70 Panopaea ( / / ) is a large -ə- PAN -ə PEE main belt asteroid. Its orbit is close to those of the Eunomia asteroid family; however, Panopaea is a dark, primitive carbonaceous C-type asteroid in contrast to the S-type asteroids of the Eunomian asteroids.
Panopaea was discovered by
Hermann Goldschmidt on 5 May 1861. It was his fourteenth and last asteroid discovery. It is named after [1 ] Panopea, a nymph in Greek mythology; the name was chosen by Robert Main, President of the Royal Astronomical Society. [9 ]
The orbit of 70 Panopaea places it in a
mean motion resonance with the planets Jupiter and saturn. The computed Lyapunov time for this asteroid is 24,000 years, indicating that it occupies a chaotic orbit that will change randomly over time because of gravitational perturbations of the planets. [10 ]
