New Earth

A new planet was discovered roughly 20 lightyears away.  However this planet discovery is different from other recently discovered is that this planet may be perfect to sustain life.  Specifically human life.  The planet(Gilese 581g) is close enough to the sun so that water wouldn't evaporate but not far away so  water wouldn't completely freeze, just like earth.  It is up to speculation whether or not life may already be on the planet.  Its also upfor speculation whether water is even on the planet.  However it is comforting to know there are earthlike planets out there for the day we have to leave ours
