<em>I think that the correct answer would be the second red dot to the right. Since every other circle (except for one of course) ends up following a line that takes it back into a circle around the Earth, which signifies that it has not left Earth's orbit. However, if you look at the second dot to the right, you can see that it is the first dot to not have a line connecting it back to Earths orbital field. This signifies that the object has finally overcome Earths gravitational pull.</em>
