Imagine that we sent some ball by cannon from the Earth directly to the Sun. To reach the sun the ball should have Escape Velocity-11,2 km/sec and due to Earth’s gravity this velocity will continuously decrease until the point where the gravity of the Sun and Earth are equal. After this point the ball will simply fall on the Sun. Could you please tell me at what distance is this point located from the Earth? What do we call this point? This point and all other points nearer (relative the Earth) are inside some imagery sphere, what do we call this sphere? Is it Hill sphere?
