The floating astronaut will not even feel the effects of another planet’s gravitational pull until it comes closer to it, but gravity is always acting on them. It can take years to reach another object with a large mass in space, and therefore to reach another field of gravitational pull. Because everything is spread out in space, there are no obvious way markers and landmarks to differentiate whether our floating astronaut is moving closer or further away from a planet, asteroid or star. This is mainly thanks to the fact that space is so vast and ‘empty’ (although space is never truly empty). This means that the effect of gravity in space may be a little less obvious than it is on Earth. But the astronaut floating in space will not feel any wind/air and will not be able to see anything immediately coming closer to them.
This is made obvious by the falling, wind whizzing past you, and seeing the ground coming closer and closer. Because of this, if you were to fall from a building, gravity would act in a way on your body that draws it closer to the surface of Earth. Gravity is more obvious on the surface of Earth since the gravitational force is stronger when closer to the surface. Everything is always falling in space thanks to the constant presence of gravity. Because of gravity being present everywhere in space, our ‘floating’ astronaut is actually constantly falling. Gravity can never be completely taken away, even if an astronaut is floating aimlessly in space, they will eventually come into the gravitational field of a large object. In relation to the surface of Earth, gravity is obviously weaker the further from Earth you go, but gravity is still there in space. Gravity is a force that is very prevalent in space, even if it is not strong everywhere. First of all, there definitely is a lot of gravity in space.
