Earth is not the most dense planet.
- The density of Earth is only 5.515 g/cm3 , but
- the density of planet Kepler-70b (in the Cygnus constellation) is 64 g/cm3 !

Uranus has more mass than Earth because it is a larger planet, but its lower gravity can be attributed to its lower average density. The lower density of Uranus means that despite its greater mass, the gravitational force it exerts on objects at its surface is weaker compared to Earth.

∙ 11y agoStrictly speaking, Uranus doesn't have "less gravity" than the Earth. It has less
"surface gravity".That's the strength of gravity at aplanet's surface.
Also, Uranus doesn't have anobvious"surface", so we have to be careful about where we measure the force of gravity.
The convention for gas giants (Jupiter, Saturn, Uranus, Neptune) is to consider the "surface" to be atthe depth of the atmosphere at which pressure is equal to Earth's atmospheric pressure at sea level.
The answer to your questiondepends on the factthat Uranus is less dense than Earth. While Uranus has 63 times Earth's volume, it only has 14 times Earth's mass.
The force of a planet'sgravity is related to the mass of theplanet and the inverse square of the distance from its center of mass.
For this reason (Uranus is not as dense as Earth), gravity isslightly weaker at the "surface" of Uranus than on Earth.

Wiki User
∙ 8y agoYes. Earth is the densest planet in the solar system.
Wiki User
∙ 9y agoNeptune has a smaller diameter than Uranus but it is more massive. This is because Neptune has a larger density than Uranus.

Does Uranus is wearker or stonger gravity then earth?
Uranus has weaker gravity than Earth. The gravity on Uranus is only about 89% of the gravity on Earth. This means that objects would weigh less on Uranus compared to Earth.
How much less would you weigh on Uranus than earth?
Weight is based on the gravitational force of the planet.On Uranus you would weigh only about 89% of the weight on earth.This despite Uranus having a mass which is 14% larger than earth, the gravity is is less because it is not a very dense planet.At 89%, you would feel a little lighter, but probably not enough to be noticed.
What is the mass of Uranus compared to earth?
The answer is Earth's surface gravity is a bit stronger than Uranus's.Uranus has an acceleration due to gravity of about 8.7m/s², whereas Earth has an acceleration due to gravity of about 9.8m/s².The approximate conversion for weight from Earth to Uranus would beEarth weight x 0.889.If you weighed 100lb on Earth you would weigh about 88.9lb on Uranus.Source: NASA's "Planetary Fact Sheet".Uranus has a mass somewhere around 8.7 * 10^26 kg, which is about 140 times the mass of Earth. However, its radius is also much larger than Earth's (about 8.1 times that of Earth). When you plug these numbers into the Universal Gravitation Law equation, you get an acceleration due to gravity of about 7.8 m/s^2. Earth's acceleration due to gravity is 9.81 m/s^2. Thus, Uranus's gravity is somewhat weaker than Earth's.Uranus' gravity compared to earth is 89% of what you would expreience on Earth.
What is the force of gravity in Uranus?
The force of gravity on Uranus is about 8.7 m/s^2, which is roughly 0.9 times the gravity on Earth. This means that objects on Uranus weigh slightly less compared to Earth due to its weaker gravitational pull.
What is the gravitational field strength on Uranus?
Uranus being extremely massive compared to Earth surprisingly has less gravity than Earth. The low density of Uranus makes Uranus have low gravity. If someone were to stand on Uranus, they would experience 89% of the gravity on Earth.

Why is there less gravity on moon?
The moon has less mass than Earth. Gravity is proportional to mass, so there is less gravity on the moon.
Does Neptune control Uranus' gravity?
No. The gravity of Uranus comes from Uranus's own mass.
Why is there less or no gravity on the moon then there is on earth?
There is gravity on the moon. It is about on sixth what it is on Earth. This is because the moon has less mass than Earth does.
How come earth has less gravity than other planets?
Earth's gravity is determined by its mass and size. Although Earth is not the largest planet in our solar system, it has a relatively high density compared to other planets, which contributes to its gravitational force being less than gas giants like Jupiter and Saturn. Additionally, Earth's distance from the Sun also affects its gravitational pull.
Why do you weigh on earth than on the earth?
There is less gravity on the moon to pull you towards its surface than here on earth. Your mass x gravity(acceleration) = your weight. There is less gravity because the moon has less mass than the earth. All objects with mass have some amount of gravity that pulls them toward other objects with mass. The more mass you have in one spot the greater the pull of gravity there.
Why is the gravity on the moon less than the gravity on earth?
Because the overall mass of the moon is less than the earths mass. The gravity of a body relates to the mass of that body.
Why does the moon have more gravity than the earth?
It doesn't. The moon has less gravity than Earth because it has less mass.
