Orbital period and velocity
The orbital period (also revolution period) is the amount of time a given astronomical object takes to complete one orbit around another object. In astronomy, it usually applies to planets or asteroids orbiting the Sun, moons orbiting planets, exoplanets orbiting other stars, or binary stars. It may … See more According to Kepler's Third Law, the orbital period T of two point masses orbiting each other in a circular or elliptic orbit is: $${\displaystyle T=2\pi {\sqrt {\frac {a^{3}}{GM}}}}$$ where: See more For celestial objects in general, the orbital period typically refers to the sidereal period, determined by a 360° revolution of one body around … See more • Bate, Roger B.; Mueller, Donald D.; White, Jerry E.

In the case of a transiting planet, the orbital period will be known from the transit interval, so it doesn't need to be derived from the RV curve.
WebOrbital velocity is the velocity needed to achieve a balance between gravity’s pull on the body and the inertia of the body’s motion. For a satellite revolving around the Earth, the orbital velocity of the satellite depends on its altitude above Earth. The nearer it is to the Earth, the faster the required orbital velocity. WebEquation 13.8 gives us the period of a circular orbit of radius r about Earth: T = 2 π r 3 G M E. For an ellipse, recall that the semi-major axis is one-half the sum of the perihelion and the …
