axisymmetric

(identical in any direction from an axis)

An object is axisymmetric if it has an axis from which the object is the same in any direction. A disk, a sphere or cylinder is axisymmetric but a cube is not.

In astrophysics, a galaxy, a circumstellar disk, or planetary rings as Saturn's may be virtually axisymmetric or mostly or generally not, as may be a minor planet such as an asteroid.
