In Norse mythology’s Ragnarok, the daughter of the sun goddess Sól replaces the Sun after the wolf Fenrir catches and devours her mother.
The detail comes from the Poetic Edda poem Vafþrúðnismál. In a dialogue about the world’s fate, the giant Vafþrúðnir explains that before the wolf takes Sól, she will bear a daughter who follows her mother’s path through the heavens.
This daughter therefore preserves the movement of the Sun after Ragnarok rather than becoming a separate planet or star. The passage is brief and does not give the daughter a personal name, which is why references usually call her simply the daughter of Sól.
The episode is distinct from the fate of Máni, the moon god, and from the wolf Sköll, who pursues the Sun in other Norse mythological traditions. The broader Ragnarok narrative presents the renewed cosmos as containing continuities from the old world as well as major changes.
