For geodesy, a reference ellipsoid na one mathematically defined surface wey dey approximate di geoid, wey be di true figure of di Earth, or anoda planetary body. Because of their relative simplicity, reference ellipsoids dey used as di preferred surface on top which geodetic network computations dey happen and point coordinates like latitude, longitude, and elevation dey defined.

For 1687 Isaac Newton publish di Principia wey include proof say one rotating self-gravitating fluid body wey dey equilibrium go take di form of one oblate ellipsoid of revolution wey he call oblate spheroid. Current practice dey use di word 'ellipsoid' alone instead of di full term 'oblate ellipsoid of revolution' or di old term 'oblate spheroid'. For di rare instances (some asteroids and planets) where one more general ellipsoid shape dey needed as one model, di term wey dey used na triaxial (or scalene) ellipsoid. Plenty ellipsoids don dey used with different sizes and centres but modern (post-GPS) ellipsoids dey centred for di actual center of mass of di Earth or body wey dem dey model.

Di shape of one (oblate) ellipsoid (of revolution) dey determined by di shape parameters of di ellipse wey generate di ellipsoid when e dey rotated about its minor axis. Di semi-major axis of di ellipse, "a", dey identified as di equatorial radius of di ellipsoid: di semi-minor axis of di ellipse, "b", dey identified with di polar distances (from di centre). These two lengths completely specify di shape of di ellipsoid but for practice geodesy publications classify reference ellipsoids by giving di semi-major axis and di "inverse "flattening, , Di flattening, "f", na simply one measure of how much di symmetry axis dey compressed relative to di equatorial radius: For di Earth, "f" dey around corresponding to one difference of di major and minor semi-axes of approximately . Some precise values dey given for di table below and also for Figure of di Earth. For comparison, Earth's Moon even less elliptical, with one flattening of less than , while Jupiter dey visibly oblate at about and one of Saturn's triaxial moons, Telesto, dey nearly to .

1. Wetin dem dey call di equatorial radius of di ellipsoid?
2. And wetin be di semi-minor axis?
3. Distances from where?
4. Earth's moon or Jupiter get more elliptical orbit?
5. Wetin be reference ellipsoid?
6. Wetin e be?
7. Why dem dey desire am as surface?
8. Wetin kind of computations dey happen on top am?
9. Wetin kind of coordinates dey used from reference ellipsoids?
10. Who write di Principia?
11. When?
12. Wetin term e use there?
13. Wetin be di current term now?
14. Where current ellipsoids dey centered?
