The true shape of Earth is called an oblate spheroid.

地真正的形状认为扁形。

Vesta is round… ish, what's called an oblate spheroid, flattened a bit like a ball someone's sitting on.

灶圆的… … 扁体，有点坐着的。

And remember, Saturn is oblate, so as the rings formed they would've felt a gravitational tug from Saturn's equatorial bulge, centering them right over the planet's midline.

记住，土扁形，所以当土环形成的时候，它会受到来自土赤道隆起的引力，使之处于土的中线上。
