Orbit elements from velocity and altitude

Web4 rows · Calculates the orbital radius and period, and flight velocity from the orbital altitude. ... WebThe radius of an orbit with e = 0 is constant, so the orbit is a circle. The velocity is also constant: (121) # v circular = μ r. The time required to complete one orbit is known as the orbital period. Because the speed of a circular orbit is constant, the period is simply the circumference divided by the velocity: (122) # T = 2 π r μ / r ...

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 much. Being closest to the Sun and having the most eccentric orbit, Mercury's orbital speed varies from about 59 km/s at perihelion to 39 km/s at aphelion. WebThese six elements are called the “classic” orbital elements and fully describe the orbit and the position of the satellite in orbit.
