Earth's hill sphere
WebThe Hill sphere (aka the Roche sphere) looks at things from the perspective of energy rather than force. One of the key developments initiated by Lagrange was to switch from the Newtonian focus on force to instead focus on energy. WebDec 27, 2024 · For physical situations in the spirit of Hill spheres and Lagrange points, I think the answer is always going to be: r 1 < r H < r 2 but I can't prove it, that would need math and it's too late tonight for me for …

Although it looks like one large structure, it's actually got a lot going on that you may not see if you don't look closely. WebThe Hill sphere for Earth thus extends out to about 1.5 million km (0.01 AU). The Moon's orbit, at a distance of 0.384 million km from Earth, is comfortably within the gravitational sphere of influence of Earth and it is therefore not at risk of being pulled into an independent orbit around the Sun.
