Slowest moving planet in the solar system

Which planet has the slowest orbital speed?

Uranus is the second slowest planet with an orbital speed of 6.81 km/s. This equates to 15,233 miles per hour. 8. Neptune travels around the sun at a speed of 5.43 km/s or 12,146 miles per hour. Although this is a very high rate of speed, Neptune still has the slowest orbital velocity of any of the planets.

What is the slowest planet in the world?

Venus: 10 Fun Facts About the Hottest Planet! The slowest naked-eye planet is Saturn, which is nicely up just before dawn. Its very name is used to epitomize sluggishness, when we say that something or someone is saturnine. The Moon spins slowly too, at just 10 miles an hour.

Which planet rotates the fastest?

Venus spins at a speed of 6.5 kilometres per hour. After Venus, Mercury is the slowest rotating planet. A day on Mercury lasts 58 Earth days, translating to a speed of only 10.8 kilometres per hour. Jupiter and Saturn have the fastest rotations in the solar system. Image credit: NASA/ESA The outer solar system is the realm of the gas giants.

Do planets move with constant speed?

Basically, the planets do not move with constant speed along their orbits. Instead, their speed varies so that the line joining the centers of the Sun and the planet covers an equal area in equal amounts of time. The point of nearest approach of the planet to the Sun is called perihelion.

Which rocky planet spins the fastest?

Interestingly, the Earth actually spins the fastest among the rocky planets, completing one rotation every 24-hours. That translates to a rotational velocity of 1,574 kilometres per hour. Mars is the second fastest, and its rotational velocity and length of day are quite similar to Earth’s.

How fast does Jupiter spin?

Jupiter spins faster than all the other planets, rotating at a tremendous speed of 45,583 kilometres per hour. A day on Jupiter is only ten hours. After Jupiter, Saturn is the fastest spinning planet, completing one rotation every 10.5-hours, translating to a speed of 36,840 kilometres per hour.
