It's 8 times the mass of the earth (7.96), approximately, but the surface gravity is inversely proportional to the radius squared. Its radius is 2.24 that of earth. So the gravity on the surface is 7.96 divided by 5.0176, which is about 1.6. So it's only 1.6 times the gravity of the earth on the surface.

That gravity is livable....probably very uncomfortable, but it won't kill you. Now that doesn't mean the atmosphere or radiation levels won't kill you.
