List of comets with no meaningful orbit

Comets with no meaningful orbit are those which have been observed but do not have a well-defined or predictable trajectory due to factors such as insufficient observation time, perturbations by celestial bodies, or a lack of data to accurately calculate their orbits. While there may not be an official "list" specifically categorized as "comets with no meaningful orbit," astronomers often refer to comets that are poorly defined or have uncertain orbits.
