time and space

Chapter 70 Pluto

The aircraft flew alone in the vast universe, and Bai Tang's initial excitement turned into boredom.She yawned and asked Kate: "How long will it take to fly?"

"It's early!" Kate shifted her gaze from the virtual screen to Baitang, "We haven't flown out of the solar system yet. We can only reach the first space jump point after we leave the solar system. We need to go through three space jumps before we can reach it." The fringe planet of the alliance, Gait Star."

"Damn!" Baitang swears directly.Doesn't it mean that technology will develop rapidly in the future?Why is the speed of the aircraft still so low?Shouldn't it fly out of the solar system with one acceleration?

"I want to let the wind go!" Baitang retracted into the chair sadly. The driver's seat was designed according to human body, and it was very comfortable to sit on.Her eyes swept across the interior of the aircraft, and she pursed her lips.Because it is a single-person aircraft, the internal space is very small. Except for the two seats, the other space is only [-] square meters in size, most of which are filled with the "special products" of the earth - several kinds of vegetables and fruits that Baitang transplanted from the space to the earth, Kate They were all packed on the aircraft, some of them were used as food along the way, and the rest were handed over to the research center after returning to the alliance.Kate told Baitang that the research center would award a large sum of money to the discoverers who discovered new types of edible plants, and he didn't want any of this bonus, but gave it all to Baitang.

"Just wait a little longer, the aircraft will pass by the planet Pluto in half an hour, and we can rest less there." Kate comforted Baitang.

"Pluto planet?" Baitang thought for a while, "Pluto?"

"Pluto? That's a good name!" Kate praised, "This planet is covered with thick layers of ice, which is quite similar to the legendary underworld."

"Pluto is actually the name of Pluto in ancient Roman mythology on the ancient earth. He is the ruler of the underworld, the king of the underworld, and the ruler of the soul world after death. In addition to Pluto, there are Uranus and Neptune in the solar system, nine planets in the solar system They are all named after the gods of the ancient earth: Uranus, also known as Uranus, is the god of the sky in Greek mythology; Neptune, also known as Neptune, is the god of the sea in Roman mythology; It is named after Venus, the god of love in Roman mythology; the earth is also named Ers, which is not only the name of the goddess of dawn, but also the name of the first creation god of ancient Greece..."

"You know a lot about the earth?" Kate said casually.

Baitang chuckled, "I heard all of this from Little C."

Fortunately, he had an old antique from the earth as a shield, Baitang squinted his eyes, watching the little robot squeeze the watermelon juice with satisfaction.As expected of the most advanced home robot 3000 years ago, Little C's mainboard has entered many programs for making dishes and cakes and juices. During this time, Baitang was too lazy to do it, and they ate all the food made by Little C.This caused Kate to covet Little C, and proposed to buy Little C at a high price.Baitang naturally refused to agree, and Kate kept grinding and grinding every day. Baitang was annoyed, and agreed to let Little C send some recipes to Kate's personal butler robot after returning to Blue Star, thus getting rid of Kate's entanglement.Don't look at Kate's appearance of a handsome guy in cool and serious clothes, that's all to deceive outsiders, and only after getting acquainted with him will he know that this person is a rascal.

When Little C heard Baitang mention its name, his two bulbous eyes narrowed into "＾＾", put two glasses of watermelon juice on the tray, and broke it.

"Thank you, little C!" Baitang picked up a glass of drink and stroked the little robot's head with the other hand.Little C is even happier.

Kate picked up another glass of watermelon juice and took a sip, and said to Bai Tang: "I think the appearance of the robot is not important now, the important thing is the inside!"

Bai Tang replied "hehe", she had seen the photo of Kate's butler robot, it was a big beauty with a fiery figure.

Half an hour later, the spacecraft landed on Pluto, and Baitang walked out of the spacecraft wearing the special space suit Kate gave him.The space suits of the future will not be as bloated as the space suits of the 21st century. The space suits of the future will be close-fitting and comfortable, which will not only facilitate movement, but also protect against heat, cold and radiation, and generate oxygen for people to breathe, which is extremely convenient.

"This place is even more desolate than the earth!" Kate scanned the surrounding environment of the planet, and said to Baitang, "We will rest for an hour and leave in an hour."

Bai Tang nodded and started walking on the ice. She remembered a comic book she had read before, "Galaxy Railway 999", in which the terminal was Pluto.At that time, Pluto was still considered one of the nine planets in the solar system.In 2006, Pluto was expelled from the nine planets.

"Pluto is so small, how can it be called one of the nine planets in the solar system?" Kate asked after walking around and returning to Baitang with question marks all over her face.

"This has something to do with the backward astronomical technology of the people on the ancient earth." Baitang beckoned and summoned Little C to his side, "Teach Mr. Kate about the history of Pluto."

"Yes, master!" Little C excitedly accepted the task assigned by the master, slipped to Kate, and began to recite the information: "Pluto was discovered by Clyde Tombaugh on February 1930, 2 according to the calculations of the American astronomer Lovell. It was discovered that the average distance from the sun is 18 billion kilometers, the revolution period is about 59 years, and the rotation period is 248 days. The surface temperature is below -6.387°C, and there may be a layer of solid methane ice on the surface. Due to the long distance, in the early days of discovery, people wondered Almost nothing is known about Pluto. Even in the largest astronomical telescopes, it is just a point of light, so the mass of Pluto was misestimated, thinking that Pluto is larger than the earth, so it is named a large planet."

"After nearly 30 years of further observations, scientists discovered that Pluto's diameter is only 2300 kilometers, smaller than the moon. In 1978, American astronomers discovered that Pluto has satellites. This discovery gives scientists reason to believe that Pluto's actual size is smaller than that of the moon. It was originally estimated to be much smaller, even smaller than the moon. Because of its small mass, Pluto did not attract its satellites to revolve around Pluto itself, but Pluto and its satellites orbited in the middle of the two A common point of the universe is running. It’s just that ‘Pluto is a big planet’ has already been written in textbooks, and people on the ancient earth will make mistakes.”

"In 2006, the International Astronomical Union established a new definition of a planet: a planet must first be a celestial body, which satisfies Definition [-] orbiting the sun, and Definition [-] has a mass large enough to overcome solid stress to achieve hydrostatic force Balanced (nearly spherical) shape, while definition [-] empties other celestial bodies in its orbit. According to the new definition of planet, Pluto does not meet definition [-], that is, its mass is not large enough; and it does not meet definition [-] , because the orbit of Pluto crosses that of Neptune, if Pluto is regarded as a planet, then Neptune cannot be a planet. Therefore, the International Astronomical Union decided to classify Pluto and Pluto as dwarf planets and downgrade them from large planets..."

Kate sighed to Baitang: "When you arrive at Blue Star, you have to keep a close eye on Little C. The knowledge it possesses is a treasure trove for Blue Star. Historians will definitely grab Little C from you."

Baitang: "As long as you don't tell about little C, no one will rob me."

"No. The knowledge Little C possesses is very useful for understanding the ancient Earth, and it belongs to All Blue Stars."

Bai Tang said with a dull face: "I can ask Little C to copy a copy of the information for you. You can say that it was discovered on the ancient earth."

"..." Kate hesitated for a long time, "This..."

"If you don't agree, I won't let little C give the recipe to your machine butler!" Baitang threatened lightly.

"I will never reveal the existence of Little C!" Kate immediately promised that after eating the delicacies made by Little C, Kate no longer wants to eat nutritional supplements and nutritious food.

Baitang squinted his eyes in satisfaction, and said to Little C: "Little C, today's dinner is fried potato chips and shredded sweet potatoes!"

Kate's saliva dripped down: "Is there ketchup? Potato fries are best served with ketchup! Ah, what are shredded sweet potatoes? Is it delicious?"

"When Little C is ready, don't you know if it's delicious?" Baitang smiled and returned to the aircraft, and Kate hurriedly followed.

The aircraft took off, flew out of Pluto in an instant, and passed by Pluto's satellites.The satellites of Pluto are a circle smaller than the body star, and they form horns with the body star, and revolve around the same common point.

"Pluto's satellite also has a name. It's called Charon. In Greek mythology, the boatman of Hades, the king of Pluto, was responsible for ferrying the dead across the River Styx." Baitang said looking at the satellite.

"Chiron?" Kate asked strangely.

"It's not Chiron, it's Charon. Don't get confused."

"Why? I don't think there's much difference!" Kate felt that the two pronunciations were only slightly different, so there was no need to distinguish them so carefully.

"The difference is huge, Chiron and Charon are both characters in Greek mythology." Bai Tang despised Kate's ignorance, "Chiron is a centaur, a centaur. He is known for his kindness and wisdom. He plays music, chess, calligraphy and painting. , bows and arrows, swords and guns, fist fights and sumo wrestling, he is almost omnipotent and omniscient in the world of heaven and earth. He lives in seclusion in the Piliwen cave and teaches unparalleled martial arts. All his students, even if they only learn one skill, You can dominate the world. The legendary King Theseus of Athens, the demigod hero of the Trojan War Achilles, the first warrior of the Greek coalition, Hercules in ancient Greek and Roman mythology, and even almost everyone in ancient Greek mythology All heroes came from his disciples. Chiron can be said to be the ancestor of Greek heroes, and people collectively call his disciples the 'Heroes of Piliwen'."

"Charon is the god of crossing the river Styx, the son of Erebus, the dark god of the five creation gods, and Nyx, the goddess of the night. He is Hades, the king of the underworld, who is the loyal subordinate of Pluto. The satellite of the planet Pluto Naturally it is Charon Star, not Chiron Star!"
