Orb
An orb is a spherical or circular object, often symbolizing completeness, unity, or the cosmos, as in ancient globes or planetary representations. In modern usage, it extends to everyday items like crystal balls in fortune-telling or even metaphorical descriptions in literature, adding a touch of wonder to scientific and cultural contexts.

The most perfectly spherical object ever created is a silicon-28 sphere made for the International Avogadro Project in 2019, with a diameter variation of less than 35 nanometers, which was used to help redefine the kilogram in the SI units system. This tiny orb demonstrates how modern science achieves near-perfection in mimicking natural spheres like planets.
