On all but two planets, the years are longer than the days. (This is a transposition of the related question below.)
On Mercury, the (rotational) day is 59 Earth days long, but its short year of 88 Earth days produces "solar days" that are 176 Earth days, or twice as long as the year.
On Venus, a (rotational) day is 243 Earth days, but its year is only about 225 Earth days long. However, Venus spins on its axis in the opposite direction that the other planets do. The combination of slow clockwise spin and shorter year gives Venus an apparent "solar day" of about 117 Earth days. (While there is light at the surface, the Sun is never actually visible on Venus.)

∙ 11y agoVenus: Venus has a "sidereal" day (rotation period)that's longer than its "year" (orbital period).
A siderealday on Venus is equal to about243 Earth days, whereas a year is about 224.7 Earth days.
Mercury:
It takes Mercury about58.64 Earth days to spin on its axis - which is one Mercury siderealday. However, the "solar " day on Mercury is about 176 Earth days long.It takes Mercury about87.96 Earth days to orbit the Sun, which is defined as one Mercury year.
So, for Mercury it is thesolar day, not the sidereal day that is longer than its year.
(A solar day on Earth is 24 hours. A sidereal day, which is how long it takes Earth to spin on its axis, is about 4 minutes shorter.A year on Earth is about365.25 days - which is how long it takes Earth to orbit the Sun.)

∙ 14y agoPlanets with rotation periods longer than Earth's day : * Mercury : 1407.5 hours (Earth), or over 58 ½ Earth days. * Venus : 5832.4 hours (Earth), or over 243 Earth days (planet spins slowly clockwise, sunrise to sunrise is 116.75 Earth days) * Mars : 24.6 hours (Earth), slower rotation but smaller circumference Planets with rotation periods shorter than Earth's day : * Jupiter : 9.925 hours (Earth) * Saturn : 10.5 to 10.75 hours (Earth) - rotation speed varies by latitude * Uranus : 17.25 hours (Earth) - the actual "day" for any point is 84.3 years long. Because Uranus rotates on its side, day and night are provided by revolution, not rotation. If it were a solid planet, locations would have 42.15 years of constant daylight and 42.15 years of constant night, similar to the polar regions on Earth. * Neptune : 16.1 hours (Earth)

What planets days last longer than its years?
Pluto(i think)
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.
How long are years on other planets?
Mercury - 88 Earth days Venus 225 Earth days Mars 687 Earth days Jupiter 11.86 Earth years Saturn 29.46 Earth years Uranus 84 Earth years Neptune 164.8 Earth years (dwarf planet Pluto 247.7 Earth years
How long does it take for the main planets to orbit the sun?
Pluto--248 earth years Neptune--165 earth years Uranus--84 earth years Saturn--29 earth years Jupiter--12 earth years Mars--687 earth days Earth--365 earth days Venus--225 earth days Mercury--88 earth days
How long is a year on other planets?
A year on Mars is 688 days. A year on Pluto is 247 Earth years and a year on Jupiter is 11 Earth years. A year on Saturn is 29 Earth years and a year on Mercury is 87 Earth days.
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).
What planets years are longer than its days?
venus!
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.
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)
What planets days last longer than its years?
Pluto(i think)
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).
Can a planets day be longer than a planets year?
Yes - a prime example is the planet Venus... Its 'day' is 243 Earth days, and it's 'year' is 225 Earth days, meaning a day on Venus is longer than it's year !
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.
Do planets tend to have more earth days the further they are from the sun?
Yes, planets that are farther from the sun have larger orbits and it takes then longer to revolve around the sun. Therefore, they have more earth days.
What planet has its years longer than its days?
earth
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.
