Age on Other Planets Calculator
Calculate Your Age Across the Solar System
Discover how old you would be on Mercury, Venus, Mars, Jupiter, Saturn, Uranus, and Neptune!
Your Birth Date
How it works:
Your age on other planets depends on how long it takes each planet to orbit the Sun. A "year" on Jupiter is 12 Earth years!
How Does It Work?
A "year" is the time it takes a planet to complete one orbit around the Sun. Each planet has a different orbital period.
Example:
If you're 30 Earth years old, you're only about 2.5 years old on Jupiter because Jupiter takes 12 Earth years to orbit the Sun!
