A team of American astronomers discovered by NASA’s Kepler telescope within a binary star system very similar to the famous Star Wars film series.
Such binary star systems are of paramount importance to current science fiction fans, especially since the Tatooine, the home planet of Luke Skywalker character orbiting binary stars Unie.
The new planet, named Kepler-47 was and is located in the constellation Cygnus, about 5,000 light years from Earth. It consists of a pair of stars that pass near each other at an interval of 7.5 days. A star is like the sun, while the other reaches only one third of its pocket size and emits 175 times less light.
Around these inner planet orbiting a star whose diameter is three times larger than the Earth, and another outer planet that is slightly larger than Uranus.
Inner planet, named Kepler-47b is a complete resolution to 49 days, while the outer planet Kepler-47c, needs 303 days. Outer orbit is located in the so-called “habitable zone” around a planet zone, where it is too cold or too hot for liquid water to exist on the planet in question.
Although nearby is a giant gaseous planet, where life is unlikely new discovery shows that such planets “circumbinare” habitable zones may exist. One system has been discovered circumbinar later, but this is the first example of more than one planet around a pair of stars.
It is believed that gravitational perturbations generate of binary stars can be “cast” planets in the system, or they can send to devastating collision.
“Kepler-47 shows the typical architecture of planetary orbits coplanar with multiple planets can form around two stars. Circumbinare I learned that planets may be like planets in our solar system, but with two suns,” says Joshua Carter of the Harvard-Smithsonian Center for Astrophysics.
“Kepler-45c does not seem to have proper living conditions, but two months is high and they can be very interesting world,” said Professor William Welsh, University of San Diego.
