Earth hill sphere radius

WebSep 29, 2008 · It turns out that if you moved the Earth and Moon to about 40 million km from the Sun -- closer to the Sun than Mercury! -- then the Hill sphere of the Earth would be 400,000 km, equal to the moon's distance from the Earth now. That means the Moon could be stripped from the Earth by the Sun, and so then you could say the Moon orbits the … WebHill sphere: sphere of gravitational influence (limited by Lagrange points, see next view graph).

WebAug 30, 2024 · The Hill sphere, which encircles the Earth, has a radius of around 1.5 million kilometers, which is more than enough to fit the moon’s orbit. ... It is essential to keep in mind that Earth’s gravity predominates inside the Hill sphere while the Sun pushes Earth and the Moon together (almost as one entity together). WebThe zero-velocity surface is a concept that relates to the N-body problem of gravity.It represents a surface a body of given energy cannot cross, since it would have zero velocity on the surface. It was first introduced by George William Hill. The zero-velocity surface is particularly significant when working with weak gravitational interactions among orbiting … Web$\begingroup$ From messing with the sun and planets I used to think the SOI was always smaller than the Hill Sphere.
