Mercury has the smallest mass of the 8 planets at 5.5% of the mass of the Earth. It therefore has the least gravity of all the planets.

How is the surface gravity of the terrestrial planets related to the type of atmosphere that they have?

The acceleration of gravity at the surface of each terrestrial planet is proportional to the mass of each planet and inversely proportional to the square of the planet's radius, with Newton's gravitational proportionality constant, and is not correlated in any way with any characteristic of the planet's atmosphere. In other words: It ain't related.


Which planet has the highest surface gravity of the terrestial planets?

Earth


Why do the gases in the earth atmosphere stay close to the surface of the planet?

Gases in the Earth's atmosphere stay close to the surface due to the force of gravity acting on them. Gravity pulls the gases towards the center of the planet, keeping them from escaping into space. The mass of the Earth is sufficient to maintain an atmosphere that surrounds the planet.


How are the planets sizes related to their surface gravity?

Planet sizes are directly related to their surface gravity due to their mass and radius. Larger planets typically have greater mass, which increases their gravitational pull. However, if a planet is significantly larger but less dense, its surface gravity may not be as high as expected. Thus, surface gravity is influenced by both the planet's size (radius) and its density (mass per unit volume).


How does a planet's gravity vary with its mass?

The gravity of a planet is directly proportional to its mass, and inversely proportional to the square of the distance from the center of mass. For the gravity on the surface of the planet, the distance is just the planet's radius. Thus, if a planet has three times the mass, it has three times the gravity. If you are three times as far away, the gravity decreases by a factor of nine.

What classified planet has the least gravity?

Mercury, because it's the smallest if you don't consider Pluto to be a planet.


What is the force of gravity at the surface of the eight planets called?

The force of gravity at the surface of the eight planets is called surface gravity. It is the gravitational pull experienced by objects on the surface of a planet due to its mass.


Is there a relationship between the distance a planet is from the sun and its surface gravity?

Yes, there is a relationship between a planet's distance from the sun and its surface gravity. The closer a planet is to the sun, the stronger the gravitational pull from the sun, which can affect the planet's own gravity. However, other factors, such as a planet's mass and composition, also play a significant role in determining its surface gravity.


Which planets have the largest accelerations of gravity?

The planet that has the largest acceleration of gravity is Jupiter. The planet with the least amount of gravity is Mercury. Actually, Pluto has less gravity than Mercury, but Pluto is not classified as a planet any more.


What planet has the highest surface gravity of all the terrestrial planets?

Earth is the most massive terrestrial planet, so it has the highest surface gravity.


Is the pull of gravity from other planets the same as Earth?

No. The gravitational pull at the surface of a planet depends on that planet's mass and radius. Jupiter has the strongest gravity of any planet in the solar system: 2.53 times the surface gravity on Earth. Mercury has the weakest surface gravity at just 37% the gravity on Earth.

Mars has the lowest surface gravity (0.376g), just a little lower than that of Mercury (0.38g

How does gravity affect weight on a planet?

The importantidea here is a planet's "surface gravity". That's the measure of the planet's gravitational "pull"at its surface. The larger this number, the heavier the weight ofan object on the surface of the planet. For example, the "surface gravity" on Mars is only 38% of the Earth's. So, if you could be on the surface of Mars, your weight would be 38% of your weight on Earth.


On which planet will you weigh the least?

Mars has the lowest gravity of the planets in our solar system.Some people believe than you would weigh the least of Mercury because it is the smallest planet, but Mercury is more dense than Mars and thus has a stronger gravitation force.It's not much between them:Mars - 0.376gMercury 0.38 gEarth (For comparison) 0.99732 gSee related link for the other planets.Mars or Mercury. Both have a surface gravity of about 38% of Earth's.


How does a planet's size affect its gravity?

The distance between a planet and an object affects the gravitational force between them. That means the size of a planet affects the value of the "surface gravity" for that planet. The greater thedistance from the surface to the center of the planet, the smaller the gravity at the surface (for the same planet mass). An example is the fact that Mars and Mercury have almost exactly the same surface gravity. Mars has more mass than Mercury, but this is balancedby the fact that Mercury hasthe smaller radius.
