Despite being the smallest planet, Mercury's dense iron core gives it nearly the same surface gravity as Mars.

Venus is close to Earth's size and mass, so its gravity feels the most familiar of any other planet.

Apollo astronauts weighed about one-sixth as much on the Moon, letting them bound across the surface in their bulky suits.

Mars's lighter gravity is one reason NASA studies how the human body adapts to long-term partial gravity ahead of future crewed missions.

Jupiter has no solid surface to stand on, but at the cloud tops its gravity is the strongest of any planet in the solar system.

Saturn is the least dense planet in the solar system, so despite its huge size its surface gravity is barely stronger than Earth's.

Uranus rotates on its side, but its gravity at the cloud tops is only slightly weaker than Earth's.

Neptune is smaller than Uranus but denser, giving it the strongest gravity of any planet besides Jupiter.

Pluto's gravity is so weak that a determined jump could lift you several feet off the ground.

You obviously couldn't stand on the Sun, but its surface gravity is roughly 28 times Earth's — enough to crush an unprotected human body.
