Some stars are millions of light-years away from Earth. How do scientists calculate this distance?

In the past, mankind's understanding of the universe was very limited. However, with the development of technology and the continuous exploration of scientists, we have gradually been able to understand the mysteries of the universe. We mainly use astronomical telescopes to observe the celestial bodies in the universe. These telescopes can magnify and clearly observe images of distant celestial bodies and transmit these images to detectors on the ground or in space. For example, we can now use space probes such as NASA's Voyager 1 and Voyager 2 to obtain images of galaxies and planets millions of light-years away from Earth. These probes transmit images through radio waves and it takes a long time for us to see these images. Although the universe is far away from us, scientists are still exploring and discovering new mysteries of the universe. With the continuous development of technology, we will continue to explore the universe and understand more mysteries of the universe.

The distance between Earth and the Sun was about 1.5 billion light years. The speed of light traveling in vacuum is about 300,000 kilometers per second, so a light year refers to the distance that light travels in a year, which is about 946 trillion kilometers. The distance between the earth and the sun is about 1.5 billion light years. This figure is calculated according to the relative position between the sun and the earth. Because it takes about 36525 days for the earth to orbit around the sun, the distance that light travels in a year is about 300,000 kilometers. Therefore, the distance can be divided by 36525 to get 1.5 billion.

The distance from Earth to the Moon was about 384,400 kilometers.

The protagonist transmigrated to another world and obtained the legacy system of the previous transmigrator. He could summon players to build a sanctuary from scratch. As for the workers, they started from the acquaintances in the chat group before they transmigrated. From four to six to thirty, the prototype of the base was basically completed. They began to contact and fight the mutated humans and brought back an injured female mercenary. [Why I'm reading this book: The style of the novel is more relaxed and funny, which plays down the cruelty of the apocalypse.] It could be said that the players were quite well-shaped. At least, they were remembered by others. They were not the faceless so-called "Fourth Calamity" workers. Furthermore, it was very detailed and reasonable to use modern technology to restore production from scratch in the apocalypse. It had the taste of doomsday survival guides like "Friends of Military and Civil Talents","Militia Military Training Manual","One Hundred Thousand Whys", and "Veterans Getting Rich Manual". Why not read this book: Many people feel that no one will play this kind of realistic game with a bunch of players, and they are very disgusted with treating players as livestock. This is a matter of opinion. Secondly, it can be said that the half-system robot is too humanoid. It also depends on how much one accepts it. I personally don't like it. In general, the grain would be evaluated according to the situation. "Red Heart Sky Patrol":"Red Heart Sky Patrol" was a Xianxia novel that made people's eyes light up.

I really like the writing style and the characters in this book. The author's foundation was very solid. The characters were vivid and full, and the feelings were sincere and delicate. Even though the name was very serious, it was really fascinating after reading it. The protagonist Jiang Wang and his sister Jiang Anan had experienced a great change. By chance, they embarked on the bumpy road of becoming stronger. The story took place in the ancient times, and the demon race and the dragon race had already disappeared. The era of the Great Divine Dao was already like smoke, and the era of the peak of flying swords had also fallen…What happened in this world? Who would listen to the truth of history? Thousands of miles of mountains and rivers are painted with corpses, and hundreds of years of heaven and earth are painted with hungry tigers. The protagonist Jiang Wang had a pure heart and took it as his duty to patrol the sky. The ending of the book made both the author and the readers feel uncomfortable. After looking for the Xianxia literature, I read about 20 chapters and felt that it was very good. Even though the name was very serious, the content was very attractive. [Haha, I was wrong. This book is really good. I strongly recommend it!] P.S. It's too good. I've been reading this book for the past few days. I've almost finished reading the 357,000 novel in ten days. There are still 87 chapters left. I can't bear to read it anymore... In the past week, he had read 3158 minutes and had been reading this book. It could be considered as a record for him. He wanted to remember it. Ring of Destiny: Keyword: Bestie Lord 2 do not say anything else With this name this author Full of expectations, okay "Great Ming State Preceptor":"Great Ming State Preceptor" was a novel with a strong story. The author's writing style was excellent, making people feel as if they were in the setting of the Ming Dynasty. The protagonist traveled to the early Ming Dynasty (Yongle) and was ready to mess things up. However, he unexpectedly stood in the perspective of the torrent of history and spoke all kinds of truths, changing history and leading the enlightenment of that era. The author used plagiarism to attack the ancient society, quoted many classics and ancient documents, and taught the emperor of Ming Dynasty in the form of a small classroom. He taught courses such as biochemistry, economics, and the history of civilization development, which shocked the civil and military officials. It was easy for the readers to substitute themselves into the characters who were listening to the lecture in the novel, and they would get a sense of satisfaction from the characters 'shock, realization, and other emotions. This book was not just a cool novel. The author had a strong understanding of character creation and emotional substitution, so readers were easily attracted to it. Even though some of the plot was brainless, and the emperor and ministers in the novel were completely centered on the protagonist, overall, this book was a standard brainless novel. It was readable and had a certain level of knowledge, so it was quite interesting to read. I highly recommend this book and give it five stars! Chapter 16:"Ascending on a New Day": Otaku Pig's New Book. The Second Chapter Begins to Be Awesome. The Old God Is Strong 17:"Who's Going to Fall in Love After Being Reborn": A very good urban life novel. It's more about love. The female lead is a little afraid of society, but she can poke people's lungs. It's a little funny and casual. I recommend it. "Deep Sea Ember": -[Continuing-]--Top 3500 likes next time! Although his works were mainly fantasy and science fiction, the scenes he wrote were very realistic and the details were handled quite well. This book was no exception. At the beginning, he wrote the scene where the protagonist was in an abnormal space very well. The subsequent scene changed to the process of the ship without being abrupt. His description of the characters 'expressions and language was not inferior. Every sentence he wrote fit the atmosphere at that time, and it would not make people feel out of character or confused. The book combined elements such as strangeness and navigation. At the same time, in the strange atmosphere, it was mixed with the usual serious humor of the distant pupil. Especially the pigeon that appeared later, it made people laugh and cry. What was even more interesting was that the appearance of such a humorous plot in the Distant Pupil Book did not affect the perception of the book and did not make people feel fragmented. The book's worldview structure was also very outstanding, and the distant pupil described the worldview bit by bit in the plot, so there was no need to spoil the story here. Overall, this book was a top-notch work. Whether it was the character creation, the worldview structure, or the control of the rhythm, it was all first-class. It's getting better. I recommend it. "Cultivation in the Chaos of the Demonic Martial World". Keyword: [Heaven Crossing],[Carefree Dao],[Decisive Killing] Ranking index: [A recommendation of the same kind: I, an immortal cultivator in my twilight years, will live forever.] Reading Notes: Wenchao's products were definitely of high quality. The main world cultivated, while the sub-world cultivated blood and martial arts. It was similar to the main world's body cultivation. They used the flesh and blood of demons and devils to make tonics to nourish themselves. The resources of the two worlds could be transferred and used. Although there were only two worlds at the moment, according to Wenchao's style, it would definitely turn to the heavens in the later stages. It was important to note that there were many debuffs on the main character in the early stages. When he entered the sub-world, he was inferior to others. When he reached the late stage of the foundation establishment stage, he failed to break through. If he read too many genius books, then this book's impression was not bad. Moreover, unlike the previous books, there was a female protagonist plot in the early stages. Words of recommendation: Fang Xi wore it, and it was the second time! In the cultivation world, I was a yes-man, but in the Otherworld, I was a punching bag! "Who told him to cultivate!" [Lezi Xiuxian]"I have repeatedly stressed that the ethos of the cultivation world has always been crooked. I didn't lead it astray. It is said that history books are written by the victors. Then why are there always people framing me after I win? "Sword Immortal Lu Yang said this to the reporters, expressing his anger. The next day.
