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.

What planet was the second last to be discovered?
The planet Neptune was the second last planet to be discovered in our solar system. It was officially discovered in 1846 by Johann Gottfried Galle, based on mathematical predictions by Urbain Le Verrier.
What planet was discovered in 1846?
Neptune was named after the Greek god of the sea.
What planet was discovered before Neptune?
uranus
When were the rings on Neptune discovered?
they were discovered 17 days after the planet itself was discovered.
Why do you say that Neptune the planet was discovered by pen?
It's a long story, and to answer it, we have to go all the way back to when Uranus, the planet before Neptune, was discovered. Uranus was discovered in 1781, and astronomers started calculating the orbit it should be following around the Sun. However, within a few years, astronomers started noticing the planet wasn't quite following the orbit they'd assigned it; it was slightly out of place. No matter how hard they tried, the mathematicians couldn't manage to calculate an orbit for Uranus that fit the facts. In 1845, two astronomers, John Couch Adams in England and Urbain LeVerrier in France, working independently of each other, came to the conclusion that there must be another planet beyond Uranus, pulling on it with its gravity and affecting its orbit. They used the discrepancies in Uranus' orbit to calculate where the new planet should be, but couldn't get anyone interested for a long time. It wasn't until 1846 that a German astronomer, Johann Gottfried Galle, using LeVerrier's calculations, decided to look at the spot in the sky LeVerrier had predicted the planet should be - and lo and behold, there was Neptune! So Neptune was discovered by Adams and LeVerrier, writing down their calculations with a pen, before astronomers had ever actually seen it. That's why Neptune was "discovered by pen."

What is some info about Neptune?
The planet Neptune was discovered on Sept. 23, 1846. It was the first planet to be discovered before being seen by an actual telescope.
What planet was discovered in the 1840s?
Neptune was discovered in 1846 through observations of Uranus. Uranus' orbit was seen to appear to alter slightly through the gravitational effect of another planet, which turned out to be Neptune.
