Name or Adjective for Ellipse with very different (or very similar) scales
I am looking for an adjective or word to describe an ellipse (or ellipsoid, in more dims) where the length of the principal axes are of roughly the same order of magnitude $O\left(a\right)=O\left(b\right)$ (including equal, i.e. a circle).
For instance:
- $a=2,b=5$ would be something like an "isometric" ellipse (or ellipsoid)
- $a=2,b=50$ would be something like an "asometric" ellipse (or ellipsoid) since they are of different orders of magnitude
