Venus. The rotational (day) period is243.2 earth days, and the sidereal (year) period is 224.7 earth days, the only planet in our solar system that has a year that is shorter than a day.

Which two planets have the closest length of day?
Earth and Mars. Earth's day is 24 hours, while Mars' day is 24 hours 37 minutes.
What planets length of the day is 9 hours?
Mercury.
What two planets have similar length of day?
Earth has a 24 hour day and Mars has a 25 hour day.
What is the difference of The rotational period of the inner and outer planets?
Rotational time of the planets is random (the length of the planet's day), but the outer planets do spin faster than the inner planets.
Do all planets have a day that is 24 hours long and a year that is 365 days?
No, only earth. The planets year, or time it takes to make one orbit of the sun varies, depending on its distance from the sun. Mercury is the closest and will take around 88 days to go once around the sun, while Neptune (the furthest) will take around 165 years. Each of the planets spins are different. The time taken for one rotation is the length of a day - this is not really effected by how far it is from the sun, just how much speed it has from the formation of the universe. Some planets spin very slowly (even the other way in the case of Venus and Uranus). Some Planets spin very quickly.
Which two planets have the closest length of day?
Earth and Mars. Earth's day is 24 hours, while Mars' day is 24 hours 37 minutes.
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 there any planets with the same length of a day as earth?
The closest planet to Earth in terms of rotation period is Mars with a period of 24 hours 37 minutes 23 seconds. The second closest is Neptune at 16 hours.
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.
What planets length of the day is 9 hours?
Mercury.
Which two planets have the same length of day which is shorter than an earth day?
The two planets that have the same length of and Earth day but shorter than a Earth day are Neptune and Uranus because a Earth day on Neptune is 18 hours and 30 minuets Earth time, And Uranus is 17.24 hours. Thus Neptune and Uranus is closest to an Earth day being below 23 hours and 56 min (24 hours rounding).
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.
What would you define the length of a planets day?
by the rotation of the planet
What is the suns length of day?
I think that the sun doesn't have any length of day, because of the heat and how the planets revolve around the sun.
What is the antonym of year?
There is no antonym of year. Year is a noun. The closest you could maybe get is day? But year has no antonym. You could use something like length as the word and the antonym would be height. An antonym is the opposite of something.
What two planets have similar length of day?
Earth has a 24 hour day and Mars has a 25 hour day.
What is the planets length on the day?
23 Hours 57 Minutes and 14 Seconds
