Leisure little landlord

After Jiahao and Wanyu came back together, Wang Tao and Yun Feifei looked at them and smiled. Seeing this, Jiahao asked, "What are you two doing? What are you laughing at? Haven't recovered from the sweetness yet? "

Seeing this, Wang Tao immediately wanted to change the topic, so he said, "Where did you two go? We all had a good meal, and there is a meal left for you."

Seeing this, Jiahao was also afraid that Wang Tao would ask more questions, so he said, "Really, that's great, I'm already very hungry, let's eat, eat." As he spoke, he gave Wanyu a look, Wanyu understood, The two rushed in quickly.

Seeing this, Wang Tao and Yun Feifei looked at each other, and Yun Feifei said curiously: "When did the two of them become so tacit, I have never seen these two people eating so actively."

Jiahao and Wanyu didn't speak, but started to eat on their own. At this moment, Wang Tao and Yun Feifei walked in and saw how delicious the next year's food was, so Wang Tao and Yun Feifei made it and watched them eat.

Jiahao suddenly felt uncomfortable all over, so he said: "What's the situation with you two? Are you not full? Come, eat more."

Yun Feifei shook her head directly, like a rattle, Wang Tao then smiled and said, "Where did you two go just now? You haven't come back for so long. The scenery outside is very nice?"

Jiahao then looked at Wanyu and saw that Wanyu was eating with her head bowed. Jiahao didn't know what to say, but Jiahao suddenly remembered something, so he said to them, "We are blessed tonight."

Wang Tao and Yun Feifei asked curiously at the same time: "What is blessed?"

Jiahao then said mysteriously: "I know that you don't watch TV and don't pay attention to the news. Let me tell you that there will be a meteor shower at ten o'clock tonight, and the rarest and rarest thing is that you are very likely to meet a broom star. It is also me who we said Comet. Moreover. Our position is the one with the best vision in a century, and I also checked it in advance last night. How about looking at the stars together, looking at the constellations together, and waiting for the meteor shower to come together?"

At this time, when they heard that there was a meteor shower tonight, they were all very excited.They all hurriedly asked confirmingly: "Really? Will there really be a meteor shower? I have never seen a meteor shower before."

The solar system is full of dust and solid clumps called meteoroids. When these "space junk" break into the range of the Earth, they rub against the atmosphere and burn up, becoming the meteors we see every day.If the earth encounters a group of dense meteoroids (such as materials released by comets), meteor showers will occur.

A meteor shower is a special astronomical phenomenon in which groups of meteors appear to come from a point in the sky and then fall.This point or a small area of ​​sky is called the radiant point of the meteor shower.Radiant points are a perspective effect.The fundamental reason for the formation of meteor showers is due to the fragmentation of comets.Comets are mainly composed of ice and dust.The ice vaporizes as the comet draws closer to the sun.The dust particles are ejected out of the parent body and enter the orbit of the comet like the water of a fountain.But large particles remain around the parent comet to form a dust head; small particles are blown away by the sun's radiation pressure.Comet tails form.The remaining material continues to remain near the comet's orbit.Yet even small eruption velocities.It will also cause a great difference in the revolution period of the particles.Therefore, at the next return of the comet, the small particles will lag behind the parent body, while the large particles will be ahead of the parent body.When the Earth passes through the orbit of the dust tail, there is a chance to see the meteor shower.The meteor shower activity is the comet cycle.

Meteor showers are generally believed to be the result of friction between meteoroids and the Earth's atmosphere (meteoroids can be asteroids in the asteroid belt), and meteor swarms are often produced by fragments of comets.Therefore, the orbits of meteor streams are often correlated with those of comets.Swarms of meteors form meteor showers.A meteor shower looks like meteors burst and fall from a single point in the night sky.This point or this small area of ​​sky is called the radiant point of the meteor shower.Meteor showers are usually named after the constellations in the sky where the meteor shower's radiant point is located to distinguish meteor showers from different directions.

It was night before we knew it, and Jiahao Wanyu and the others had already made preparations.Because the weather at this time is a bit hot during the day, but much cooler at night, they prepared a lot of delicious food and waited for the meteor shower to come. Looking at the sky, she said, "Wow, Cowherd and Vega, Libra, and Orion are all out."

Upon hearing this, Wanyu hurriedly asked: "Jiahao, you still know astronomy, so powerful, which one is Libra? I am Libra, please show me."

Jiahao said: "I like to study astronomy very much. I feel that the world is vast and the universe is full of mysterious colors everywhere. I especially like to study these. In the summer before, I took your old house together at my house. I liked it. Take out the mat, and then lie in the yard to observe these constellations, and occasionally there will be fashion passing by."

After a pause, Jiahao pointed to the place full of stars. How did Wanyu know Libra? Jiahao said: "Libra is located in the southeast of Virgo in astronomy, and it also belongs to the zodiac constellation. Libra is considered in astrology. Most people have soft eyes, delicate facial features, and the overall appearance gives a harmonious impression. At the same time, they have a quiet personality, love peace and all beautiful and elegant things, and have good understanding. Indecision in dealing with things is their fatal flaw; the attribute of Libra is Air signs, the ruling planet is Venus.

The stars of Libra have been recognized since ancient times, but Ptolemy did not include it as a separate constellation.In the Ptolemaic constellation, the star of Libra belongs to the scorpion's claw of Scorpio, Libra a is the "north claw" of the northern claw of Scorpio, and Libra β is the "south claw" of the southern claw of Scorpio.

People regard this group of stars as a steelyard, symbolizing fairness.However, the Romans did not discover that when the sun moved into this constellation, it was around the autumnal equinox, when the day and night were evenly equinoxed, so they marked it out independently.

Now, due to the Earth's precession, the autumnal equinox has moved to the west toward the constellation Virgo.In the current era, the Sun travels in Libra every year from November 11st to November 1rd.

When everyone heard Jiahao's detailed introduction, Wang Taoyun Feifei and Wanyu were all surprised, and Wanyu's image of the plus sign was almost crazy.

At this time, Yun Feifei asked: "Then, Jiahao, I belong to the Orion constellation. Where is the Orion constellation? I really want to know where my lovely Orion constellation is. I heard that the Orion constellation is the most beautiful, right? I found it tonight. We are the happiest people in the world. Jiahao, where is it? Where is Orion?" (To be continued..)
