What is another term for zero gravity?

There is no such thing as 'zero gravity,' as even if you went a million lightyears away from an object, it's gravity would still have a minor affect on you. The only way to feel no gravity from an individual body such as the earth is to be in free fall. This is why the astronauts orbiting the earth dont feel its gravity, as contrary to popular belief, orbiting is actually just free falling at an angle where you constantly miss the object you are orbiting. Hope this helped!
