The force of attraction between the Earth and Sun, known as gravity, keeps the Earth in its orbit. The force can be calculated as:
F = G m1 m2 / r2
With the two masses m1 m2 in kilogrammes and the distance r in metres, and the constant G the universal gravitational constant 6.670 x 10-11, then the force is calculated in Newtons.

How does gravity affects uranus?
Gravity on Uranus is similar to other planets, as it is determined by the planet's mass and size. Objects on Uranus experience a gravitational force that is around 91% of Earth's gravity. This force keeps the planet's atmosphere in place and influences the orbits of its moons.
Why does the atmosphere of the Earth float above the planet's surface?
The atmosphere of Earth is held in place by gravity. Gravity pulls air molecules towards Earth's surface, creating atmospheric pressure that keeps the atmosphere from floating away into space.
What are the two factors that keep the earth orbiting the sun and the moon orbiting the earth?
Gravity and Inertia. The gravity keeps the planet, moon etc. going in a circle and inertia keeps it going (inertia is the tendency of a moving object to continue in a straight line or a stationary object to remain in place. If there was no gravity the planet, moon etc. would just go in a straight line but with gravity it pulls it in a circle like a string attached to an object at the center.
Why doesn't earths atmosphere get sucked into the vacuum of space?
Earth's gravity keeps our atmosphere from being pulled into space. The force of gravity pulls the gases in the atmosphere towards the Earth's surface, preventing them from escaping into the vacuum of space. Additionally, the atmosphere is held in place by the Earth's magnetic field.
Where in the universe does gravity act?
Where can you find gravity in the universe? If your feet are on the ground, then look no further! Gravity is the force that holds you to the earth. Gravity is what holds the moon spinning round the earth, and not floating away. Gravity holds the oceans on the earth, as well as the atmosphere.
What is the role of gravity in earth?
Gravity keeps things together here on Earth. It keeps the Earth together in the first place, and it keeps us on Earth. It keeps the Earth in orbit around the Sun, and it keeps the Moon in orbit around Earth.
What keeps the atmosphere around the earth?
A magnetic field holds atmosphere to the planet. Without a magnetosphere the solar wind from the sun will blow the atmosphere away. That is why our planet still has an atmosphere, we have the magnetic poles.
The atmosphere is held in place by Earth's?
The atmosphere is held in place by Earth's gravity. Gravity keeps the gases of the atmosphere from drifting off into space and creates a force that pulls them towards the planet's surface. Without gravity, the atmosphere would dissipate into space.
What is gravity and how does it affect earth?
Gravity is a force that pulls objects with mass towards each other. On Earth, gravity is what keeps everything grounded and causes objects to fall towards the ground when dropped. It also determines the weight of objects on Earth because it is responsible for the force that keeps us and everything else on the planet in place.
What effect does gravity have on the sun earth and moon?
it keeps them in place
How are people affected by gravity?
-- It keeps the Earth's atmosphere in place, thus allowing us to breathe normally.-- It keeps our feet firmly in contact with the ground, thus allowing us to walk.-- Sadly, it makes it possible for us to fall out of bed.
How does gravity affects uranus?

Why do we need gravity for life on Earth?
Gravity is essential for life on Earth because it keeps our atmosphere in place, allows water to flow, and enables plants to grow towards the sun. Without gravity, our planet would not be able to support life as we know it.
Why does the atmosphere of the Earth float above the planet's surface?
The atmosphere of Earth is held in place by gravity. Gravity pulls air molecules towards Earth's surface, creating atmospheric pressure that keeps the atmosphere from floating away into space.
The atmosphere is held in place by Earth's .?
gravity
What lets earth has gravity force?
the sun has its own gravity and that's what keeps the earth and the other plants in place as they orbit.
What does the gravity do to the atmosphere?
Answer: It keeps up from being crushed from the atmosphere around us... it also keeps us from floating away and helps keep the earth the right temp. Answer: Gravity keeps the atmosphere around the planet in the first place.
