spherical

Scientists describe it as a giant spherical shell around our solar system made of icy, comet-like objects.

The shape of its hull - the part where the passengers were - was cylindrical rather than spherical so the effects of the pressure were not distributed evenly.

Titan’s hull was also an unusual shape - cylindrical, rather than spherical.

Soon after the big bang, giant spherical “halos” of dark matter would have attracted clouds of hydrogen and helium, causing them to condense into hundreds of billions of stars that would gather in galaxies.

A related study awaiting publication, she added, shows that small, spherical nanoparticles are more toxic than triangles or cubes.
