# Does Mercury have the weakest gravity?

## Does Mercury have the weakest gravity?

Gravity on Mercury: This makes Mercury the smallest and least massive planet in the Solar System. However, thanks to its high density – a robust 5.427 g/cm3, which is just slightly lower than Earth’s 5.514 g/cm3 – Mercury has a surface gravity of 3.7 m/s², which is the equivalent of 0.38 g.

### How much gravity is there on Mercury compared to Earth?

Planetary Fact Sheet – Ratio to Earth Values

MERCURY EARTH
Mass 0.0553 1
Diameter 0.383 1
Density 0.984 1
Gravity 0.378 1

Why is the gravitational pull of Mercury and Mars lower than Earth?

That’s because the planets weigh different amounts, and therefore the force of gravity is different from planet to planet. 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.

#### Is the gravity on Mercury stronger than Earth?

Since Mercury has less mass than Earth, the surface gravity on Mercury is less than the surface gravity on Earth. The surface gravity on Mercury is only about 38% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mercury.

What gravity does Mercury have?

## Why is Mercury important to Earth?

Mercury’s magnetic field is strong enough to deflect the solar wind around the planet, thus creating a magnetosphere. The planet’s magnetosphere, though small enough to fit within Earth, is strong enough to trap solar wind plasma, which contributes to the space weathering of the planet’s surface.

How does Mercury compare to Earth?

Mercury has a diameter of 3,032 miles (4,879 km) making it a little more than one third the size of Earth. If Earth were the size of a baseball, Mercury would be about the size of a golf ball.

### What makes Mercury different from Earth?

While both are terrestrial in nature, Mercury is significantly smaller and less massive than Earth, though it has a similar density. Mercury’s composition is also much more metallic than that of Earth, and its 3:2 orbital resonance results in a single day being twice as long as a year.

Is the gravity on Mars less than Earth?

Since Mars has less mass than Earth, the surface gravity on Mars is less than the surface gravity on Earth. The surface gravity on Mars is only about 38% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mars.

#### What is the gravity on Mercury?

How does Mercury compared to Earth?

## What is the difference between Earth’s gravity and Mercury’s?

Since Mercury has less mass than Earth, the surface gravity on Mercury is less than the surface gravity on Earth. The surface gravity on Mercury is only about 38% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mercury.

What is the gravity of mercury relative to Earth’s?

This also means that Mercury’s surface gravity is 3.7 m/s2, which is the equivalent of 38% of Earth’s gravity (0.38 g ). This means that if you weighed 100 kg (220 lbs) on Earth, you would weigh 38 kg (84 lbs) on Mercury.

### What is the mass of Mercury compared to Earth?

In fact, Mercury’s mass is approximately 3.3 x 10 23 kg (5.5% the mass of Earth) which means that its density – at 5.427 g/cm 3 – is the second highest of any planet in the Solar System, only slightly less than Earth’s (5.515 g/cm 3).

How big is Murcury compared with Earth?

Mercury has a mean radius of 2,439.7 km in comparison to Earth with a mean radius of 6,371.0 km meaning the size of the planet is equivalent to 38% the size of Earth .
