WebAt key locations in the Perseid stream, meteors may clump together thanks to gravitational nudges from what’s called a three-body orbital resonance. For one orbital period of the Perseid ... 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 also refer to the time it … 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 its primary relative to the fixed stars projected in the sky. For the case of the Earth orbiting around the Sun, this period is … See more • Bate, Roger B.; Mueller, Donald D.; White, Jerry E. (1971), Fundamentals of Astrodynamics, Dover See more In celestial mechanics, when both orbiting bodies' masses have to be taken into account, the orbital period T can be calculated as follows: $${\displaystyle T=2\pi {\sqrt {\frac {a^{3}}{G\left(M_{1}+M_{2}\right)}}}}$$ where: See more • Geosynchronous orbit derivation • Rotation period – time that it takes to complete one revolution around its axis of rotation • Satellite revisit period • Sidereal time See more
