nonspherical
Lacking spherical shape
Nonspherical describes something that isn't shaped like a sphere—not perfectly round in three dimensions.
The term appears most often in scientific contexts describing particles, cells, or celestial bodies: nonspherical dust grains, the nonspherical shape of Earth.
Most real-world objects are nonspherical to some degree.
