Orbital velocity as a function of altitude
The closer an object is to the Sun the faster it needs to move to maintain the orbit. Objects move fastest at perihelion (closest approach to the Sun) and slowest at aphelion (furthest distance from the Sun). Since planets in the Solar System are in nearly circular orbits their individual orbital velocities do not vary … See more In gravitationally bound systems, the orbital speed of an astronomical body or object (e.g. planet, moon, artificial satellite, spacecraft, or star) is the speed at which it orbits around either the barycenter or, if one body is much more … See more In the following, it is thought that the system is a two-body system and the orbiting object has a negligible mass compared to the … See more For orbits with small eccentricity, the length of the orbit is close to that of a circular one, and the mean orbital speed can be … See more • Escape velocity • Delta-v budget • Hohmann transfer orbit • Bi-elliptic transfer See more The transverse orbital speed is inversely proportional to the distance to the central body because of the law of conservation of See more For the instantaneous orbital speed of a body at any given point in its trajectory, both the mean distance and the instantaneous … See more http://www.atmo.arizona.edu/students/courselinks/spring08/atmo336s1/courses/spring09/atmo656b/AppendixB_Orbits

WebSep 1, 2015 · For a geosynchronous orbit, the orbit has to take 24 hours instead of 90 minutes, because the earth takes 24 hours to spin. This happens when the circle is expanded to an altitude of about 35000 km. The Goldilocks velocity at this altitude is about 3000 m/s. This is all somewhat simplified, but the broad strokes are all there. 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.
Webcalculations). The assumptions are fairly accurate for low altitude circular orbits but may lead to significant errors for high altitude or highly elliptical orbits. Figure 1.

WebIt can be shown that a more general expression for the velocity of an orbiting satellite is = − a 1 r 2 v GmE where the mass of the satellite is negligible relative to the mass of Earth. Kepler’s Second Law can be applied (non-trivial) to calculate the position of a satellite in an elliptical orbit as a function of time.
WebMay 13, 2024 · At a carefully determined altitude and speed the upper stage engine is cut off and the stage and payload are in orbit. The exact speed needed to orbit the earth depends … WebThe escape velocity vesc is expressed as vesc = Square root of√2GM/ r, where G is the gravitational constant, M is the mass of the attracting mass, and r is the distance from the centre of that mass. Escape velocity decreases with altitude and is equal to the square root of 2 (or about 1.414) times the velocity necessary to maintain a ...
