Yes; the circle is a special case of an ellipse.
Ellipses (and, in the special case circles).
A surface whose plane sections are all either ellipses or circles. A football approaches being an ellipsoid as does a discus.

Kepler did not discover ellipses. In 1605 he discovered that the orbits of the planets were ellipses rather than perfect circles.

Johannes Kepler
Johannes Kepler replaced circles with ellipses in the heliocentric model of the universe.
The paths are "ellipses". They look like slightly "flattened" circles.
The types of conic sections are circles, parabolas, hyperbolas, and ellipses.
