At the surface of the Earth, the force of gravity is defined as 1 G.
I am wondering what gravitational force the sun excerts at the distance of 1 AU (the distance Earth is at). Imagine it like this; you are in space, at a distance of 1 AU from the sun, and you have absolutely no velocity relative to the sun. At this point you would start to fall directly towards the sun, but in this case you have a platform with rockets that counteract this so that the platform remains at the same distance from the sun. How heavy would you feel when you are standing on this platform?
