Mercury: 58.64 days

Venus: -243.02 days

Earth: 1 day

Mars: 1.03 days

Jupiter: 0.41 days

Saturn: 0.43 days

Uranus: -0.72 days

Neptune: 0.67 days

Negative means the planet spins in the direction opposite of Earth.

Earth has a rotational period of one day by definition.

Note that because the gas giants have no surface, different parts rotate and different speeds. The listed speed is the average.

Mercury, Days to orbit sun = 87.97 Years to orbit sun= 0.24

Venus, Days to orbit sun = 224.70 Years to orbit sun= 0.62

Earth, Days to orbit sun = 365.26 Years to orbit sun= 1.00

Mars, Days to orbit sun = 686.97 Years to orbit sun= 1.88

Jupiter, Days to orbit sun = 4331.57 Years to orbit sun= 11.86

Saturn, Days to orbit sun = 10759.22 Years to orbit sun= 29.46

Uranus, Days to orbit sun = 30799.10 Years to orbit sun= 84.32

Neptune, Days to orbit sun = 60190.00 Years to orbit sun= 164.79

Days on other planets depend on the speed of its revolution on its axis, this could take any amount of time, from a few seconds to many Earth years if the planet is massive. The length of a planets year, however, depends on its orbit around its parent star (Given that it has an orbit.) and as we know, one complete orbit is a year. Orbits can vary in range, some planets can be very close to its parent star like the planet Mercury. Others range from 1 AU (Earths distance from the sun) to over 1000+ AU which makes these distant planets years very long. Their orbits can take up to 3000+ Earth years.

Within the Solar Sytem:
  • Mercury - 175.94 Earth days
  • Venus - 116.75 Earth days
  • Earth - 24 hours
  • Mars - 29.53 Earth days
  • Jupiter - 9 hours 55 minutes 33 seconds
  • Saturn - 10 hours 32 minutes 36 seconds
  • Uranus - 17 hours 14 minutes 23 seconds
  • Neptune - 16 hours 6.6 minutes
  • Pluto (Dwarf Planet) - 6 days 9 hours 17 minutes

For all planets, a year is the time it takes for the planet to revolve around the Sun once. the further the planet from the Sun, the longer the year.

Which question should you ask to find out the length of a planets year?

How is the length of the year is determined?

A planets year is the time it take to make one orbit of its star.


What is the length of a year on Uranus given in earth years?

84 known moons and planets


What is the length of time it takes planetary objects to revolve around the sun?

Typically, this length of time is called a "year". Each planet's year is a different length than that of the other planets and increases as the planet is further from the Sun.


How many days are a year on the dwarf planets?

There is no constant year length for planets, dwarf type or otherwise. A planet's period (year length) depends entirely upon how long it take to orbit its star. Depending on the planet and its situation, that might take a matter of a few days, or a few years, or even centuries.


What is the lengthof a year for all planets?

The length of a year for a planet is the amount of time it takes for the planet to make a complete revolution around the sun. For the Earth, this is about 365 1/4 days. The length of time for other planets in our solar system to revolve around the sun is can be longer or shorter.


Why does the length of a day and year vary from planet to planet?

Some planets rotate faster or than others. Also the planets take different times to orbit the Sun.


Are years on other planets the same length?

No. Every planet has different length years. The farther a planet is from the sun, the longer year it has. Mercury's year is only 88 of our days. Earth's year is exactly 1 year long. Jupiter's year is about 12 of our years, and Pluto's year is 248 of them.


What do the length of the planets year and its distance from the sun have in common?

There is a relationship between the planets distance from the sun and the time taken for one orbit (planets year), described in Keplers third law. The square root of the time taken to orbit the sun is proportional to the cube of the average distance between the sun.


How many minutes are in an hour on Jupiter?

60. The length of the year and the length of the day on Jupiter will differ from that of Earth because a year is the length of time it takes to complete a circuit around the sun and a day is the length of time it takes to rotate on its axis. However, hours, minutes, and seconds are units of time that do not change on other planets.


How does the length of a year compare between inner and outter planets?

The outer planets take longer to go round because (i) they are further away and (ii) they move more slowly because the Sun's gravity is weaker out there.
