How Weight Varies Across the Solar System
Weight depends on surface gravity, determined by mass and radius. Jupiter has 2.36x Earth gravity; Mars has only 0.38x.
Mass stays constant everywhere, but weight changes with gravity. On the Moon (1/6 g), you could jump six times higher.
The Sun has 27.9x Earth gravity. Pluto has only 0.063x, making a 70 kg person feel like 4.4 kg.
Frequently Asked Questions
Why different weights?
Weight = mass x gravity. Each body has different surface gravity based on mass and radius.
Mass vs weight?
Mass is amount of matter (constant, kg). Weight is gravitational force (changes with location).
Live on Mars gravity?
0.38g. Effects unknown long-term but likely bone/muscle loss. Exercise countermeasures needed.
Most similar gravity to Earth?
Venus at 0.907g. Saturn (1.064g) and Uranus (0.889g) are also close.
