Let's say you are Spaceman Spiff, and you were on a spaceship that left the earth.
How far away from the earth would you have to be before the earth's gravity is insufficient to keep pulling you with it, and instead you begin to see the earth recede in the distance?
Does it differ by the amount of your mass? Or is it the same irregardless of your mass? i.e. if both the moon and Spaceman Spiff were stranded, they both would see the earth recede away at the same speed?
Since the gravitation acceleration of you to the earth is never 0, (gravity is endless so its like .000000000000000000~1 repeating), it would be the point where some other object overtakes the earth's acceleration on you.
Would that be the sun, or would you be drawn to something like Mars first?
If you are just looking for distance, the Suns gravity is about 28 (27.90 or something specifically) that of the Earth.
If you are looking for time from takeoff before you float you probably need to know that the Earths escape velocity is 11.2 km/s and an AU (distance between Earth and sun) is about 150 million kilometres. (149 598 000)
