Planets with Weaker Gravity than Earth:
* Mars: About 38% of Earth's gravity. You'd feel significantly lighter on Mars!
* Mercury: About 38% of Earth's gravity. Similar to Mars, you'd experience a noticeable lightness.
* Venus: About 90% of Earth's gravity. While weaker, it's still relatively close to Earth's gravity.
* Moon: About 17% of Earth's gravity. This is why astronauts appear to bounce on the Moon.
Planets with Stronger Gravity than Earth:
* Jupiter: About 2.5 times stronger than Earth's gravity. You'd feel incredibly heavy on Jupiter!
* Saturn: About 1.1 times stronger than Earth's gravity. Slightly heavier than on Earth.
* Uranus: About 0.9 times stronger than Earth's gravity. Almost the same as Earth's gravity.
* Neptune: About 1.1 times stronger than Earth's gravity. Slightly heavier than on Earth.
Important Note: Gravity depends on a planet's mass and its radius (how big it is). The more massive a planet is, the stronger its gravity will be. The smaller the radius, the stronger the gravity will be. So even though Jupiter is much larger than Earth, its lower density means its gravity is stronger.
