How many planes of symmetry does a sphere have?

Answer 1

A sphere has an infinite number of planes of symmetry. The plane must include

the center of the sphere, but it can tilt at any angle.

The question is the same as asking "How many planes can be drawn through one

point ?" The answer is: An infinite number. And as long as the point is the center

of the sphere, each plane is a plane of symmetry of the sphere.
