Most starts are oblate spheres, and so yes.
Any shape is mathematical.
No shape is mathematical really unless it has been created by a mathematical formula, but is certainly a geometric shape. But anything which is a 2D or 3D shape is geometric. My improvement: A catenary curve from a mathematical equation such as cosh x, is a mathematical and natural shape. Maby each other arch can be approximated by a mathematical formula.
It is a cube.cube
A 3D five-pointed star shape is commonly referred to as a "star polyhedron" or more specifically, a "pentagram" when discussing the two-dimensional representation. In three dimensions, it can be constructed as a stellated form of a dodecahedron or as a "star pyramid." In mathematical terms, it could also be called a "pentagrammic prism" or "pentagram star solid," depending on its specific structure and geometry.
