Who made comets predictable?

Answer 1

Comets became predictable largely due to the work of Sir Isaac newton and later astronomers like Edmond Halley. Newton's laws of motion and universal gravitation provided the framework for understanding the orbits of celestial bodies. Halley's work in the late 17th century, particularly his prediction of the return of Comet Halley, demonstrated that comets could be tracked and predicted based on their orbits. This established the foundation for modern cometary science.
