No. Despite being more massive than Earth, the low density resulting large diameter of Uranus result in gravity at the nominal "surface" being slightly weaker than the gravity on Earth. That being said, the "surface" does not actually exist; it is merely the level at which atmospheric pressure is roughly equal to sea level pressure on Earth. A person placed there would fall through the gaseous outer layers of the planet and would be crushed by the extreme atmospheric pressure deep within.
yes
Mars does not have extreme gravity! It is less than 40% of the earth's gravity.
No. The 'surface' gravity of neptune is only 1.14g, due to the low density of the planet. Surface pressure may 'squash' a person there though, although they would be frozen from the near 0K temprature. (approx -218C)
A person would freeze to death, and they would suffocate.
No. Surface gravity on Venus is slightly less than gravity on Earth. A person would, however, be crushed by the atmospheric pressure and cooked by the extreme heat.
Mercury does not have extreme gravity. Its gravity is only 38% of Earth's. If you are talking about Jupiter, then yes.
They would be dead because of extreme cold and lack of oxygen and crushed from the gravity.
Not at all! Since Uranus is gaseous rather than solid, its force of gravity is actually less than Earth's. If you weighed 100 pounds on Earth, you would weigh 86 pounds on the surface of Uranus, if you could find some place to stand on. You would freeze to death on Uranus, though, as the temperature is around -300 degrees F.
No. The gravity on Mars is about 38% of what it is on Earth, so you would actually be much lighter there. The only planet with gravity strong enough that it would render people unable to stand is Jupiter/
if we were to be on uranus the gravity would be 89% of what we get on earth.
yes
On Uranus, you would choke, be squashed, and burn up.
