Q&A

how far does earth’s gravity reach

The Earth’s gravitational field extends well into space it does not stop. However, it does weaken as one gets further from the center of the Earth. The Shuttle orbits about 125 mi above the surface, roughly the distance between Jackson and Nashville!

    How far away from Earth is zero gravity?

    If the earth were about 36,000 km in diameter with the same mass and length-of-day then the gravity at the equator would be zero. This is the altitude of geostationary orbits.

    How far away can the Earth’s gravity be felt?

    Strictly speaking, the Earth’s gravity will always pull on an object, no matter how distant. Gravity is a force that obeys an ‘inverse square law’. So, for example, put an object twice as far away and it will feel a quarter of the force.

    How far away does gravity reach?

    About 4.5 billion light years. Why this number? Because gravity doesn’t stop, it just gets weaker the further you are away from the source. But gravity travels with the speed of light, and since the earth was formed about 4.5 billion years ago, you would go beyond the reach of how far the earths gravity has traveled.

    Can gravity be felt everywhere?

    The gravitational force on the moon is less than on Earth, because the strength of gravity is determined by an objects’ mass. The bigger the object, the bigger the gravitational force. Gravity is pretty much everywhere. We just feel it in different ways depending on our state of motion.

    Can gravity act from a distance?

    No. The attractive force called gravity does not extend beyond galaxy groups. If you look at Newton’s Law of Universal Gravitation, you see that the force of gravity on one mass due to another mass depends on their separation r according to the dependence 1/r2.

    How far does gravity reach?

    The gravitational force acts between all objects that have mass. This force always attracts objects together, and although it is the weakest of the four fundamental forces, gravity has an infinite range.

    How far from Earth is gravity negligible?

    If we pick ϵ=0.001ms2, then for Earth, a “negligible” radius is about 6.31×108 meters, or about 1.6 times the orbital radius of the moon, and for Mars, this result is 2.07×108 meters.

    At which point of Earth gravity is zero?

    The force due to the upper half of the Earth cancels the force due to the lower half at the center of the Earth. Similarly, any force due to any portion of the Earth at its center will be cancelled by the portion opposite to it. As a result, the gravitational force at the center of anybody will be zero.

    How far above Earth before gravity stops?

    The Earth’s gravitational field extends well into space it does not stop. However, it does weaken as one gets further from the center of the Earth. The Shuttle orbits about 125 mi above the surface, roughly the distance between Jackson and Nashville!
