Gravity(g) is a function of a planets mass(m) and how big it is or radius(r) squared
g=m/r2
The mass of Uranus is 14 times greater than Earth, but it's radius is 4 times greater than Earth.
So approximately 14/16 = 0.875
The gravity on Uranus is actually 0.886g whereas Earth is 0.99732.
It is not weaker than Earth's gravity, as for it has more mass.
Gravity does not have a size, smaller would be an incorrect term.
What else can I help you with?
What planets are bigger than earth but smaller than neptune?
No planet is smaller than Neptune, but larger than Earth in diameter, but Uranus is there in mass. Uranus, even though larger, is less massive than Neptune. Neptune is a giant planet, but not as large as we believe. It is just 3 or 4 times larger than Earth in diameter, but is 16 times massive. Even Uranus is just 13 times. Jupiter and Saturn are much much bigger than all these planets.
Why is planet earth the have the weakest gravity?
It doesn't. Mercury, Venus, Mars, and Pluto have less gravitational acceleration at their surface than Earth has. That leaves only Jupiter, Saturn, Uranus, and Neptune with stronger gravity.
Why does Uranus have more mass but less gravity than earth?
Earth is not the most dense planet.The density of Earth is only 5.515 g/cm3 , butthe density of planet Kepler-70b (in the Cygnus constellation) is 64 g/cm3 !See Sources and related links below.
Which planet would you expect has the lowest surface temperature Uranus Saturn or Neptune?
Neptune is expected to have the lowest surface temperature among Uranus, Saturn, and Neptune. This is due to Neptune's farther distance from the sun compared to Uranus and Saturn, resulting in less solar energy reaching its atmosphere.
Is there more or less gravity on Neptune then on earth?
Neptune has slightly more gravity than Earth. It is believed that the gravity is 17% greater than Earth's.
Does planet Uranus have more or less gravity than earth?
The "surface gravity" is less on Uranus.

Do you way less on Uranus?
there is less gravity so you weigh less
What is the main size of Uranus?
Uranus is the 3rd largest planet in diameter but in mass (8.683e25 Kg) it's less then Neptune

What four planets are known to have rings?
Saturn, Jupiter, Uranus, and Neptune are the four planets in our solar system known to have rings. Saturn's rings are the most extensive and well-known, while the rings of Jupiter, Uranus, and Neptune are less prominent and harder to see.
Uranus has a bigger or less speed than Jupiter?
Uranus has a lower orbital speed than Jupiter.
Why is Uranus colder than Neptune?
Because Uranus's internal heat is lower than Neptune's -- possibly because it doesn't have a moon as large as Triton providing friction from gravitational drag -- Uranus is actually colder than Neptune, despite being almost a billion miles closer to the sun.
Why does Neptune take less time than Earth to spin around once?
Neptune is bigger then earth
