The second day of July, 1776, will be the most memorable epoch in the history of America. I am apt to believe that it will be celebrated by succeeding generations as the great anniversary festival.
This means that if you are 15 years old on Earth you would be 62 years old in Mercury years. 2. Venus: It takes 224.7 earth days for Venus to travel once around the sun. If you are 15 years old on Earth, this would make you 24 years old in Venus years. 3. Earth: One year on planet Earth, or one orbit around the sun, takes 365.26 days. 4. Mars: Planet Mars goes around the sun once every 686.98 earth days. Hence, a 15 years old from Earth would actually be almost 8 years old in Mars years. 5. Jupiter: The planet Jupiter travels around the sun one time every 4,332.82 earth days. This would make a 15 year old from earth be barely over 1 year old in Jupiter years. 6. Saturn: Saturn goes around the sun once every 10,755.7 earth days. If you had lived 15 years on Earth, then you would be a little over half of one year old in Saturn years. 7.
planets of our Solar System. A year on Earth is 365 days â unless it is a leap year â but the actual definition of a year is the time it takes a planet to orbit the Sun. Mercury orbits the Sun in 88 Earth days, which is the shortest orbit of any of the planets.aturnâs year is 29.7 Earth years long. Our planet rotates 30 times in the time it takes Saturn to rotate once. A year on Uranus lasts 84.3 Earth years. One of the odd things about Uranus is that its axial tilt is so radical (97.8Â°) that it actually rotates on its side.
