Is orbit real or imaginary?

Can you please elaborate on the concept of orbit being real or imaginary? Is it a philosophical question or a scientific inquiry? In the realm of astronomy, orbits are understood as the predictable, mathematical paths that celestial bodies follow around a central point of attraction, such as a star. Are you referring to the validity of these calculated paths, or is there another interpretation of the term "orbit" that you're considering? Clarifying your perspective could help frame the discussion more accurately.
