412 Elisabetha is a large main belt asteroid that was discovered by German astronomer Max Wolf on 7 January 1896 in Heidelberg. It may have been named after his mother, Elise Wolf (née Helwerth).[4] This minor planet is orbiting at a distance of 2.76 astronomical unit|AU from the Sun with a period of 4.59 years and an orbital eccentricity (ovalness) of 0.044. The orbital plane is inclined at an angle of 13.8° to the plane of the ecliptic.[1]
This asteroid is rotating with a period of 19.65618±0.00004 h. Shape models and stellar occultations provide an estimated diameter of 97+7
−14 km. Older diameter estimates range from 76.38±2.114 to 111.12±22.22 km.[5]
Notes
- ↑ Assuming a diameter of 100.94 ± 1.4 km.
