From perceiving Earth as a flat surface to discovering its true shape, close to an oblate spheroid, humans' conception of their home planet's shape and appearance has evolved over centuries.

Earth is commonly thought of as a sphere, but it's more accurate to call it an "oblate spheroid" that bulges somewhat around the equator, a bit like a satsuma. What's more, its shape is constantly ...

Vega's rapid rotation of once every 12.5 hours stretches it into an egg-like shape called an oblate spheroid. The star HV 2112 was first cataloged as a variable star in 1908 by astronomer ...

Among them, the prolate spheroid has been a commonly studied geometry, which can produce a variety of flows in the wake, including variations as an inclination angle, $\theta$, (negative pitch) varies ...

It’s actually a slightly oblate spheroid, or an ellipsoid. This means it is a little bit wider around the equator than it is tall, like a sphere that someone sat on and squashed a little bit.
