Gliese and star
Recently, the team of Stéphane Udry have discovered a new planet named Gliese 581 g, which is an extrasolar planet orbiting the red dwarf star Gliese 581.
Gliese 581 g appears to lie in the habitable zone of space surrounding the star, and therefore could possibly host life as we know it.
For example, during the next 10 million years the known star with the greatest possibility of perturbing the Oort cloud is Gliese 710.

Gliese and systems
Some systems, such as HD 10180 and Gliese 581 contain multiple unconfirmed planets pushing the total expected number of planets to be discovered in their systems higher.
Gliese and within
Gliese 581 is another well known red dwarf system which is speculated to have multiple planets within the habitable zone.
The distance of closest approach of Gliese 710 is difficult to compute precisely as it depends sensitively on its current position and velocity ; Bobylev estimates that it will pass within 0. 311 ± 0. 167 pc ( 1. 01 ± 0. 54 light years ) of the Sun.
