circular orbit

Perfectly round trajectory

A circular orbit is the path of an object moving around another at a constant distance, tracing a circle rather than an ellipse.

In practice, perfectly circular orbits are rare—most satellites and planets follow slightly elliptical paths.

The term appears in astronomy and spaceflight: The satellite was placed in a circular orbit around Earth.
