Around the Sun, it may also be called a sun halo. [1] Around the Moon, it is also known as a moon ring, storm ring, or winter halo.

NASA’s Artemis program took an important step forward this weekend, with CAPSTONE finally reaching its destination—a near-rectilinear halo orbit (NRHO) around the Moon. The 55-pound cubesat ...
Two sun dogs often flank the Sun within a 22° halo. The sun dog is a member of the family of halos caused by the refraction of sunlight by ice crystals in the atmosphere. Sun dogs typically appear as a pair of subtly colored patches of light, around 22° to the left and right of the Sun, and at the same altitude above the horizon as the Sun ...
Earth-Moon Lagrangian points: a spacecraft in an NRHO around the L2 Lagrange point would have a view of Earth unobstructed by the Moon. A halo orbit is a periodic, three-dimensional orbit associated with one of the L 1, L 2 and L 3 Lagrange points. Near-rectilinear means that some segments of the orbit have a greater curvature than those of an ...
The final full moon of meteorological winter illuminated the weekend sky, and for some skywatchers across the eastern United States, it created an eye-grabbing meteorological spectacle.
