Ovalitäten

Ovalitäten refers to the deviation of a celestial body from a perfect sphere. While many celestial objects are approximately spherical due to gravity, they are not perfectly so. This deviation can be caused by various factors, including rotation and tidal forces. For planets, rapid rotation can cause them to bulge at the equator and flatten at the poles, resulting in an oblate spheroid shape. The Moon's ovalität is influenced by Earth's gravitational pull. This non-spherical nature has implications for orbital mechanics and the measurement of gravitational fields. The study of ovalitäten helps astronomers understand the internal structure and evolution of planets, moons, and other celestial bodies. It is a fundamental concept in celestial mechanics and geophysics.
