[00:00:00]This story dates back to the year 1846, when an astronomer noticed that Uranus' orbit was behaving strangely. At a certain point in its orbit, Uranus seemed to move slightly away from its expected path and then return to its normal orbit. This didn't seem right to him because it went against Newton's law of gravity. The only explanation was that another planet might be affecting Uranus with its gravitational pull.

[00:00:25]However, no such planet had been discovered near Uranus. Using mathematical calculations, the astronomer predicted the exact location of an unknown planet in the sky. His calculations showed that another planet must exist near Uranus. Two years later, his prediction turned out to be correct.

[00:00:44]The newly discovered planet was named Neptune. Neptune became the first planet ever discovered not through direct observation with a telescope, but through mathematical calculation.
