Found, the Planet with Two Solar



U.S. astronomers announced the discovery of the planet with two suns in the most recent scientific journal Science. The planet, named Kepler-16b is roughly the same size as the planet Saturn in our Solar System, and is located about 200 light years from Earth. The planet is located at a distance of about 105 million kilometers from the two parent star, and has an orbital period of 229 days.

The planet was discovered using the Kepler space telescope, which was approximately 155 000 stars monitored. "This discovery is very surprising. Once again, something that used to exist only in science-fiction story, now a reality," said Alan Boss of the Carnegie Institution for Science's Department of Terrestrial Magnetism, one of the astronomers who wrote the scientific articles.

The study found the Kepler-16b that is led by astronomer Laurance Doyle of the agency Search for Extraterrestrial Intelligence (SETI) Institute, based in California, USA.

Previously, astronomers from around the world have seen some of the planet that they believe to be orbiting two stars at once. However, they have never seen these planets pass directly in front of the sun, so the discovery was the first evidence of a planet with two suns.

"Kepler-16b is the first instance, and no doubt from a sirkumbinari planet, ie a planet orbiting two stars at once. Once again this proves that our Solar System is just one form of variation of the planetary system that can be realized by nature." Josh Carter said of the Harvard-Smithsonian Center for Astrophysics, who are also involved in the present invention.

If there are creatures that inhabit the planet, they can enjoy moments of twilight, and two of the setting sun, as experienced by Luke Skywalker in Star Wars. However, the possibility of human-like beings on this planet is very small, given the very low surface temperatures, which ranged between minus 73 to minus 101 degrees Celsius.

Low temperature is possible because despite having two suns, both the size of the parent star is much smaller than our sun and emits less energy. The mass of the star is only one-fifth of the mass of the Sun, and both stars have only 69 percent of the mass of the Sun.

Besides surrounded by Kepler planet-16b, the two stars orbiting each other with each other in a "dance space" with an orbital period of 41 days.
