I am afraid that according to the article about the planet European astronomers discovered recently "The new planet is about 50 percent bigger than Earth and about five times more massive. "
50 per cent bigger means it is a bigger sphere - more or less sphere.
5 times more massive means that gravity is larger, a pound or a kilo weigh five times more there.
Stephan Udri of the Geneva Univ. stated "we estimated that the temperature on the planet we discovered is between 0 and 40 degrees Celsius (32 to 104 degrees Fahrenheit) so this means it can sustain water in liquid form."
The statement means life can be in the water there or, if the planet is not covered with oceans, life may be on dry land. The Geneva Univ. computer model leaves both possibilities open for further investigation.
Other planets of some importance are being discovered, like the one the Washington Carnegie Institute commented about recently. (The first planet mentioned here is near Gliese 581, and is named Gliese 581 C, the second is near another star, Gliese 876.)
"Goldilocks" means the star's (the sun's) habitable zone.
