TRIBUNNEWS.COM, WASHINGTON - NASA space mission "Kepler" managed to find 11 new solar systems containing planets 26, said the United States Space Agency said in a statement Thursday.The findings were nearly double the number of planets that have been confirmed and three times the number of stars surrounded by a single planet. Such a system will help astronomers to understand how planets form an order.Planets that orbit close to the star at the center of their solar system and its size is estimated that one-half times the size of Earth and some even exceed the size of Jupiter. Estimated fifteen planets like Earth or Neptune-sized.Further observations are needed to determine whether the planet's solid surface like Earth or a thick blanket of Neptune's atmosphere. The planets are rotating around the sun in about six to 143 days. Everything is closer than the distance of Venus to the Sun."Based on the Kepler mission, we know about the chances of 500 ekso-planet in the galaxy," said Kepler program scientist, Doug Hudgins, at NASA Headquarters, Washington."When two years you looked at the stars in the sky no bigger than your fist, Kepler had discovered more than 60 planets and more than 2,300 candidates for the other planets," said Hudgins."It proves that our galaxy contains many less and orbit the planet," he said. Kepler, which launched in March 2009, is designed to find Earth-sized planets rotating around another star. Spacecraft that use large sized digital camera, called Photometer, to monitor the level of light emitted more than 1,500 stars that are in the field of view as the plane around the sun.Kepler's solar system scan range by searching for "stopping point", which reached the planet as it passes through a star, planet, causing it to dim. Rate overcast condition it becomes a benchmark for measuring the sun planet is compared with that.
