41 Daphne (play /ˈdæfn/) is a large main-belt asteroid. This dark-surfaced body is probably composed of primitive carbonaceous chondrites. It was discovered by H. Goldschmidt on May 22, 1856, and named after Daphne, the nymph in Greek mythology who was turned into a laurel tree. Daphne has been observed to occult stars three times (all in the 1990s). Daphnean lightcurves suggest that the asteroid is irregular in shape.

Satellite

41 Daphne has at least one satellite, temporarily named S/2008 (41) 1.[2] It was identified on March 28, 2008, and has a projected separation of 443 km., an orbital period of approximately 1.6 days, and an estimated diameter of less than 2 km. If these preliminary observations hold up, this binary system has the most extreme size ratio known.[3]
