What is an oblate sphere?

A spheroid is to an ellipse what a sphere is to a circle. If you rotate an ellipse around either its major or minor axis (the major axis is the one that runs from pointy end to pointy end, the minor axis is perpendicular to this, running from flat end to flat end) the three dimensional projection you produce is a spheroid. If the spheroid you produce has a shorter polar diameter than equatorial diameter, it is said to be oblate, and looks a bit like a soccer ball would if you squeezed it between your hands. The alternative, with a longer polar diameter than equatorial diameter is a prolate spheroid.


What is prolate planets?

Prolate planets are planets whose shape is elongated due to their fast rotation, causing them to be wider at the equator than at the poles. Examples of prolate planets in our solar system include Jupiter and Saturn. This shape results from the combined effects of the planet's rotation and gravitational forces.


How do cells form spheroids?

Spherical, heterogeneous aggregates of proliferating, quiescent, and necrotic cells in culture that retain three-dimensional architecture and tissue-specific functions. The ability to form spheroids is a characteristic trait of CULTURED TUMOR CELLS derived from solid TUMORS. Cells from normal tissues can also form spheroids. They represent an in-vitro model for studies of the biology of both normal and malignant cells. (From Bjerkvig, Spheroid Culture in Cancer Research, 1992)


What is the shapes of all nine of our planets?

They are 8 major planets and 5 known dwarf planets. All are approximately spherical, and a better approximation is to consider them as oblate spheroids.


Which kind of star is most likely to be part of the spheroidal population?

Old, low-mass stars like red dwarfs are most likely to be part of the spheroidal population. These stars are typically found in galactic spheroids, which are regions of galaxies composed of older stars in a more spherical distribution.

What is prolate spheroid?

A prolate spheroid is a three-dimensional shape that is formed by rotating an ellipse around its longer axis. It is elongated in shape, like a rugby ball or an American football. Prolate spheroids have two equal semi-diameters and a longer equatorial diameter.
