According to one of the sources (either in the related threads or another new source—have looked at a fair amount so far), the planet would be subjected to tidal forces from its primary (its star). Earth also is subjected to tidal forces from the Sun, but the tidal forces from the Moon have more effect as the Moon is closer to Earth than the Sun. In contrast, Gliese 581 c is much closer to its sun than Earth is to the Sun.

or another news source.....

And the question about determining the gravitational force of a planet from its mass and a radius is an actual question--either in relation to Earth's gravitational force, or in terms of actual units independent of Earth.

That close to its primary it's going to be gravitationaly locked and not turning with respest to the primary. The force will be there but it'll be constant and won't affect anything

They are saying that the sun would be about 20 times wider than a full moon when viewed from the surface of the planet.
