27 Euterpe is a large main-belt asteroid. It was discovered by J. R. Hind on November 8, 1853, and named after Euterpē, the Muse of music in Greek mythology.
Euterpe is one of the brightest asteroids in the night sky.[4] On December 25, 2015, during a perihelic opposition, it will shine with an apparent magnitude of 8.3.[5]
Euterpe has been studied by radar.[6][vague]
