Astronomers saw some deviations from the expect orbit of the planet Uranus. Based on these deviations, some theorized that Uranus was being pulled out of its expect orbit by another planet, which turned out be Neptune.

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."


Who founded Neptune the planet?

Neptune, the planet, was not "founded" by anyone as it is a natural astronomical body. It was discovered by German astronomer Johann Galle, British mathematician John Couch Adams, and French mathematician Urbain Le Verrier in 1846 through mathematical predictions based on perturbations observed in the orbit of Uranus.


Did anyone land or just past by neptune?

no


Has anyone dug a hole in Neptune before?

No. Nobody has ever been to Neptune. Also, Neptune is a gas planet. There is no solid surface to dig a hole in.


Has anyone ever landed or shot a robot on neptune?

No. The Voyager 2 space probe flew past Neptune, but nothing has ever entered its atmosphere. Neptune has not surface to land on.
