It has a good temperature between like 20 degrees F to 120 degrees F.I was reading about it and I lost my link.

Sorry Tibs and Summoulton but you are both wrong. It is Gliese 581 c (in lower case) and it is the second planet discovered in the system not the third. As I explain below.
Some of the brightest stars have names but most have catalogue numbers and exoplanet names add an extension.
A star name followed by a lower case a is the star itself.
A star name followed by a lower case b is the first exoplanet found orbiting that star.
Gliese 581 b is a Neptune sized outer planet found in 2005, too cold to be habitable.
A star name followed by a lower case c is the second exoplanet found orbiting that star.
Gliese 581 c found 2 days ago is the second exoplanet found orbiting Gliese 581
A star name followed by an upper case A is a star not a planet, the brighter of a binary or trinary system of stars orbiting one another. Polaris A is a star. Polaris B is a dimmer star. Polaris A b would be a planet of Polaris A and Polaris B b would be a planet of Polaris B.
Gliese 581 C would be a star therefore. There is no such star however.

It is called 581 c after its parent star Gliese 581. And the more I learn about it the more I am convinced it doesn´t harbor life. It is just too absurd. It is likely a gas planet with no solid surface. It is in a synchronous orbit meaning one side is always pointing towards the sun and the other is always dark. We don´t know anything about its atmosphere if it even has one. It is 5 times as massive as earth. It might be a rock or it might be just another gas planet with mostly hydrogen and helium in its atmosphere.

Gliese 581 C
('C' meaning the 3rd planet discovered around Gliese 581 star -- not necessarily the 3rd planet in order from that sun).

Scientist said that there was life on planet Mars!and Mars does have the appropriate temperature!

It has a *really* exciting name: 581 c. If it gets more attention someone will probably eventually give it a "household" name, of course. Check out the Yahoo! News article at http://news.yahoo.com/s/ap/habitable_planet;_ylt=AlOf12cVQJN.1y1M94OtT6Os0NUE

581C and supporting the life on the planet is a red dwarf that acts like its sun

It doesn't have a name . It's referred to by a number within a galaxy.
