The Earth is nearly a sphere but not exactly, and its orbit round the sun is nearly
a circle but not exactly. The differences are easily measurable.
Regarding the question's second erroneous hypothesis, ball bearings, flywheels,
the evacuated chambers of particle accelerators, the figure of the primary mirrors
in Schmidt cameras, and the arc of the rainbow, are each as perfect a circle as it's
possible to measure.
