Edegil
From Tolkien Gateway
Edegil ('Seven Stars') was a Sindarin name for Valacirca (or the Great Bear), one of the Constellations.
This name-form appears in the Etymologies s.v. OT- (OTOS, OTOK) seven (LR 379) as a Noldorin translation of the name Otselen (q. v.) but it is not used in any of the stories referring to the constellation.
