If Earth's gravity is 1 what is Uranus' gravity?
You are suggesting a dimensionless scale in order to compare gravities, but you are leaving the nature of the scale a little fuzzy. However, making a comparison of Earth's and Uranus' gravities, we find that the surface gravity of Earth (.997 g's) and Uranus (.886 g's) are very close. To the nearest unit of your scale, we could conclude that the gravity of Uranus is equal to 1. Uranus is much more massive than Earth; about 14.5 times as massive. But Uranus is much less dense, with a volume of about 63 Earths. This accounts for the surface gravity being slightly less than that on earth; an earth explorer on the surface would be much farther from the planet's center of gravity than on earth. The explorer would want to do plenty of homework before descending to the surface. Uranus is a 'gas' giant, but it probably is more icy slush than gas.
Why doesnt mercury have an atmosphere?
One word- gravity. Mercury is just simply not massive enough to generate the gravity required to hold gases close enough to the surface to create an atmosphere.
Would gravity squash the person on Uranus?
No. While Uranus has a greater mass than Earth it also has a grater radius and gravity decreases with greater distance from an object's center. In the case of Uranus, it works out that surface gravity is about 89% of what it is on Earth, so you would actually be a little bit lighter.
Why is the air so close to the surface of the earth?
The air is close to the surface of the earth because gravity holds it there
How come moons orbit Jupiter even though sun have greater gravitational pull?
If you compare surface gravity, yes the sun's gravity is stronger than that of Jupiter. But gravity decreases in strength as you get farther from the object. Jupiter's moons are close enough to Jupiter and far enough from the sun that Jupiter's gravity has more influence.
This holds a planet's atmosphere close to its surface?
Gravity holds a planet's atmosphere close to its surface. The gravitational force of the planet's mass prevents the gases in the atmosphere from escaping into space. Without gravity, the atmosphere would disperse into space.
Does uranus have volcanoes?
No. Uranus is a gas giant and doesn't have a solid surface like the rocky bodies of the solar system, such as Mercury, Venus, Earth, Mars and many moons. It is theorised to have a solid iron core, but this wouldn't allow for volcanic activity. Uranus' moon Ariel has many features that are theorised to be caused by volcanic action. These actions are caused by the massive gravity of Uranus squeezing and squashing the moon.
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.
The weight of an object is based on what?
Its mass and the gravity of the objects that are close enough to it to have a great effect on it.
How does the earth hold its Atmosphere?
Earth holds its atmosphere due to the force of gravity. Gravity pulls the gases of the atmosphere towards the surface of the Earth, preventing them from escaping into space. The Earth's gravity is strong enough to hold gases like nitrogen, oxygen, carbon dioxide, and others close to its surface.
What ryhmes with Uranus?
There are no rhymes of Uranus. Close ones are acinus, agnus, agonus.
The atmosphere is held in place by Earth's .?
