# What is the rotation rate of Mercury?

## What is the rotation rate of Mercury?

59 Earth days
Mercury rotates slowly. One rotation takes nearly 59 Earth days to complete. However due to an orbital-rotational resonance ratio of 3:2, a fictitious observer on Mercury would see that a solar day from noon to noon would take about 176 Earth days to complete.

How many hours does it take for Mercury to spin?

Option 1: A Paragraph We can write a paragraph about how long days last on other planets. On Mercury a day lasts 1,408 hours, and on Venus it lasts 5,832 hours. On Earth and Mars it’s very similar. Earth takes 24 hours to complete one spin, and Mars takes 25 hours.

### How fast does Mercury spin in mph?

107,082 miles per hour
Mercury: 47.87 km/s (107,082 miles per hour), or a period of about 87.97 days.

Does Mercury have a spin?

The planet Mercury rotates three times about its spin axis for every two orbits about the Sun1,2, in a 3/2 spin–orbit resonance.

## Does Mercury spin clockwise or counterclockwise?

All of these planets orbit the Sun in a counterclockwise direction, and Mercury, Earth, and Mars rotate counterclockwise around their axes. Venus rotates slowly in a clockwise manner around its axis.

Does Mercury change direction?

Mercury spins around the sun quite a bit faster than Earth. When its orbit takes it past our planet, it appears to change its direction of travel across the sky.

### What is the fastest spinning planet?

Jupiter
Jupiter is the fastest spinning planet in our Solar System rotating on average once in just under 10 hours. That is very fast especially considering how large Jupiter is. This means that Jupiter has the shortest days of all the planets in the Solar System.

Which planet is moving fastest?

Despite its proximity to the Sun, Mercury is not the hottest planet in our solar system – that title belongs to nearby Venus, thanks to its dense atmosphere. But Mercury is the fastest planet, zipping around the Sun every 88 Earth days.

## How much would a 100 pound person weigh on Mercury?

38 pounds
For example, if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mercury. That’s because Mercury weighs less than Earth, and therefore its gravity would pull less on your body.

How was the rotation rate of Mercury determined?

How was the rotation rate of Mercury determined? Scientists use radar to determine the rotation of Mercury. The reflected beams off of the radar showed Doppler broadening. Mercury has a rotation period of 59 to 88 Earth long days.

### What is the speed of the rotation of mercury?

Rotation of Mercury. This means that a single day on Mercury last about 0.646 times as long as a single year. The planet’s equatorial rotational speed is 10.892 km/h. These periods are given in solar days. In sidereal days Mercury rotates every 58.647 days and orbits twice during every three rotations.

How long does it take for Mercury to go around the Sun?

Mercury spins slowly compared to Earth, so one day lasts a long time. Mercury takes 59 Earth days to make one full rotation. But a year on Mercury goes fast. Because it’s the closest planet to the sun, it goes around the Sun in just 88 Earth days.

## How long is a year on Mercury compared to Earth?

Mercury likes to keep things simple. Mercury spins slowly compared to Earth, so one day lasts a long time. Mercury takes 59 Earth days to make one full rotation. But a year on Mercury goes fast. Because it’s the closest planet to the sun, it goes around the Sun in just 88 Earth days.

What is the fastest and slowest spinning planet?

Jupiter is the fastest spinning planet while Venus is the slowest. Venus takes 243 Earth days to complete one rotation on its axis, making it the slowest of all planets. At the equator, Venus is spinning at the speed of 4.05 miles per hour compared to the Earth which spins at its equator at a speed of 1,037.6 miles an hour.
