Why the asteroid in this .gif take the path that it does [particularly the parts where it speeds up and then suddenly leaves]
The initial change in direction occurs because the object passes into a region of space where Earth's gravity outweighs that of the Sun. It's not a sudden change, which is why the path is curved rather than a sharp corner at this point. The final loop is special because it happened to bring the o…
The Short Answer
The initial change in direction occurs because the object passes into a region of space where Earth's gravity outweighs that of the Sun. It's not a sudden change, which is why the path is curved rather than a sharp corner at this point. The final loop is special because it happened to bring the object close to the Moon. This part is a gravitational slingshot effect – the object "steals" some angular momentum from the Moon, and the amount transferred increases if the object gets closer. With a particularly close approach, enough angular momentum is transferred to hurl the object out of the Earth-Moon system. I've been saying object because (as an aside) it's not an asteroid – it's [part of an Apollo spacecraft](_URL_0_).
