The various kinds of broken and weathered rock material, such as soil and subsoil, that may overlie the bedrock are known as regolith.- Talitha (stars.astro.illinois.edu)
TALITHA (Iota Ursae Majoris). Three close (but physically unrelated) pairs of stars make the feet of Ursa Major, the Great Bear. In Arabic culture, the three represent the “leaps” of a gazelle, Talitha (Bayer’s “Iota” star) and Kappa Ursae Majoris making (and meaning) the westernmost “third leap” (the name actually coming from the number 3).
