Most of the planets in our solar system have years that are longer than days. It starts to break down a little nearer the sun though, if the time take for a planet to spin (rotate on its axis) is quite long. The orbital perios of the planets will be shorter as you get closer to the sun.
Mercury takes 88 days to go around the sun, so its year is 88 solar days. It spins very slowly on its axis though, once every 58.6 days relative to background stars. A solar day (apparent day) on Mercury takes 176 days though, because of this slow spin relative to the time taken to orbit.
Venus takes 243 days to spin on its axis relative to the background stars, while it takes 224.7 days to orbit the sun. Although its spin on its axis is longer that its orbital period, an apparent day is 116.75 days, since it spins in the other direction to Earth and most other planets.
What else can I help you with?
Do any planets have longer days or years?
No two planets in our solar system have the same length of day or length of year. Compared with Earth, these planets have longer years: Mars, Jupiter, Saturn, Uranus, Neptune. These have much longer days than Earth: Mercury and Venus. Mars has a day that's slightly longer than Earth's day. Depending on the particular definition of "day" that is used, two planets have a day that's longer than than that planet's year. They are Mercury (solar day) and Venus (sidereal day).
Why does it takes some planets only days to revolve around the sun and other planets more than one hundred years?
It takes longer because the planets are differant distances away from the sun, the greater the difference the longer it take
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.
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)
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.
What is a year on the planets?
The revolution times (Years) of the planets, in Earth days, is:-Mercury is 88 daysVenus is 224.7 daysEarth is 365.24 daysMars is 686.961 daysJupiter is 4,331.572 days or 11.86 yearsSaturn is 10,832.327 days or 29.46 yearsUranus is 30,799.095 days or 84.323 yearsNeptune is 60,190 days or 164.79 years*Pluto is 248 days.*Pluto is no longer a planet but a dwarf planetSee related question for rotational times (Days)
Which planets have more than 1000 days in a year?
Neptune's year is about 164 Earth years long.
Why do planets have different numbers of days in their years?
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.
What planets years are longer than its days?
Venus and Mercury have longer years than days. Venus takes about 225 Earth days to complete one orbit around the Sun, while a day on Venus (one rotation on its axis) takes about 243 Earth days. Mercury takes about 88 Earth days to complete one orbit but has a much slower rotation period, which means a year on Mercury is longer than a day.
Which planets year is one year longer than earths?
Mars, with a orbital period of around 687 days, almost two Earth years (which would be 730 days).
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.
Is 40 years longer than 15000 days?
No, there are 14,610 days in 40 years.
