Witryna29 maj 2024 · The angle (I assumed) stays the same as a spherical Earth, but I need the axes of the ellipse. The problem becomes as follows. I have an oblate spheroid $\frac {x^2+y^2} {R_e^2}+\frac {z^2} {R_p^2} =1$ and a plane passing through the origin $n_xx+n_yy+n_zz=0$. Their intersection is an ellipse. WitrynaTo first approximation, the shape assumed by a rotating fluid (including the Earth, which is fluid over astronomical time scales) is an oblate spheroid. Is the moon an oblate …

Witryna10 lut 2024 · As already noted, it is an oblate spheroid, which is a result of the rotation of the Earth. Basically, its spin results in a flattening at the poles and a bulging at its equatorial. This is true ... In contrast to being distorted into oblate spheroids via rapid rotation, celestial objects distort slightly into prolate spheroids via tidal forces when they orbit a massive body in a close orbit. The most extreme example is Jupiter's moon Io , which becomes slightly more or less prolate in its orbit due to a … Zobacz więcej A spheroid, also known as an ellipsoid of revolution or rotational ellipsoid, is a quadric surface obtained by rotating an ellipse about one of its principal axes; in other words, an ellipsoid with two equal semi-diameters. … Zobacz więcej The most common shapes for the density distribution of protons and neutrons in an atomic nucleus are spherical, prolate, and oblate spheroidal, where the polar axis is assumed to be the spin axis (or direction of the spin angular momentum vector).
