Come on, introduce the order of planets that rotate the fastest to your little one!
Our Solar System consists of eight planets that revolve around the sun.
Planetary rotation is the rotating movement of a planet around its axis.
The rotation speed of a planet can vary.
For this reason, let’s find out the order of the planets in the solar system that rotate the fastest to the slowest.

The order of the planets that rotate the fastest

According to the National Oceanic and Atmospheric Administration, the following is the order of the planets that rotate fastest to longest.
Don’t get confused, OK!
1. Jupiter (9,9 jam)
Jupiter is the number one planet that rotates the fastest.
Jupiter can make one complete rotation in about 9.9 hours on Earth.
Due to its high rotation speed, Jupiter has the appearance of very active cloud belts and storms.
Launch in Cool CosmosJupiter has the shortest day among all the planets in the solar system.
Because Jupiter is a gas planet, it does not rotate as a solid ball.
Jupiter’s equator rotates slightly faster than its polar regions at 28,273 miles/hour (about 43,000 kilometers/hour).
2. Saturn (10.7 hours)

Saturn is a planet with famous rings.
As the order of planets that rotates the second fastest, Saturn’s rotation is around 10.7 hours on Earth.
Although Saturn is a larger planet than Jupiter in volume, its rotation is slightly slower.
Saturn is best known for its spectacular ring system.
These rings consist of ice, rock and dust particles that orbit the planet.
This ring stretches thousands of kilometers from the surface of Saturn but is very thin, about 10 meters.
Saturn has more than 80 known satellites. The largest and most famous is Titan, which is also the second largest satellite in the Solar System after Ganymede (a satellite of Jupiter).

3. Neptune (16.1 hours)
Neptune is ranked third in the list of planets that rotate the fastest. This with one full rotation takes about 16.1 hours on Earth.
The planet orbits the Sun in about 165 years, so one Neptunian year is equivalent to 165 Earth years.
Neptune is the farthest planet from the Sun in the Solar System.
Neptune’s atmosphere consists of a layer of gases consisting mainly of hydrogen, helium, and methane.
The planet has a distinctive bluish blue color caused by methane absorbing red light and reflecting blue light.
Neptune has strong winds and huge storms, including the Great Dark Storm which is similar to Jupiter’s Red Storm.
4. Uranus (17.2 jam)

Next, there is Uranus as the planet with the fourth fastest rotation.
Uranus has a rotation that is somewhat difficult to measure due to its extreme tilt.
However, if we measure from pole to pole, Uranus can make one complete rotation in about 17.2 Earth hours.
Uranus is the seventh planet from the Sun if calculated by distance.
The name Uranus is taken from the ancient Greek god, father of Saturn (Kronos) and grandfather of Jupiter.
This planet was first identified as a planet by British astronomer Sir William Herschel in 1781.
5. Earth (24 hours)
Earth, the planet we live on, has a rotation that takes about 24 hours to complete one complete rotation.
This time forms the concept of day and night on Earth.
Earth’s rotation is the rotating movement of the planet Earth around its own axis.
The Earth rotates along an imaginary axis connecting the North Pole and the South Pole.
This rotation is one of the two main movements of the Earth, the other being its revolution around the Sun.
The Earth’s rotation divides the day into day and night periods.

6. Mars (24,6 jam)

The order of the planet that rotates the sixth fastest is Mars.
Mars has a rotation that is almost similar to Earth, taking about 24.6 hours to make one complete rotation.
This makes a day on Mars quite similar to a day on Earth.
Mars has a diameter of about 6,779 kilometers, about half the diameter of Earth.
The planet is composed primarily of rock and metal, with a relatively large iron core.
The surface has mountains, valleys, and plateaus.
7. Mercury (58 days)
Mercury is the smallest planet in the Solar System and the seventh fastest rotating planet.
Mercury takes about 58.6 Earth days to make one complete rotation.
Additionally, Mercury has a 3:2 rotation relative to its revolution, which is unique among the planets.
Mercury has a uniquely slow rotation.
One side of Mercury always faces the Sun, so it experiences very high temperatures, while the other side is very cold.
This rotation affects extreme differences in temperature on the surface.
8. Venus (243 days)

Venus’ rotation is very slow, with one full rotation taking about 243 Earth days.
Because of this long rotation period, Venus has longer days than its years.
Apart from that, Venus also has retrograde rotation, rotating counterclockwise when viewed from above the North Pole.
This means that Venus rotates in the same direction as its orbit around the Sun.
Venus is one of the planets that is easily visible from Earth and is often referred to as the “bright star” visible in the sky at dusk or early morning.
In its journey around the Sun, Venus experiences phases like the Moon, which can be observed with a telescope.

Why is Pluto not included in the planets of the Solar System?
Pluto is no longer considered a planet in the solar system due to a change in the official definition of what distinguishes an object as a planet.
In 2006, the International Astronomical Union (IAU) formulated an official definition for a planet that caused Pluto to lose its status as a planet.
According to the IAU definition, an object in the solar system must meet three criteria to be considered a planet:
The celestial body must orbit the Sun. The celestial body must have a shape that is close to round due to gravitational forces. The celestial body must “empty” its orbit, meaning it has no other objects near its orbit.
Pluto fails to meet the third criterion so it is not included in the list of planets that rotate the fastest.
There are other objects near Pluto’s orbit, namely objects in the Kuiper Belt which have similar characteristics to Pluto.
