For this reason, astronomers regularly look for orbital changes each time comets return near the Sun and update those orbits as needed, leading to reference catalogs listing multiple orbits for ...

We typically think of the Oort cloud as scattered ice balls floating far from the sun, yet still tied to it gravitationally.

Space agencies have systems in place to spot, track, and forecast the future orbits of potentially hazardous asteroids.
