Neptune/Length of day
Which planet has a longer year?
Neptune
Given its distance from the Sun, Neptune has the longest orbital period of any planet in the Solar System. As such, a year on Neptune is the longest of any planet, lasting the equivalent of 164.8 years (or 60,182 Earth days).
How long is 1 day for Neptune?
Why does Neptune take 164 years to complete?
Neptune orbits our Sun at an average distance (semi-major axis) of 4,504.45 million km (2,798.656 million mi; 30.11 AU). With an average orbital speed of 5.43 km/s, it takes Neptune 164.8 Earth years (60,182 Earth days) to complete a single orbital period.
How long is 1 second in space?
The light-second is a unit of length useful in astronomy, telecommunications and relativistic physics. It is defined as the distance that light travels in free space in one second, and is equal to exactly 299,792,458 metres (983,571,056 ft).

How long is 1 year in space?
**One year in space would be 365 days /1 year on earth….. It takes 365 days for Earth to complete 1 revolution around the Sun…
How long does a year last on Neptune?
Since Neptune is so far away from the Sun, a year on Neptune lasts for 165 Earth years. Although a day on Neptune is shorter than a day on Earth. This gas planet spins, or rotates, once every sixteen hours.
How long is a year on Neptune compared to Earth?
As such, a year on Neptune is the longest of any planet, lasting the equivalent of 164.8 years (or 60,182 Earth days). But since Neptune also takes comparatively little time to rotate once on its axis (16 hours, 6 minutes and 36 seconds), a single year lasts a staggering 89,666 Neptunian days.
How many days does Neptune have in a year?
This means, in effect, that a year on Neptune lasts as long as about 165 years here on Earth. However, given its rotational period of 0.6713 Earth days (16 hours 6 minutes 36 seconds), a year on Neptune works out to 89,666 Neptunian solar days.
How long is one year on Venus compared to Earth year?
Venus takes 224.65 Earth days to complete one revolution around the Sun, which is also the length of a Venus year. Compared to the Earth’s year, a Venus year is about 0.615 times (61.5%) that of the Earth.
