Why are the days on different planetary objects different lengths?
Other planets also experience these changes in day and night length because they too are tilted on their axes. Each planet’s axis is tilted at a different angle. Jupiter is tilted only 3 degrees, so its change in day and night length as it moves around the Sun is less extreme than that of Earth.
What are the day lengths on other planets?
Length of the day on other planets
- Mercury – about 59 days.
- Venus – 243 days.
- Earth – 1 day.
- Mars – about 1 day, 0.6 hours.
- Jupiter – 9 hours.
- Saturn – about 10 hours.
- Uranus – about 13 hours.
- Neptune – about 15 hours.
What determines the length of a day and year on different planets?
The two fundamental determining factors are the rotation of the planet (obviously) and the revolution of the planet around the central star.
How many days does each planet takes to orbit the Sun?
The revolution of the earth around the sun is how we define the year. A year is the time it takes the earth to make one revolution – a little over 365 days….The Days (And Years) Of Our Lives.
| Planet | Rotation Period | Revolution Period |
|---|---|---|
| Venus | 243 days | 224.7 days |
| Earth | 0.99 days | 365.26 days |
| Mars | 1.03 days | 1.88 years |

Is time different on different planets?
Heavy things like planets create a gravitational field that slows down time nearby. This means that a clock on a spaceship far away from any planet would move faster than a clock near Earth. This is different from time dilation explained by special relativity, which says that fast objects move more slowly through time.
Why do different planets take different times to orbit the Sun?
This is because of two reasons – planets that are closer to the Sun will take a shorter time to orbit it than those farther away, and the closer a planet orbits the Sun, the Sun’s gravity can pull on the planet, making the planet orbit faster.
How long is a sol?
24 hours, 39 minutes and 35 seconds
Mars is a planet with a very similar daily cycle to the Earth. Its ‘sidereal’ day is 24 hours, 37 minutes and 22 seconds, and its solar day 24 hours, 39 minutes and 35 seconds. A Martian day (referred to as “sol”) is therefore approximately 40 minutes longer than a day on Earth.
