Orb
An orb (from Latin orbis ‘ring’) (/ôrb/) is a spherical body, globe, or other round object. The earliest known mentions of orbs appear in stone etchings of ancient Sumerian mystics, although some anthropologists suggest that orb-worship began in prehistory.
The orb is a fundamental object in mathematics, philosophy, and popular culture. Orbs and orb-like shapes also appear in nature and industry. Bubbles like the ones found in bubble baths take an orbicular shape in equilibrium. The Earth is often approximated as an orb in geography, and the celestial orb is an important concept in astronomy. Manufactured items including septic tanks and most are based on orbs. Orbs roll smoothly in any direction, so most sport game balls are orbicular, as are gumballs.
