San Diego State University made their findings using the Kepler Space telescope and presented them to the American Astronomical Society this week.

But it has taken five years to confirm his suspicions.

The planet is 3,700 light years away and around the same age as the earth at 4.4 billion years old.

A team of astronomers from NASA s Goddard Space Flight Center and San Diego State University has announced the exciting discovery of a planet with two suns within the Cygnus Constellation, using the Kepler Space Telescope.

Named Kepler-1647 b, the planet is located 3,700 light years from Earth, and thought to be similar in age to our planet, around 4.4 billion years old.

The team wrote on the SDSU website that it takes the planet about 1,107 days, or a little over three years, to orbit its host stars.

The transits are not regularly spaced in time and they can vary in duration and even depth, he said.

According to the team, Laurance Doyle, a coauthor on the paper and astronomer at the SETI Institute, noticed a transit back in 2011.

Additional support from amateur astronomers in the KELT Follow-Up Network aided the team in assessing the planet s mass.

The Star Wars universe is packed with evocative locations, from the desert planets of Tatooine and Jakku in The Force Awakens, to the frozen environs of Hoth, the Cloud City of Bespin, the entrancing lakes of Naboo and the volcanic nightmare of Mustafar.

Tatooine's binary suns in A New Hope - Kepler-16b

"If there's a bright centre to the universe, you're on the planet that's farthest from," says Luke Skywalker in A New Hope.

Actually, it's our solitary Sun that's the odd one out here; astronomers reckon that about 80% of stars are multiple-star systems, which means that worlds with two, three or even seven sunsets are the norm.

Multiple star systems are everywhere you look; next time you're outside in clear night skies, look north to find the second star in from the tip of the handle of the Plough/Big Dipper and you'll notice that it's an obvious double star.

However, the bigger star Mizar is actually four stars while smaller star Alcor is two, all gravitationally bound.
