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...

shielding. A medium Earth orbit is sometimes called mid Earth orbit or intermediate circular orbit (ICO). Two medium Earth orbits are particularly significant...

the same area. 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 approximated...

innermost stable circular orbit (often called the ISCO) is the smallest marginally stable circular orbit in which a test particle can stably orbit a massive...

Higher orbits include medium Earth orbit (MEO), sometimes called intermediate circular orbit (ICO), and further above, geostationary orbit (GEO). Orbits higher...

A value of 0 is a circular orbit, values between 0 and 1 form an elliptic orbit, 1 is a parabolic escape orbit (or capture orbit), and greater than 1...

orbits can be either open or closed. Circular orbit: An orbit that has an eccentricity of 0 and whose path traces a circle. Elliptic orbit: An orbit with...

masses orbiting each other in a circular or elliptic orbit is: T = 2 π a 3 G M {\displaystyle T=2\pi {\sqrt {\frac {a^{3}}{GM}}}} where: a is the orbit's semi-major...

a satellite's orbit from low Earth orbit to geostationary orbit. In the idealized case, the initial and target orbits are both circular and coplanar....

resultant orbit will be less than that of the original circular orbit. Thrust applied in the direction of the satellite's motion creates an elliptical orbit with...

elliptic orbit or elliptical orbit is a Kepler orbit with an eccentricity of less than 1; this includes the special case of a circular orbit, with eccentricity...

value is sometimes given the symbol q. For perfectly circular orbits, there are no points on the orbit that can be described as either the apoapsis or periapsis...

the orbit, and μ is the standard gravitational parameter of the planet (398600.440 km3/s2 for Earth); as p ≈ a for a circular or almost circular orbit, it...

can stably orbit at arbitrary distances from a central object. In general relativity, however, there exists an innermost stable circular orbit (often called...

orbit, the most significant effect is atmospheric drag. Due to atmospheric drag, the lowest altitude above the Earth at which an object in a circular...

elliptical, not circular (or epicyclic), as had previously been believed, and that the Sun is not located at the center of the orbits, but rather at one...

body is assumed rigid. Examples of circular motion include: special satellite orbits around the Earth (circular orbits), a ceiling fan's blades rotating...

r_{1}} is the radius of the initial circular orbit, r 2 {\displaystyle r_{2}} is the radius of the final circular orbit, r b {\displaystyle r_{b}} is the...

In orbital mechanics, a transfer orbit is an intermediate elliptical orbit that is used to move a spacecraft in an orbital maneuver from one circular, or...

A geostationary orbit, also referred to as a geosynchronous equatorial orbit (GEO), is a circular geosynchronous orbit 35,786 km (22,236 mi) in altitude...

Samuil Kaplan in 1949 has shown that there is a minimum radius for the circular orbit to be stable in Schwarzschild metric. An exact solution to the Einstein...
