Every planet orbiting the Sun has a set of 5 Lagrange Points associated with it, and planets orbited by satellites in roughly circular … WebL 1 is a similarly circular orbit, and according to this source, the Earth-Sun L 1 is ≈ 1.5million km from the Earth. Between circular orbits, the cheapest transfer is the Hohman transfer. According to the Wiki page, the required Δ v for Hohman-transfer orbits is Δ v = μ r 1 ( 2 r 2 r 1 + r 2 − 1) + μ r 2 ( 1 − 2 r 1 r 1 + r 2)

WebThe Earth moves at 30 km/s so from an orbit the same as Earth's you would need a 6 km/s impulse. But it takes 11 km/s to escape the Earth's gravitational pull from LEO, so you really need only sqrt (11 2 + 6 2 ) speed from LEO. That's 12.7 km/s, and since you're already going 7.8 km/s in LEO, you need a 4.9 km/s impulse.

WebFeb 14, 2024 · L2 is a point of unstable equilibrium, A craft stationed there would need many regular course corrections to maintain its position. However, there are orbits around L2 that are stable (or very nearly so). A craft in such an orbit requires far less fuel to maintain its orbit compared to a craft stationary relative to L2. WebIn the Earth-Sun system, the first (L1) and second (L2) Lagrangian points, occur at 1,500,000 km (900,000 miles) from Earth toward and away from the Sun.
