Observations MW Keck observatory in Hawaii, United States, over 11 years to fruition.The scientists found a planet that is most similar to Earth. That possibility could be habitable planets humans.
As reported by Telegraph.co.uk, 29 September 2010, a team of “planet hunter” named the planet most similar to Earth’s with the name Gliese 581g.
Planet Earth in size nearly equal to the orbit and are in the middle ‘habitable zone astrology’. Researchers also found that the liquid can exist in the planet’s surface.
This will be the planet most like Earth that have never encountered before. This is also the first planet inhabited by human beings the most potential.
“Our findings are very interesting and offers the possibility that the planet is potentially habitable,” said Professor Steven Vogt at the University of California.
Earlier, the U.S. space agency (NASA) also find Earth-like planets, Kepler 9.
Gliese 581g was found on the basis of observations made using sophisticated techniques combined with a telescope ‘old’.
The most interesting of the two planets is Gliese 581g, he has three to four times the mass of the Earth and an orbital period of just under 37 days. The volume of the mass showed that the planet is probably rocky planet with a certain surface. It also shows that the planet has enough gravity.
Gliese 581g is located a distance of 20 light-years from Earth, precisely located in the constellation Libra. The position of this planet, one side always faces the star and have a hot temperature that allows people to sunbathe on an ongoing basis during the day. On the side facing away from the star, are in constant darkness.
The researchers estimated the average surface temperature of the planet is between -24 and 10 degrees Fahrenheit or -31 to -12 degrees Celsius. Temperature will be very hot when its position facing the star and freezing can occur when it is dark.
According to Professor Vogt, on the surface of the planet’s gravity is almost equal or slightly higher than the Earth, so that people can easily walk upright on this planet.
“In fact, we were able to detect the planet is so fast and so close. It has a sense that this planet is really characterized by a general, like the Earth,” he explained.
Prof. Vogt and Paul Butler of the Carnegie Institution in Washington, said the new team’s findings were reported in a paper to be published in the Astrophysical Journal.
