What is "bestla"

In Norse mythology, Bestla is the mother of the gods Odin, Vili and Vé by way of Borr, the sister of an unnamed being who assisted Odin, and the daughter or, depending on source, granddaughter of the jötunn Bölþorn. Bestla is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, the Prose Edda, written in the 13th century by Snorri Sturluson, and in the poetry of skalds.

Some scholars have theorized that Bestla’s unnamed brother is Mímir.

Bestla or Saturn XXXIX (provisional designation S/2004 S 18) is a retrograde irregular moon of Saturn. Its discovery was announced by Scott S. Sheppard, David C. Jewitt, Jan Kleyna, and Brian G. Marsden on 4 May 2005, from observations taken between 13 December 2004 and 5 March 2005.
