First we would have to get there.

Although close by stellar standards, at 20.5 light years away Gliese 581 (or Gliese 581d as the planet is currently known)
is well beyond the reach of our technology.

What little is known right now is that the planet is about 1.5 times the diameter of Earth and about 5 times heavier.

It has a surface temperature that averages between 32F and 104F Earth averages about 58F.

This means that liquid water almost certainly exists there, but we have yet to determine its exact atmospheric composition.

Further observations may determine if oxygen exists, which would be the prime determinant if life exists there.

Well, living on a star could be difficult if you don't want to be used as fissionable material.
I assume you mean the planet which has recently been discovered with water a little over a lightyear out? It's a gas planet... and really hot... people couldn't live there (even though H2O exists).
