Cosmic Scale – Weight in Space

Ever wondered how heavy you'd feel standing on Mars? Or how high you could jump on the Moon?

Cosmic Scale turns your weight into a journey through the solar system. Enter your weight, pick your explorer, and swipe through 17 worlds — from the scorching Sun to the frozen plains of Pluto.

🪐 17 Worlds to Explore
See your weight on many of the major bodies in our solar system: Sun, Mercury, Venus, Earth, Moon, Mars, Ceres, Jupiter, Io, Europa, Ganymede, Saturn, Titan, Uranus, Neptune and Pluto. Each world shows your weight scaled to its real surface gravity. Mars pulls you down to just 38% of your Earth weight. Jupiter would crush you with 2.5× the gravity. The Moon? You'd weigh only 17% of what you do at home.

⚖️ Real Gravity, Real Physics
Your mass never changes — only gravity does. Cosmic Scale uses real gravitational data to show exactly how heavy you'd feel on each body. Switch between kilograms and pounds anytime.

🦘 Jump Simulation
How high can you jump here vs. on Earth? Set your typical jump height and watch side-by-side animations showing the physics-accurate difference. On the Moon you'd soar over 5 metres. On Ceres? Practically escape the surface.

🚀 Choose Your Explorer
Pick from three space adventurers: Neil the classic astronaut, Laika the legendary space dog, or Zorg — a visitor from beyond the solar system.
