Planets age

Planets age on this website means how old you would be on diffret planets in our Solar System. E.g. if planet Mercury takes 88 days to orbit around the sun, which is 4 times faster than our Earth, a one year old baby will be 4 on Mercury's years.

Planets that are futher away than us, need more time to orbit. E.g. planet Mars needs nearly 2 years to one rotation. It means that your age on Mars will be only half of your Earth age. Its great, as you are younger but your birthday happens every 2 years. Now you now real reason why Elon Musk is so desperate to fly to the Mars. He just want to be young :)

Rotation Period Orbital period
Mercury 58.6 days 87.97 days
Venus 243 days 224.7 days
Earth 0.99 days 365.26 days
Mars 1.03 days 1.88 years
Jupiter 0.41 days 11.86 years
Saturn 0.45 days 29.46 years
Uranus 0.72 days 84.01 years
Neptune 0.67 days 164.79 years
Pluto 6.39 days 248.59 years

There is not a reason to calculate age for some far away planets such as Uranus with an orbital age of 84 years, Neptune with 165 years, and Pluto the dwarf planet with 248 years.
