The Norse goddess of the Sun is Sól.
Sól is the personification of the Sun in Norse mythology. Her name simply means “Sun” in Old Norse, and she is also associated with the name Sunna in Old High German tradition. The Poetic Edda and Prose Edda describe her as the daughter of Mundilfari and the sister of Máni, the personified Moon.
Each day, Sól travels across the sky in a horse-drawn chariot. The horses are named Árvakr and Alsviðr, while the wolf Sköll pursues her. This chase explains the mythological danger surrounding the Sun’s journey and culminates at Ragnarök, when the wolf is said to catch and devour her. Sól’s daughter then continues the solar course.
The goddess is sometimes called Álfröðull, a name that can refer to the Sun or its radiance. A common error is to identify Sól with Freyja, who is associated with love, fertility, and warfare, or with Máni, who represents the Moon.
