Bathilde (minor planet designation: 441 Bathilde) is a large main belt asteroid that was discovered by French astronomer Auguste Charlois on 8 December 1898 in Nice. 441 Bathilde is orbiting close to a 5:2 mean motion resonance with Jupiter, which is located at 2.824 astronomical unit|AU.[2]
10μ radiometric data collected from Kitt Peak in 1975 gave a diameter estimate of 64 km.[3]
