A solar system that consists of one star and the seven planets are detected is 127 light years from Earth. Predictably, the largest of this solar system in the universe, and beyond the sun.
As reported by Dailymail Wednesday, August 25, 2010, astronomers have studied this system for six years using the planet finder instrument called HARPS spectrograph at La Silla, Chile.
"This is a remarkable discovery. This, too, pointed to the fact that we are entering a new era in research Exoplanet (planets outside the system of governance turya): Study sestem complex on the planet," said Christophe Lovis scientist who led the European Southern Observatory (ESO).
He explained that studies the movement of this planetary system reveals the complexity of the gravitational interaction between planets. These findings, he said, gives scientists insight related to long-term evolution of planets of this system.
Astronomers has confirmed the existence of five planets in the solar system this newfound and was groping the other two because it is not affordable. Parent star distance of the solar system follows the general pattern of a solar system like the sun. Named parent star HD 10 180, located in the southern part of the collection Hydrus star, and is 127 light years.
Five planets in this solar system orbits from six to 600 days. Distance of planets from 10 180 HD ranged 0.06 to 1.4 times the Earth-sun distance. While mass ranged from 13 to 25 times the earth.
Dr. Lovis adding scientists have reason strong enough to declare that two other planets do exist. "One would like Saturn (with a minimum mass of 65 Earth masses) and orbits in 2200 days. One more, will be smaller, about 1.4 times Earth's mass," he explained.
This planet, he said, perhaps like the earth is filled with rocks. However, scientists doubt there is life on this planet, because it is too close to its parent star so very hot.
