Orbital speed - Wikipedia
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 (the combined center of mass) or, if one body is much more massive than the other bodies of the system combined, its speed relative to ...
Circular orbit - Wikipedia
A circular orbit is an orbit with a fixed distance around the barycenter; that is, in the shape of a circle. In this case, not only the distance, but also the speed, angular speed, potential and kinetic energy are constant. There is no periapsis or apoapsis. This orbit has no radial version.

The value of g, the escape velocity, and orbital velocity depend only upon the distance from the center of the planet, and not upon the mass of the object being acted upon. Notice the similarity in the equations for v orbit and v esc. The escape velocity is exactly 2–√ 2 times greater, about 40%, than the orbital velocity.
Orbital velocity | Escape Velocity, Centripetal Force & Gravity ...
orbital velocity, velocity sufficient to cause a natural or artificial satellite to remain in orbit. Inertia of the moving body tends to make it move on in a straight line, while gravitational force tends to pull it down. The orbital path, elliptical or circular, thus represents a …
Orbital Velocity Calculator
2024年7月16日 · This orbital velocity calculator is an advanced tool that you can use to find parameters of planet motion in an elliptical orbit (or in a circular orbit). Do you want to learn what the orbital velocity of Earth is or Jupiter's orbital period?
Escape velocity - Wikipedia
In celestial mechanics, escape velocity or escape speed is the minimum speed needed for an object to escape from contact with or orbit of a primary body, assuming: . Ballistic trajectory - no other forces are acting on the object, including propulsion and friction; No other gravity-producing objects exist; Although the term escape velocity is common, it is more accurately described as a …
Orbital Velocity: Definition, Formula, Equation And Application
2023年10月19日 · At orbital velocity, Earth’s or any celestial body’s gravitational force pulling a moon towards its center (where all its mass lies) emulates the tension you exert on one end of a string that causes a stone attached to the other end to swing in circles around you: it becomes the centripetal force that drives a moon or satellite around it.

Suppose we wish to launch a spacecraft from the surface of the Earth into a circular orbit of radius \(r\), using only a single blast of the engines on the ground and coasting the rest of the way. The initial velocity with which the spacecraft is launched is called the launch velocity, and can be found using the conservation of energy: \
Orbital Velocity: Formula & Earth Example | Vaia
Orbital velocity is the speed an object must maintain to stay in a stable orbit around a planet or star without falling into it or flying off into space.
Lesson Explainer: Orbital Speed - Nagwa
Definition: Orbital Speed Equation—Circular Orbit. In the special case of a circular orbit, an object’s orbital speed, 𝑣, is given by the equation 𝑣 = 𝐺 𝑀 𝑟, where 𝐺 is the universal gravitational constant, 𝑀 is the mass of the large object at the center of the orbit, and 𝑟 is the orbital radius.
