👤 whose
Whose calculations helped prove that comets follow precise orbits and return after long intervals?
Quick Answer
That was Edmond Halley. He calculated that the comet seen in 1531, 1607, and 1682 was the same object and predicted its return in 1758.
The Full Story
Edmond Halley applied Newtonian mechanics to comet observations and realized that several famous sightings were of the same comet. He predicted its return for 1758, and it reappeared as expected, later becoming known as Halley's Comet. Halley's work showed that comets were not random omens but regular members of the Solar System. His calculation was a landmark triumph for astronomical prediction.
