NASA's Kepler mission has made the first detection of a pair of planets orbiting two stars. The two stars systems are fascinating aspects of the entire Universe.
A new study suggests an Earth-size Alien planet was orbiting two Suns in its sky, like a "Tatooine World" from the film "Star Wars". Now, researchers found that the two stars systems have been large and gaseous, which is 5000 light years away from Earth.
In a statement by NASA scientists, such a planet could quite hospitable if located at the right distance from its two stars. It would not necessarily even have dessert. When the researchers investigated the "habitable zone" for "Tatooine World" then they found two-sun like star hosts a planet covered in water.
However, for better understanding, such factors, the researcher from Princeton University and NASA created a model for a planet in the Kepler 35 system. The two stars Kepler 35 A and B hosts a planet called Kepler-35b. This planet is eight times larger than Earth with an orbit of 131.5 Earth days. Now researcher examined, how this planet as it orbited the host stars with periods between 341 and 380 days.
"Habitable zone" is actually the range of orbit around a star, where a terrestrial planet is most likely to have liquid water on its surface. But in this case, two stars are orbiting each other. For this reason, habitable zone depends upon the distance from the center of mass of both stars. However, the planet around two stars would not travel in a circle, its orbit would stumble through the gravitational interaction with the two stars.
Near the edge of Kepler 35's habitable zone, the surface temperature of the two-stars planet stays almost constant. The deficiency of water vapor would also make the climate quite variable. Researcher again said that the global surface temperature would sway by 2 degree Celsius, reported by Space. Scientists Siegfried Eggl uttered that they are experienced by the huge temperate variation from day to night, in dry climates like dessert on Earth.
Moreover, the new models suggest, a water-covered planet around two stars would have less cloud coverage. A clean sky would provide a spectacular view of their double Suns.
