sphere

Globe's geometric form

A sphere is a perfectly round three-dimensional shape—every point on its surface equidistant from the center.

Balls, globes, and bubbles approximate spheres.

The word extends to domains of activity or influence: the political sphere, outside my sphere of expertise.

The celestial spheres were the concentric shells ancient astronomers believed carried the planets and stars around Earth.
