Planets travel at different speeds along their orbits around the Sun. Said orbits also become exponentially longer the farther away the planet is from the Sun. As a result, the time it takes for each planet in the Solar system to complete one trip around the Sun, or a year as we commonly say, varies greatly.
The calculator below will help you find out what your age would be on Mercury. Below, you will find a more detailed explanation of how this is calculated and the numbers that factor into it.

Note: the “months” estimated above are found by dividing the planet’s year by 12, like we do on Earth. There is no standard for how long a month would last on a different planet.
How to Calculate Your Age on Mercury
When we say that we are going to calculate your age on a different planet, what we mean is finding out the number of orbits that the planet has completed in the same amount of time as your age here on Earth.
Calculating your age on Mercury is very simple as we have to do a rule of three. The formula is as follows:
Mercury Age = (Earth Age in Years × Earth’s Orbital Period) ÷ Mercury’s Orbital Period
Differences between Earth and Mercury’s orbits
| Earth | Mercury | |
|---|---|---|
| Orbit Length (km) | 940 million | 57.91 million |
| Rotation Period (Earth days) | 1 (24 hours) | 58.6 |
| Orbital Period (Earth days) | 365.25 | 87.97 |
| Distance to the Sun (million km) | 149.6 | 57.91 |
