You are not from this planet.


Humans measure Earth's complete rotation on its axis as 24 hours, or one day. And when Earth completes one orbit around the sun, the measure is 365.26 days, or one year. But not all planets in the solar system solar system, the sun and the surrounding planets, natural satellites, dwarf planets, asteroids, meteoroids, and comets that are bound by its gravity. The sun is by far the most massive part of the solar system, containing almost 99.9% of the system's total mass.  rotate or orbit at the same rate. That means there would be a difference in how you determine your age if you were to move to Mars Mars, in Roman religion and mythology
Mars, in Roman religion and mythology, god of war. In early Roman times he was a god of agriculture, but in later religion (when he was identified with the Greek Ares) he was primarily associated with war.
! Use the steps and chart below to calculate your age--in Earth-years or days--on each planet in the solar system.

STEPS TO FINDING YOUR AGE ON DIFFERENT PLANETS

A. How many days old you were on your last birthday: (Your Age) x 365.26 =

B. Now many days it has been since your last birthday: (Today, in number of days starting January January: see month.  1)--(Your birthday, in number of days starting January 1) + 1 =

If the result is less than 0--that means you have yet to celebrate your birthday this year--add an extra 365

C. How many days old you are today: Add the results from Step A to Step B =

D. How old you are on (planet): (Result in Step C) / (Length of planet year in Earth (lays)

E. Now many days old you are on (planet): (Result in Step C x 23.934 / (Length of planet day in hours)
