Gliese 581g has a surface gravity estimated to be between 1.1 and 1.7 times Earth's gravity. At 1.1x, it's possibly livable for humans, making it more interest

Gliese 581g has a surface gravity estimated to be between 1.1 and 1.7 times Earth's gravity. At 1.1x, it's possibly livable for humans, making it more interesting; 1.7x is probably too rough without some new technology or adaptations.
