WebJun 11, 2024 · Say that two planets are in 2:1 orbital resonance, and the innermost planet is in 3:2 (1.5:1) spin-orbit resonance, while the outermost are in 3:1 spin-orbit resonance, their rotations will be in 1:1 resonance with each other: 2*1.5:3 Every time the inner planet completes 2 orbits, it rotates 3 times - and in the same time, the outer planet ... WebAn orbital resonance happens when any two periods have a simple numerical ratio. The most fundamental period for an object in the Solar System is its orbital period, and … WebMar 13, 2024 · Because the Earth radius is 315 km, the semi great axis of the target orbit is 2115 km. Because I'll place them from a lower orbit, I'll use a resonance 2:3. Then I just have to apply that formula: D1/D2 = ratio^(2/3) With ratio = 2/3 and D2 = 2115 km, this gives: D1 = 1614.05 km. This is my semi great axis to have an orbital resonance. how to show date in outlook emails received
