### What is the maximum survivable gravity for humans for say 8 months

Your main problem here is that no-one really knows... that's why all of the questions and answers linked in the "related" section on the right aren't all that helpful. The experiments simply ...

### What is the maximum survivable gravity for humans for say 8 months

Human tolerence for high gravity was discussed in Habitable Planets for Man (1964) by Stephen H. Dole, on pages 11-13. https://www.rand.org/content/dam/rand/pubs/commercial_books/2007/RAND_CB179-1.pdf ...

### If an otherwise too massive planet rotates fast enough, would the equatorial region become habitable?

Centrifugal acceleration $a_c$ in terms of radius $r$, angular velocity $\omega$ $a_c = r \omega^2$ On Earth at the Equator, this works out to roughly $-0.003 g$ where $g$ is acceleration due to ...

### If an otherwise too massive planet rotates fast enough, would the equatorial region become habitable?

Yes. Although a fast rotating planet also generates a much more strong coriolis wind, and living on a planet where the wind speed is close to the sound speed, that might not be fun. This effect we are ...

### What is the gravity above which launching into space is hindered?

When the specific impulse becomes so low that for any amount of fuel the engine won't be able to produce enough thrust to accelerate it out of the atmosphere and to orbital velocity. If you have a ...

### How do Hill spheres work for binary planets?

Hill spheres define the area surrounding a celestial body in which it can exert gravitational dominance over the orbit of a satellite. In the case of binary planets, where two planets revolve around a ...
