Disturbances (astronomy)

Disturbances (astronomy)

They are small oscillations in the movement of a celestial body, produced by the gravitational force exerted by a nearby star.

The study of apparently anomalous disturbances is of remarkable importance, because it has sometimes allowed to recognize disturbing invisible objects and discover new celestial bodies.

It was the disturbances observed in the Uranus movement that led to the location of Neptune. Similarly, the disturbances observed in the movements of distant stars inform us of the presence of invisible companions or planets that are in orbit around them.
