WebThe Hill sphere around the Earth has a radius of about one and a half million kilometers, which is more than enough to fit the moon’s orbit. If the Moon was further away, or if the Earth and the Moon were any closer to the Sun, then the Moon would not orbit us here on Earth. The important thing to consider is that inside the Hill sphere, the ... In the example to the right, the Earth's Hill sphere extends between the Lagrange points L 1 and L 2, which lie along the line of centers of the two bodies. The region of influence of the smaller body is shortest in that direction, and so it acts as the limiting factor for the size of the Hill sphere. ...
