WebMay 28, 2024 · The object is a small sphere, decaying naturally due to atmospheric drag, on a purely ballistic trajectory with no lift or retro propulsion. I can calculate the trajectory due to drag but I don't know how to find it's speed when it reaches the point of maximum heating, at approx 70-80 km altitude. WebEarth’s escape velocity is greater than the required place an Earth satellite in the orbit. Orbital speed is the speed needed to achieve the balance between gravity’s pull on the satellite and the inertia of the satellite’s motion. This is approximately 27,359 km per hour at an altitude of 242 km.
