# What is the relative surface gravity for the planets?

# Which planet has the lowest gravity at its surface?

Mars, bizarrely... The mean surface gravity of a planet is determined primarily by its mass and its radius. Prior to the reclassification of the major bodies in our solar system, the smallest planet by volume and mass was Pluto . Pluto has a mean surface gravity of 0.062 Earth equivalents. …However, Pluto has been reclassified as a dwarf planet. This demotes the planet Mercury into last place in terms of volume and mass. You might expect, therefore, Mercury to have the lowest surface gravity of the eight major planets. However, the planet Mars , despite having about twice the mass of Mercury, has a radius about 1000 km larger. So, actually Mars has a fractionally lower mean surface gravity. Mercury = 0.3772 Earth equivalents Mars = 0.3769 Earth equivalents (measured at the equator). For "surface gravity", the mass of a planet is effectively concentrated at the center (the center of mass). So, the gravitational force is less when the surface is further from the center of mass. So, a planet's surface gravity increases with its mass, but reduces with its radius. One of the small contributory factors to this reversal in expected ranking may be due to the comparatively slow rotation of Mercury (58.6 Earth days per rotation with an average speed of 10.9 km/h. Compare Mars: 1.03 Earth days and 868 km/h). The small rotational speed on Mercury means the outward acting centrifugal effect, which opposes the inward pull of gravity, is small. (Strictly speaking this only matters when we are talking about what scientists call "apparent surface gravity".) (MORE)

# What factors determine the surface gravity of a planet or a satellite?

The force of gravity as defined by newton is F= G*(M*m)/r 2 \n.
\nG is the gravitational constant. M and m are the masses of the two objects. r is the distance between the two objects. The thing that Newton could not explain was that the mass of an object used when determining gravity is the s…ame as the mass for an object used in his famous F=ma. This phenomenon was later explained by Einstein with his Theory of General Relativity. The mass, distance from the source (planet). The formula for gravity is force equals the gravitational constant (G) time the result of Mass one times Mass two divided by the distance between the two objects (r) squared. (MORE)

# If two planets have the same mass but different diameters Which planet has the stronger gravity at its surface?

The smaller diameter. Because the formula is G* m1 * m2 / r^2 . The gravity is negatively correlated with square of the distance between mass centers of the objects. When the distance increases the gravity decreases.

# Why is your weight regulated by earth's surface gravity instead of Jupiter's since Jupiter has such a great surface gravity and the planet is so big?

Yes, Jupiter has stronger gravity at its surface than does earth. However, to understand why we are affected by earth's gravity instead of Jupiter's you must go to Newton's laws. Jupiter's gravity decreases according to the distance. You will need to look at the formula. Then you can calculate a num…ber with a decimal place and a bunch of zeroes before you reach the first significant figure. You can then figure out how much Jupiter's gravity affects you over this distance. Go ahead. Find the formula. Get the answer. (MORE)

# Is there a relationship between the surface gravity and the density of a planet?

Absolutely. The two factors that affect gravity are density and volume. For example Jupiter has 11 times the diameter, and 1400 times the volume of Earth, and yet only experiences 2.5 times the gravitational pull of earth. The reason is the density of Jupiter is 1/4 that of Earth.

All mass produces a gravity field. All planets have mass. Therefore all planets have gravity.

# What planet has the greatest surface gravity and why?

Jupiter has the greatest acceleration due to gravity at surface radius @ 23.1 (m / s) / s, (Compared to that at earths surface of 9.82 (m / s) / s.) The effect of a planets gravity, is a combination of its mass, and your distance from its centre. The following equation gives the force of gravity (in… newtons) between two bodies. f = (G*m1*m2) / d 2 G = newtons gravitational constant m1 = planets mass m2 = objects mass d = distance between centres of gravity Note; say you removed yourself to 2 * surface radius of Jupiter, the force of gravity would be 1 / 4 that of the surface (MORE)

# What is the relative surface gravity for Eris?

That's hard to say. Not much information is available about Eris. It is known that it is a dwarf planet in the inner ring of the Kuiper Belt. But probes have no yet reached Eris, so we do not know what it is made of, thus what its mass is (approximately), thus what its relative gravity is.

# 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.

# What is the force of gravity at the surface of the planet of Neptune?

No one really knows because scientist can't sens aircraft because it is to far frome earth. But they have sent spacecraft.

But it depends on what you mean by the surface, because what… we see of Neptune is only the top of very thick dense clouds. (MORE)

# What is the surface gravity of the planet Ceres compared to earth?

The equatorial surface gravity on the Plutoid dwarf Haumea is estimated at 0.44 m / s 2 . That's 4.49% of Earth's. If you weigh 200 pounds on Earth and somehow scored a ride to Haumea, you'd weigh just about 9 pounds there.

# How does the sun's gravity and relative distance affect the orbits of planets?

The Sun's gravity force is the sole thing that keeps the planets in their orbits. Without it they would all fly off into outer space. The relative distance is important because the force is weaker at larger distances, so the planets there move more slowly. The theory was worked out by Isaac Newton …and others from the 18th century onwards, using earlier theory by Kepler in the 17th century. (MORE)

# What causes surface gravity on planets?

Gravity is a result of mass. All planets, even fairly small ones,have an enormous amount of mass and so have noticeable surfacegravity.

# 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 directlyproportional to the object's mass and inversely proportional to thesquare of the distance from the center of mass. So, if we double anobject's mass the gravity is double. If we triple the mass thegravity is tripled. By contrast if we double the …distance we end upwith one quarter the gravity. If we triple the distance we end upwith 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 theobject, and "r" is the distance tot he center of mass. In the case of the surface gravity of a planet, the distance to thecenter of mass is the planet's radius. So if two planets have thesame mass but are of different sizes, the larger planet willactually have weaker surface gravity. In most cases a larger planetwill have a greater mass than a smaller one, but not always asplanets vary in density. Event if the larger planet is moremassive, 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 ofEarth. From these figures we find that the gravity on Uranus is0.906 times or 90.6% of Earth's surface gravity. (MORE)
