Your Age on Other Planets
Every planet orbits the Sun at a different speed. Enter your birthdate to discover how old you'd be on Mercury, Mars, Jupiter, and beyond.

How It Works
Age Calculation
Your Earth age in days is divided by each planet's orbital period (how long it takes to complete one trip around the Sun). Mercury zooms around in 88 days, while Pluto takes 248 Earth years.
Weight on Other Planets
Weight depends on surface gravity. Jupiter's gravity is 2.34x Earth's, so you'd feel much heavier. On Pluto, gravity is just 6% of Earth's - you could jump over a house!
Sunrises
Each planet rotates at a different speed. Jupiter's day is under 10 hours (you'd see ~2.4 sunrises per Earth day), while Venus takes 117 Earth days for one sunrise.
