How do we tell a planet is moving towards us
WebJan 15, 2024 · Earth's mass is 5.97x10^24, several orders of magnitude mroe than us. If we assume everyone jumps 40cm up at the same time, the earth would move down 3.3x10^-14m. As we fall down, the earth would also move towards us and the total displacement (after all that) will be 0. http://www.astronomycast.com/2009/12/ep-165-doppler-effect/
