41 Daphne is a large asteroid from the asteroid belt.
The orbit of 41 Daphne places it in a 9:22 mean motion resonance with the planet Mars. The computed Lyapunov time for this asteroid is 14,000 years, indicating that it occupies a chaotic orbit that will change randomly over time because of gravitational perturbations of the planets.
In 1999, Daphne occulted three stars, and on July 2, 1999, produced eleven chords indicating an ellipsoid of 213×160 km. Daphnean lightcurves also suggest that the asteroid is irregular in shape. Daphne was observed by Arecibo radar in April 2008. Based upon radar data, the near surface solid density of the asteroid is 2.4g cm−3.
Satellite
41 Daphne has at least one satellite, named Peneius (provisionally S/2008 (41) 1). It was identified on March 28, 2008, and has a projected separation of 443 km, an orbital period of approximately 1.1 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. In Greek myth, Pēneios is the god of the river of that name, and father of Daphne.
