How does gravity affect the space station?

The International space station is constantly falling towards Earth under the pull of Earth's gravity (Just like any other object

• gravity does not stop when you reach space!). However the Station

is moving very fast horizontally and, as the Earth is a sphere, this means that as it falls its path takes it round the Earth in a circle - it is in "orbit".

This means that if you are in the space station you are falling as fast as gravity can pull you and therefore you do not feel the pull of gravity, making you weightless.
