the reason Neptune is the planet discovered by pen is because unlike the other planets, Neptune was not discovered by finding it in the night sky. After Uranus was discovered, it was seen that its orbit was different than what was predicted, and it was decided that this was because of another unknown planet's gravitational pull. Then, mathematics was used to find the other planet, Neptune.
