Analysis: The length of a year on different planets is different. In astronomy, we calculate one year according to the time of planets' revolution.
On Jupiter, the orbital period of Jupiter is 11.86 years. According to the lifespan of a human being at a hundred years of life, the "year" on Jupiter is about 8.43 years.
On Saturn, the orbital cycle of Saturn is 29.5 years. According to the calculation of Saturn's years, we humans can live to about 3.9 years.
On Uranus, the orbital cycle of Uranus is 84 years. Based on the years on this planet, we can still be one year old.
If we switch to Neptune, the orbital cycle of Neptune is 164.8 years, which is more than a hundred years old than humans. If we calculate on Neptune according to the years of Neptune, we will not even be one year old.
If you want to have a few more birthdays, it is actually better to go to Mercury, because the year on Mercury is equivalent to 88 days on Earth. If calculated based on Mercury years, we can live up to 414.7 years. Isn’t that great?
