The orbit of this unknown planet orbit around the sun is actually an approximate circle, which surpasses Li Mo's understanding of the planetary orbit. Due to the huge gravity of the sun, the planets in the solar system have similar elliptical orbits, and have perihelion and arihelion.

However, the planet in front of you is an approximately circle centered on the sun. It takes about 20,000 years to orbit the sun.

Li Mo looked at the orbit map on the screen and found that the entire orbit of this unknown planet was located on the outskirts of the solar system, and the closest star body to it was the outer Koiper belt.

The dark planet's surface wanders around the outer periphery of the solar system for life, perhaps the reason why this unknown planet has never been discovered by humans.

The trajectory of unknown planets has been determined. As long as they are published in a journal, after argumentation, curious astronomers will naturally look for it. After all, everyone has curiosity.

Now you only need to make a mathematical model to communicate with Professor Tian, ​​Li Mo thought to himself.

Finally all of it was done, he packed up the data and draft papers and put them in his schoolbag.

When he opened the laboratory door, Zhou Dayong stood outside and said excitedly: "Brother Mo, if you don't come out again, I will rush in even if I break Mr. Ren's ban."

Brother Qiu, who was behind him, also stepped forward and looked carefully, "It's been seven days. If I hadn't stopped him, Dayong would have rushed in on the third day."

It's been seven days? Li Mo then realized that he had been in the laboratory for 7 days and 7 nights. He looked at the concerned expressions of the two people in front of him and said, "I'm fine. I need to go to school now. Please send me a trip with Brother Qiu."

"It's really done?" In the office on the 8th floor of the Astronomy Building, Professor Tian looked at the complex mathematical equations in front of him and asked excitedly.

"You can verify it yourself, and the preparation rate reaches more than 95%. "Li Mo said confidently.

Professor Tian then added a lot of new things, "If I hadn't been afraid that Old Man Wu would cause trouble for me, I would have been thinking about digging you."

Li Mo shook his head and said with a smile: "I have only explained the operation of the astral body from a mathematical perspective. Without the astronomical data you collected, it would be impossible to do it."

"There's one more thing, I want to ask for advice."

Professor Tian nodded, "You said."

"I want to publish a paper on astronomy, but I don't know where it is better to publish it." Li Mo asked humbly.

Professor Tian’s face showed a look of asking for advice and said slowly: “If you are an internationally renowned professor, I would recommend you to publish it on Apj, A&a, MNras. These 3 books are all professional astronomy magazines in Europe and the United States, and have a great influence.”

"But if you are an astronomical researcher, I would recommend you to publish it in Nature. Nature is a compatible and accepted magazine. Its blind review system can ensure that the author of the paper is not affected by fame."

Li Mo nodded, "Thank you!" and turned around and left.

Professor Tian behind him was shocked, "Hey, I haven't finished talking yet. Beginners like you should post it in "Astronomy Fans"."

Looking at Li Mo's leaving, he murmured to himself, "Are young people nowadays so ambitious? I have been in the academic world for so many years and have never published a paper in Nature."

"On the Inevitability of An Unknown Planet in the Solar System and Its Detailed Trajectory Data"

Li Mo repeatedly considered the title of the paper and knew that if the paper was published, it would cause a big storm in the academic community. So in the paper, he discussed in detail the inevitability of the existence of this planet and gave a complete explanation of the orbit of the planet.

Relying on the skills of writing papers sent by the system, a perfect paper was soon released. Li Mo couldn't wait to mail the paper to "nature".

"Li Mo, your early graduation application has been approved. Please defend your thesis in the conference room of the Department of Mathematics tomorrow afternoon." This is the new email received by his email.

The last step to graduate early finally came, and Li Mo carefully reviewed the proposition he once published "On: "Any map can use only four colors to make countries with common boundaries embrace different colors"" completely true.

At that time, he discussed the issue of early graduation with Professor Wu. He asked the professor how to write the graduation thesis. The professor glared at him, "Please take out the thesis that proves the Four Colors Conjectures, and I see if any professor dares to pick on it."

After saying a word, Li Mo handed over the Four Colors Conjectures as his graduation thesis.

At 2:30 pm, at the conference room of the Department of Mathematics. Almost all the mathematics professors at Yan University sat in the audience. Li Mo took the paper to the podium, inserted the U disk into the computer, and opened the ppt. "Dear teachers, my thesis title is "On: "Any map can use only four colors to make countries with common boundaries embrace different colors"" the proposition is completely valid."

As he was talking about it, he played the projection of the paper in the slideshow.

"Isn't this cheating? How do you ask your students to review this kind of paper? Lao Wu." The professors in the audience saw that Li Mo actually used the four-color conjecture proof as the graduation thesis and were talking about it.

Professor Wu picked up the microphone and asked, "Did Li Mo write this thesis during his undergraduate studies?"

The professors looked at each other and said, "Yes."

Professor Wu asked again: "Is this paper of Li Mo suspected of plagiarism?"

Professor Zhong: "How is that possible? This is a paper that has been reviewed by peers in the world's mathematics community."

Professor Wu laughed: "That's all, this paper fully meets the requirements of undergraduate graduation thesis."

Professors: "Oh, who is the genius?"

As a result, during the process of explaining the entire paper, no professor asked a question. In the end, Professor Wu couldn't stand it and pointed to a symbol in the paper and said, "I think it's more appropriate for you to use a comma here."

"Haha..." The professors in the audience were amused by Professor Wu's words.

In the end, Li Mo's thesis was approved unanimously, ending his undergraduate journey.

"Can I borrow a bachelor's uniform and take photos as a souvenir?" Li Mo asked after taking the graduation certificate handed over by Professor Wu.

Professor Wu smiled and said, "Zhou Ming should have a bachelor's uniform, you can borrow it from him."

The next day, Li Mo wore a borrowed bachelor's uniform and graduation certificate, and came to the library. Ying Sasa borrowed the camera from the Photography Association and helped him take the last photo of his undergraduate career.

"Look at how this photo was taken, although it is not the season of harvest." Li Mo pupped the photo on Weibo and received countless messages in a short while.

"This is the real big guy, I graduated in my freshman year!"

"Is the diploma real? Why does it look like a prop?"

"Don't talk nonsense upstairs. The person in the photo is Li Mo, a big shot in the mathematics department. I heard from the teacher that he graduated early."

"Why is the difference between people so big? I studied hard for four years and was still worried about my graduation thesis. Others have graduated."

"This is Li Mo from our class. Professor Princeton personally visited the cottage and invited him, but he didn't even go."

"Princeton? You brag."

"If you don't believe it, we all know this."

"Awesome!"
Chapter completed!
