The Sun is only one of the trillions of objects in the universe, and when we look at the fact that our star has eight planets, we say that it is possible to have eight times the planets in the universe about the stars, which is an astounding figure, and it can not be only one of those Planets have a life on it? In fact, since 2000, hundreds of additional solar planets orbiting distant stars have been discovered. Some of these planets have been found like Earth, such as the planet Gliese 581d, a planet believed to have liquid water on its surface and one of the mysteries of the universe.
Because of its massive mass of 7 to 14 times the Earth's planet, the planet is classified as the Super Earth. In late April 2009, there were new observations from the original Discovery Team that the planet includes a habitable zone where liquid water can thus exist in life Another theory says that 581 d may be only a large rock material, but it is thought to be an icy planet that approaches the star of death so there will be no benefit to humans.
