Since it's symmetric around the origin, just scale it.
If you need a "2D" part of it, just take a slice out of it.
I'm sure you could use a parametric, an isosurface, or possibly even a
polynomial if those are 3D.
As a related aside:
In Shapes2 there's a spheroid, and in Shapes3 there's facetted sphere and ring
sphere, since those might be fun to play with in conjunction with a globe.
