núnun

Núnun is a term sometimes used to refer to the constellation traditionally known as Lepus. Lepus is a constellation situated on the celestial plane, located south of Orion. Its name is Latin for "hare." It is one of the 88 modern constellations recognized by the International Astronomical Union.

The constellation Lepus is relatively small and not particularly bright, meaning it can be difficult to spot without a clear, dark sky. It is best observed during the Northern Hemisphere's winter months, when it is high in the sky alongside its more prominent neighbor, Orion the Hunter. In ancient lore, the hare was often depicted as being hunted by Orion.

The brightest star in Lepus is Arneb, a yellow supergiant. Other notable stars include Nihal and Sadaljabah. While Lepus itself does not contain any prominent deep-sky objects like bright nebulae or galaxies, its location near the rich celestial wonders of Orion and the Milky Way makes it a visually interesting area for stargazers. The history of its naming and association with Orion is a recurring theme in classical mythology.
