Chapter 470： Star

Remember in one second【】

What Ye Xuan said to the sisters was a little stunned. They all looked at Ye Xuan with stunned eyes. After a long time, they reacted and said in amazement:

"Brother, how do you know so much about the stars?"

"That's right, brother, you know all the companion stars and distances of Sirius, have you learned it?"

"I'm so stupid to hear it. It's the first time I know that there are so many things about the stars, and I haven't understood it normally."

"Me too, I understand only after listening to my little brother."

Ye Xuan smiled and said with a triumphant expression:

"I usually watch this aspect. I remember most of the stars in the sky."

"Really? Come here, brother, help me see what this star is, it's so beautiful!"

Fifth Sister Ye Fei showed a surprised expression upon hearing Ye Xuan's words, holding the astronomical telescope in one hand, and beckoning to Ye Xuan in the other, as if she couldn't wait.

The other sisters also did the same. When Ye Xuan said this, they all started gearing up, waiting for Ye Xuan to explain to them.

Ye Xuan didn't care, but walked up leisurely, came to the astronomical telescope, and was picked up by the fifth sister Ye Fei, and when he looked through the astronomical telescope, he saw a beautiful star.

After a short glance, Ye Xuan jumped down and watched the fifth sister Ye Fei explain:

"This star is called Canopus, or Carina a, and is about 310 light-years away from the solar system. Bright visual magnitude -0.72, absolute magnitude -5.53... I won't talk about these data."

"The brightness of this Canopus is second only to Sirius among the stars, and is the second brightest star in the sky."

"In the south, every year on the night of the second lunar month, after you find Sirius just south, you can find it just above the horizon."

"Theoretically, people south of 37 degrees north latitude have the opportunity to see it, but the length of time they see it varies. But considering factors such as ground fog and obscured vision, it is "real" to see Canopus far south than 37 degrees north latitude."

"Canopus is a lucky star in the eyes of the ancients. In the East, it is known as the Antarctic Immortal Weng. It has a good temperament, and there is also a saying of longevity, but it does not mean the life of the owner."

The fifth sister Ye Fei showed a "wow" expression when she heard the words. She looked up at the shining star in the night sky with her head straight and her hands pinched together on her chest. She felt like praying. .

The other sisters also showed shining eyes, and all raised their heads to look up at the birthday star with a smile on their faces.

Then he scrambled to grab the astronomical telescope, and then picked up Ye Xuan and placed it in front of the astronomical telescope, letting Ye Xuan explain them to them, looking impatient.

"That star is called Nanmen II, or Centaurus A. It is located in the constellation Centaurus. It is a triple star system and the star system closest to the sun."

"The total apparent magnitude of Nanmen II is about -0.27, and it is customarily regarded as the third brightest star in the day. Nanmen II is also known as the outermost guide of the Southern Cross. Proxima Centauri is usually considered this A member of the star system, it is only 4.24 light-years away from the sun and is the closest star to the sun."

"This one is Arcturus, also known as Tiandong, or "Dongxing". It is regarded as the imperial court of the heavenly king."...

"Arcturus is a star in the constellation of Boves, it is the brightest star in the constellation of Boves, and the brightest star in the night sky in the northern sky. The previously mentioned Sirius and Canopus are stars in the southern sky."

"Then in late May, extend along the curve of the handles of the Big Dipper and draw a large arc, and you can find a bright orange-red one in the starry sky near the zenith. Bright star-big horn. There are 5 small stars of magnitude 2 and 3 in the north of the big horn, arranged in the shape of a kite or sail together with the big horn."

"Next, this is the constellation that you are all interested in. Yes, it is Vega. I have to say that the fourth sister has a very accurate vision of the stars. You found the Vega."

"Vega, also known as Vega One or Lyra A, is the brightest star in Lyra, about 25 light-years away. It is a flat spherical star with a pale pink north pole and a blue-white equator. Look She has a beautiful name, and she is from the Weaver Girl and Lyra, and the color is also very beautiful."

"Vega ranks fifth in brightness in the night sky, and is the second brightest star in the northern hemisphere, second only to Arcturus. Like Arcturus and Sirius, it is one of the brightest stars near the sun."

"Okay, the star of the last eldest sister has a lot to say. This star is called Five Car Two, namely Auriga A. It is the brightest star in Auriga and the sixth brightest star in the sky, second only to the northern hemisphere. Sirius, Arcturus and Vega are the fourth brightest stars in the northern sky."

"Its English name is derived from Latin, the original meaning is little goat. Bayer nomenclature designates it as a star, abbreviated as aaurigae, aaur or aaur."

"Although it appears to be just a star to the naked eye, it is actually a star system, two pairs of stars consisting of 4 stars, which is very strange."

"The two large and bright g-type giant stars in the first pair are each 10 times the diameter of the sun and 2.5 times the mass of the sun. They orbit each other in very close orbits."

"The names of these two stars are Wucheeraa and Wucheerab, and they will gradually cool and expand in the future and evolve into red giant stars."

"The second pair is about 10,000 astronomical units away from the first pair, and both are dim, low-mass, and relatively low-temperature red dwarfs."

"Their names are five cars two h and five

With these words, I was stunned again to my sisters. They all stared at Ye Xuan in a daze, with a shocked and confused expression on his face, looking at Ye Xuan as if he was looking at something.

After a long while, he was surprised and said:

"No, brother, how come you are like an encyclopedia, you know all the stars, and you know so much about them, so thorough, my goodness."

"Little brother, how do you know everything? It's like a walking encyclopedia, too powerful."

"Yes, brother, I feel that your head is like a computer. You know everything. How do you do it? You won't be an unforgettable child prodigy."

"It's horrible, my little brother, I told me that I was blinded. Only then did I know that the stars still have so many sayings and so much knowledge. It's so horrible, your knowledge."

Dear, this chapter is over, I wish you a happy reading! ^0^
