Gliese 710, a star about half the size of our Sun, will rip through a portion of our solar system’s Oort Cloud of comets some 1.35 million years from now. In the process, it’s likely to ...

Astronomers have made a surprising discovery about Gliese 229B, a well-known brown dwarf first identified nearly 30 years ago. Once considered a single "failed star," scientists have now revealed ...

While scientists believe conditions suitable for life might exist on the so-called "super-Earth" in the Gliese 581 system, it's unlikely to be transferred to other planets within that solar system.

ESO . This diagram shows the system of planets around star Gliese 667C. A record-breaking three planets in this system are super-Earths inside the star's habitable zone, where liquid water could ...

Dynamical evolution of the Gliese 581 planetary system, by H. Beust, X. Bonfils, X. Delfosse, and S. Udry. To be published in Astronomy & Astrophysics, 2008. RELATED TOPICS ...

As far as we know, Gliese 710 isn't set to collide directly with Earth, but it wil be passing through the Oort Cloud, a shell of trillions of icy objects at the furthest reaches of our solar system.

Robin Wordsworth, who researched Gliese 581d with the Institut Pierre Simon Laplace in Paris, said: "The Gliese system is particularly exciting to us as it's very close to Earth, relatively speaking.

Gliese 581g This rocky world -- if it does indeed exist -- is just 20 light-years away from our solar system. It's likely two to three times as massive as Earth and zips around its parent star ...

The other three planets in the Gliese system have masses of 16, five and seven Earths. The one with a mass of seven Earths, called Gliese 581 d, ...

The boundaries are shown for several possible ages (5, 7, and 9 Gyr-old) of the Gliese 581 planetary system. Following the latest estimation, Gliese 581 would be 7 Gyr-old.

Gliese 581g. This rocky world — if it does indeed exist — is just 20 light-years away from our solar system. It's likely two to three times as massive as Earth and zips around its parent star ...
