About Yildun
Yildun, Delta Ursae Minoris, is a white class A star, larger and more luminous than the Sun. It is faint to the eye, and needs a sky free of city light.
The name comes from the Turkish word for star. It lies close to the north celestial pole, so from northern latitudes it never sets, circling Polaris through the night with the rest of the Little Bear.
