Your Age by Planet

The speedster: a year is ~88 Earth days. Your Mercury age is much higher than Earth age.

Thick clouds, slow year (~225 days); your Venus age is higher, but closer to Earth than Mercury.

A year takes ~687 days, so your Mars age is smaller than your Earth age.

Gas giant with a long year (~11.86 Earth years) — your Jupiter age is a tiny fraction.

Rings + long orbit (~29.45 Earth years); only a few Saturn years under your belt.

Tilted and distant (~84 Earth years); many people never complete a full Uranus year.

The far blue world (~165 Earth years); a single Neptune year spans generations.
