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. WebOct 8, 2024 · 1 Answer.

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. WebThe roughly spherical shape of Earth can be empirically evidenced by many different types of observation, ranging from ground level, flight, or orbit. The spherical shape causes a number of effects and phenomena that …

In this area the object's gravity pulls more strongly than anything else; and everything else combined. The primary competition for a planet is the sun. The further you get from the sun then the weaker its gravity is.
