Well, basically different planets take longer to orbit the Sun. For example, Jupiter takes longer to orbit than earth, so Jupiter has a longer year. On Venus, a day lasts longer than a year as it takes longer to spin on its axis that to orbit the sun.

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.


The planets revolve around the sun once during each what?

The planets revolve around the sun each year. The year for each planet is different because it either takes the planet longer or shorter to get around the sun than other planets. The year of each panet is mesured by how many Earth days or years it takes to get around the sun.Length of Planetary Year in Earth Days/Years:Mercury: 88 daysVenus: 225 daysEarth: 365.25 daysMars: 687 days or 1.88 yearsJupiter: 4,331.5 days or 11.86 yearsSaturn: 10,832 days or 29.46 yearsUranus: 30,799 days or 84 yearsNeptune: 60,190 days or 165 yearsPluto (dwarf planet): 90,410.5 days or 247.7 years


What is the period of orbit for all the planets in Earth days?

There is a table which lists all of the orbital periods of our solar system, and it is posted at Nine Planets. A link can be found below. The Nine Planets web site is one of the oldest and most complete astronomic web sites available. A link to their home page can also be found below.

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.

Why does it take so long for all eight planets to orbit around the sun?

It depends on the planet and how fast it's going. Also, planets further from the sun have a longer path to travel. for example: Mercury only takes 88 days because it has a shorter path than all the other planets. Earth takes 1 year.Here are all the orbital periods of the planets measured in Earth days and Earth years:Mercury: 87.97 days (0.2 years)Venus : 224.70 days (0.6 years)Earth: 365.26 days (1 year)Mars: 686.98 days (1.9 years)Jupiter: 4,332.82 days (11.9 years)Saturn: 10,755.70 days (29.5 years)Uranus: 30,687.15 days (84 years)Neptune: 60,190.03 days (164.8 years)


How frequently do the planets revolve around the sun?

What is the revolution period of all planets?

Mercury: 88 days Venus: 224.7 days Earth: 365.26 days Mars: 687 days Jupiter: 11.86 years Saturn: 29.46 years Uranus: 84.01 years Neptune: 168.4 years


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.


Which planet has 264 days?

No planet (in our solar system) has a year of 264 earth days. The two planets near to the sun than us have short years, all others have longer years.

Where do planets travel?

Planets travel round the Sun, but all orbit in different speed and length.For example;Earth: Orbit round the Sun=364 1/4 daysNeptune: Orbit round the Sun= 164 years 288 daysSaturn: Orbit round the Sun= 29 years 167 days
