Different planets have varying lengths of days primarily due to differences in their rotational speeds and axes. Each planet rotates on its axis at a unique rate, which determines how long it takes to complete one full rotation — this is what we define as a day. Additionally, factors like a planet's mass, composition, and distance from the Sun can also influence its rotation. Consequently, some planets have very short days, while others take much longer to rotate once.

Do all planets have days and years?

They all have days and years, but they are all of different lengths to days and years on Earth.


Why are days longer and shorter on different planets?

Rotation of planets depends on their history of being hit by other planetoids ... thus it is entirely random.


What time is taken by a planet to orbit the sun?

Different planets have different times to orbit the Sun. Mercury takes 88 days. Uranus takes 84 Earth years.


Do all planets in your solar system have the same days in one year?

No. Different planets have different speeds of rotation and different lengths of year. As a result, they experience a different number of days. Here are the number of days in each planet's year with earth days in parentheses Mercury: 0.5 days (88 Earth days) Venus: 1.92 (243 Earth days) Earth: 365.25 Mars: 668.6 (687 Earth days) Jupiter: 10,476 (4,333 Earth days) Saturn: 24,491 (10,759 Earth days) Uranus: 42,718 (30,799 Earth days) Neptune: 89,666 (60,190 Earth days)


How lond does it take for the planets to revolve around the sun?

Each planet has a different rotation speed around the sun. Erth takes 365 days,Mercury takes 88 days, so there is no spped for all the planets


Why do other planets have a different number of days compared to other planets?

If you mean in a year, then it's because it takes different times to circle the sun then planet earth (because they are more far away or closer).


Why are some planets days longer then a earth day?

They spin at a different rate on their axis than the Earth does on its axis.

How are Jupiter's days different from other planets' days?

The length of each planet's days are different because they rotate at different speeds. A day on Mercury is equal to 58.5 days on Earth. A day on Mars takes 24 hours and 39 minutes on Earth. A day on Venus is 243 Earth days and a day on Jupiter is equal to 9.9 Earth hours.


What are the lengths of days on planets?

it varies


Do planets have the same number of days?

No. All the planets rotate at different speeds. Typical days for each planet are shown below: 1) Mercury - 176 Earth days 2) Venus - 116 Earth days 3) Earth - 24 hours 4) Mars - 24 hours, 39 minutes, and 35.244 seconds 5) Jupiter - 6 days 6) Saturn - 10 hours and 39 minutes. Each of the planets has different orbital periods to go around the sun, such as: 1) Mercury - 88 Earth days 2) Venus - 224 Earth days 3) Earth - 1 year 4) Mars - 687 Earth days 5) Jupiter - 12 Earth Years 6) Saturn - 29.6 Earth Years.
