How long is a day on other planets

(ORDO NEWS) — We are accustomed to a 24-hour day, but on other celestial bodies in the solar system, this time of revolution around its axis is very different.

The length of the day on the planet depends on the speed of its rotation, and the year depends on the distance from the Sun. This is how long a day and a year last on all the planets of our star system

On our planet Earth, a day lasts about 24 hours (23 hours and 56 minutes to be exact), and this is called a sidereal day (the time it takes for a planet to rotate completely on its axis).

Other planets of our system also revolve around their axis and the length of the day on them can vary quite significantly.

How long is a day on the planets of the solar system

Mercury

Mercury is the closest planet to the Sun, and it takes 58.6 Earth days to complete a rotation around its axis. Also, because it is very close to the Sun, a year on this planet lasts only 88 Earth days.

Venus

If you could live on Venus, your day would be almost 243 days (or 5832 hours). An interesting fact is that a year on this planet lasts 225 days, which means that a day on Venus is longer than a year. Another fun thing to know is that Venus rotates backwards from Earth, so the Sun rises in the west and sets in the east.

Mars

They say that Mars is the twin of our planet, and the duration of the day on it is similar – 24 hours 37 minutes. This planet is farther from the Sun than the Earth, so the year on it lasts 687 Earth days.

Jupiter

This gas giant has a different rotation speed in the equatorial region and the poles. The cloud belts at the equator make a full revolution in 9 hours 56 minutes, while at the poles the time for a complete revolution is 9 hours 50 minutes.

The accepted length of a day on Jupiter is set by the magnetic field and is 9 hours 55 minutes. In addition, one year on Jupiter is equal to 4333 days on Earth (approximately 12 Earth years).

Saturn

Saturn is another gaseous planet, which also has a different rotation speed in different parts. However, scientists were able to establish the official length of the day on this planet – it is 10 hours and 33 minutes. One year on Saturn lasts 10,759 days on Earth, which is about 29 years on our planet.

Uranus

Uranus makes a full rotation on its axis every 17 hours and 14 minutes. However, a year on it lasts 30,687 days, which is equal to 84 Earth years. Just like Venus, Uranus rotates around its axis in the opposite direction from the Earth.

Neptune

If humans could live on Neptune, their day would be approximately 16 hours long and their year would be 60,190 days long. This means that a year on this planet is 164.8 years on Earth.
