Planets closer to the sun than Earth orbit the sun in less than one year (Mercury and Venus), while planets further out from the sun than Earth take longer than a year (Mars, Jupiter, Saturn, Uranus and Neptune). The further out you go, the longer it takes to orbit the sun.

Which planets have years longer than one earth year?
All planets with a greater orbit than the Earth.MarsJupiterSaturnUranusNeptune
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 days last longer than its years?
Pluto(i think)
Why do planets have shorter days than earth?
The length of a planets "day" is another way of saying the amount of time it takes a planet to rotate once on it's axis. Each planet does this in it's own good time. There are some basic principles behind it, but overall, there is no "one answer" we can pinpoint as to why planets rotate at different speeds. They simply do.
How is the speed of a planet related to its distance from the sun?
The speed of a planet varies with the distance from the Sun according to Kepler's Third Law, so that the planets closer to the Sun have higher orbital velocities. Since the gravitational effect of the Sun decreases with distance from it, the planets farther from the Sun do not have to move as rapidly to remain in orbit. (In fact, the speed is what establishes the orbit, not the other way around.) So the outer planets, in addition to having much farther to travel in their orbits, are also moving more slowly. This combination means that outer planets take very much longer to orbit the Sun than do the inner planets such as Earth. By comparison, the length of time it takes (in Earth years) for each of the outer planets to make one complete revolution around the Sun: Jupiter - 11.9 Earth years Saturn - 29.5 Earth years Uranus - 84 Earth years Neptune - 165 Earth years
Would a year on the planets take longer or shorter then an earth year explain?
It depends on the planet. The planets orbiting closer to the sun than earth (Mercury and Venus) have shorter years, because they have smaller orbits, and travel faster. The planets further from the sun (Mars, Jupier, Saturn, Uranus, and Neptune) have longer years because they have larger orbits and travel slower.
Would a year on Neptune be longer or shorter than on earth?
In terms of Earth years, longer.
Would a year on neptune be longer or shorter than earth year?
In terms of Earth years, longer.

Are inner planets large or small?
The inner, or Terrestrial planets are very small in comparison to the outer, or Jovian planets. The smallest Jovian planet, Uranus, is 14.5 times larger than the largest Terrestrial planet, Earth.
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).
Are years getting shorter or longer why?
Yes sometimes it gets longer because the earth has a strange gravitational pull that pulls and pushes from the sun
Would a year on the planet Uranus be longer or shorter than a year on earth?
A year on Uranus, would be approx 84.07 Earth years.
What makes years?
A year is defined as the time it takes for a planet to orbit the sun. This amount of time varies from planet to planet.In our solar system Venus and Mercury have shorter years than the earth, (ie they orbit the sun in less time than the earth) all the other planets have longer years than us.A year on Mars is about twice as long as a year on earth, on Neptune the year is about 165 of our 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)
How long is a year?
A year is the amount of time it takes for the Earth to orbit around the Sun once. That takes 365.2429 days or 365 days 5 hours 49 minutes 47 seconds Similarly other planets have their own years as well. Those closer to the Sun have shorter years, those further from the Sun have longer years. Mercury's year is about 88 Earth days, Neptune's year is over 164 Earth years.
What causes earths years to be shorter than Jupiter's years?
Well, we are closer to the sun, closer then Jupiter, so it makes our revolution shorterbecause we have a shorter distance to travel, hence Jupiter having a longer year then Earth.
