Curious about the space between the planets, he hypothesized that each gap must correspond to one of the Platonic solids: the tetrahedron, cube, octahedron, icosahedron, and dodecahedron.

出于对行星之间空间好奇，他假设每间隙都必须对应一柏拉图立体：四面体、立方体、八面体、二十面体和十二面体。

Yeah, we call it an octahedron because if you drew lines between these kind of kinematic joints here, it would create an octahedron shape.

是， 之为八面体， 因为如果你在这些运动关节之间画线，就会形成一八面体形状。
