How are planets different?

There are many ways the planets are different. One way is that they all have different gravity levels, they are all different shapes and sizes. Lastly that they are different temperature, and different material.


Explain how a larger planet could have a smaller surface face gravity then a smaller planet or why it could not?

The strength of gravity from a given object is directly proportional to the object's mass and inversely proportional to the square of the distance from the center of mass. So, if we double an object's mass the gravity is double. If we triple the mass the gravity is tripled. By contrast if we double the distance we end up with one quarter the gravity. If we triple the distance we end up with only one ninth the gravity.The formula for the strength of gravity is: g=G*M/r^2"G" is the Newtonian gravitational constant, "M" is the mass of the object, and "r" is the distance tot he center of mass.In the case of the surface gravity of a planet, the distance to the center of mass is the planet's radius. So if two planets have the same mass but are of different sizes, the larger planet will actually have weaker surface gravity. In most cases a larger planet will have a greater mass than a smaller one, but not always as planets vary in density. Event if the larger planet is more massive, the larger size can still result in weaker gravity.A perfect example would be a comparison between Earth and Uranus. Uranus is about 4 times the radius and about 14.5 times the mass of Earth. From these figures we find that the gravity on Uranus is 0.906 times or 90.6% of Earth's surface gravity.

The average sizes of the outer planets are smallest than the average size of the Pluto so that they can called them the dwarf planets.

How are planets sizes related to their surface gravity?

Usually, large size= large mass. The more mass you have the greater the gravity, but it also depends on how much mass is in a certain amount of space. For example if a large amount of mass spread over a large area the gravity will be less than if all that mass was condensed into a single point.


Which has a more powerful gravity a small planet or a large planet?

It would depend on the mass of the planets. The surface gravity of a planet is directly proportional to its mass and inversely proportional to the square of its radius. If two planets have the same mass but different sizes, the smaller planet will have stronger gravity because the surface is closer to the center of mass. Conversely, if two planets are of the same size, the one with more mass will have stronger gravity. Since larger planets usually have more mass than smaller ones they usually have stronger gravity, though not always.

What is gravity LIKE onother planets?

On all the planets it is a force that acts towards the centre of the planet. The force is different on the planes because they all have different size and mass. On Mercury, Venus and Mars the force of gravity can be calculated on the surface because those planets' sizes and masses are known and Newton's law of gravity can be applied. On those three planet the gravity would be less than on Earth. On the four outer planets it's more difficult because the planet we see is only the top of the cloud cover. It is not known if these planets have a rocky core that one could 'stand' on at all, because the atmosphere quickly becomes denser as the altitude is reduced, and there may be no suitable interface between rock and a reasonably gassy gas where an instrument could stand.


How does gravity between the sun and planets control the path the planets make around the sun?

The sizes of the Sun and planets determine the strength of gravitational pull of the planets on each other and the Sun. The Sun's mass is so great that the planets can't escape from the Sun's pull and so as the planets are moving by the Sun pulls them back into orbit.
