(geometry) A portion of the surface of a sphere cut off by two vertical planes through the centre of the sphere.
The two great circles are shown as thin black lines, whereas the spherical lune (shown in green) is outlined in thick black lines. This geometry also defines lunes of greater angles: {2}π-θ, and {2}2π-θ.

(geometry) A portion of the surface of a sphere cut off by two vertical planes through the centre of the sphere.
Stereographic projection of the 3-sphere's parallels (red), meridians (blue) and hypermeridians (green). Lunes exist between pairs of blue meridian arcs.
