Astronomers in the United States (U.S.) claim to have discovered a planet outside our solar system inhabited the Earth, but could be fit for occupancy of living things. The strategic position of planets similar to Earth.
The position of the planet is 120 trillion miles, or about 193.1 trillion miles from Earth. The question is, how could they know that planet?
Researchers from the University of California at Santa Cruz, Steven Vogt, and R. Paul Butler, an astronomer at the Carnegie Institution in Washington reveals that they both use sophisticated telescopes on the ground. However, they do not immediately find a planet that hope.
The scientists seem to observe the movement of a star which they called Gliese 581 - for more than eleven years. Stars that is the orbit of an Earth-like planet, which they later discovered.
It is the sixth planet found around a team of scientists that Gliese 581. According to Vogt, two other planets seem promising for occupancy. While others are too hot.
In contrast, the five planets they found instead was too cold. Precisely the sixth planet that they deem fit, so-called Goldilocks. This means that the planet was not too cold nor too hot because its position is not too close and not too far from the star.
At first, the planet would be named Gliese 581g, considering that the center of rotation of the star called Gliese 581a. However, Vogt does not agree with naming it. "It's not a name that is very interesting, especially it concerns a beautiful planet," said Vogt.
She prefers the planet according to his wife's name. "I call it the World Zarmina planet," said Vogt.
Gliese 581 is considered as "dwarf star," only a third of the sun. Therefore, according to Butler, Gliese 581 would not be directly visible from ordinary telescope from Earth despite being in the constellation Libra.
The astronomers' discovery published in the Astrophysical Journal and the media also published by the National Science Foundation, Wednesday, September 29, 2010.
