Approximately how many times the Moon's diameter must be stacked to span the $22^ ext{o}$ circle outward to the ring?
Answer
44 Moons
To grasp the immense angular scale of the $22^ ext{o}$ halo relative to the Moon itself, a helpful visualization involves comparing its span to the Moon's apparent size. The Moon's own diameter spans only about half a degree across the sky. Therefore, to cover the distance from the Moon's center out to the edge of the $22^ ext{o}$ ring, one would need to line up approximately 44 Moons side-by-side. This calculation demonstrates the vast physical extent of the atmospheric phenomenon that projects such a large circle overhead.
