The table below shows the time taken to make one revolution by the eight planets. Suppose your grandmother is 60 years old now, how many times has the planet Jupiter revolved around the Sun since the day she was born? Planet Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Time is taken to complete one revolution 88 Days 225 days 365 days 687 days 12 years 29years 84 years 165 years

The revolution of the earth and its tilted axis cause the seasons. Earth takes 365 days to complete one revolution around the Sun. One revolution of earth is equal to one year. 12 revolution of earth is equal to one revolution of Jupiter. Hence, 60 12 = 5 . Therefore, for 60 years on earth, Jupiter would have completed five revolutions around the sun.

The table below shows the time taken to make one revolution by the eight planets. How many times would the Earth go around the Sun by the time Saturn goes around it once? Planet Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Time is taken to complete one revolution 88 Days 225 days 365 days 687 days 12 years 29years 84 years 165 years

The movement of the Earth around the Sun in a fixed path is called a revolution. The revolution of the earth and its tilted axis cause the seasons. One revolution of earth is equal to one year. 29 revolution of earth is equal to one revolution of Saturn. Hence, 29 revolutions of the earth would be completed with one revolution of Saturn.

The table below shows the time taken to make one revolution by the eight planets. How many more days does Mars take to revolve around the Sun than the Earth? Planet Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Time is taken to complete one revolution 88 Days 225 days 365 days 687 days 12 years 29years 84 years 165 years

The revolution of the earth and its tilted axis cause the seasons. Earth takes 365 days to complete one revolution around the Sun and Mars takes 687 days to complete one revolution around the Sun. Therefore, to check the number of days more is given by, 687-365 = 322 days. Hence, it takes 322 days more for Mars to complete Mars revolution.
