Chapter 32: Lost Star

Chapter 32 The Lost Star Xiao Yu didn't visit Uranus, because Uranus just happened to be on the other side of the sun. However, according to estimates, after another two billion kilometers of flight, when Xiao Yu ’s fleet reached Neptune ’s orbit, they would pass by with Neptune, thus having a rare opportunity to observe Neptune up close.
At this moment, the speed of Xiao Yu's fleet relative to the sun has reached 500 kilometers per second.
During the long journey, Xiao Yu arranged the fleet into the shape of a ball. The core of the ball was three county-level spaceships. In addition, it was surrounded by seventy township-level spaceships. The village-level spaceship, like the stars and moons, will be at the center of the county and township spaceships.
Each spacecraft is at least 500 kilometers apart from each other. More than 1,000 spacecraft form a large ball with a diameter of 10,000 kilometers. Xiao Yu sits in the middle of the ball and directs a huge fleet. Rapidly moving through space.
In front of the puppet fleet, the village-level spaceships on guard missions emitted a laser from time to time to vaporize the asteroids blocking the way ahead. Xiao Yu's fleet, like a crab, rammed through the solar system.
Ahead, Neptune, blue like the ocean, has entered Xiao Yu's field of vision. Here, Xiao Yu saw the spectacular black spots on Neptune and observed Triton closely.
Neptune was once a Kuiper belt object, and was later captured by Neptune's powerful gravity, so Triton's orbit is retrograde and it is slowly approaching Neptune. After its distance from Neptune exceeds the Roche limit, it will be torn apart by Neptune's powerful gravity, and then, Triton's fragments will hit Neptune.
I can predict that this will be another huge collision event no less than the collision of Muyue. However, because it is too far away, it will not affect the inner planets much.
Xiao Xiaoyu did not slow down his fleet. Now that he has made up his mind to leave the solar system, no matter what kind of scenery, Xiao Yu can no longer stop.
Plutonium and Neptune's plutonium are only momentary. Not only did Xiao Yu stop for Neptune, but instead he used Neptune's gravity to accelerate the speed of his fleet to 520 kilometers per second.
After a month, Xiao Yu's fleet reached Pluto's orbit. After expressing sympathy for Pluto, 300 million kilometers away through the telescope, Xiao Yu continued to fly towards the outer solar system.
Here, it is the Kuiper belt. The Kuiper Belt is the main source of short-period comets in the solar system. For example, the famous Halley comet is thought to come from here. However, Xiao Yu happened to encounter it without such good luck. Comet Halley now does not know which corner of the solar system is dangling.
Here, six billion kilometers from the sun. Looking at the sun here is only a bit brighter than looking at Venus on Earth. She has become a spot of light, losing all the details. But even so far, she still dominates everything here. Yes, in the Kuiper Belt, Pluto, Zina, Sedna and other celestial bodies are still moving around the bright spot in the distance with countless cold stones.
Here, cold and dark. Solitude is the eternal melody of the universe, and light is the rare scenery in the universe.
There are at least 100 million celestial bodies scattered in this huge space. But Xiao Yu couldn't see anything. Compared to this huge space, the density of matter is really too thin.
Xiao Xiaoyu is still going forward. In space, because you lost your reference, you don't realize you are moving. Xiao Yu's huge fleet was so quietly suspended in space without any movement.
Xiao Xiaoyu has been observing the intensity of the solar wind. During this long journey of nine months, Xiao Yu saw that the speed of the solar wind is slowly decreasing, which means that the influence of the sun on this place is getting weaker and weaker.
Gradually, gradually, the speed of the solar wind decreased from a few hundred kilometers per second to a speed of sound below 340 meters per second. Xiao Yu knew that he had come to the edge of the solar system.
Outward, it will be the world of infinite interstellar medium. The sun, by virtue of its own powerful energy, uses the solar wind to open up a world of its own in the interstellar medium, and the place where Xiao Yu is located will be the border between the solar empire and the interstellar medium.
Here is the top of the heliosphere. Here, 18 billion kilometers from the sun.
Under the influence of the interstellar medium, the speed of the solar wind finally dropped below the speed of sound. Here, the solar wind will start a fierce confrontation with the interstellar medium, and there will be countless particles launching fierce collisions in places invisible to Xiao Yu. The temperature here is as high as several thousand degrees Celsius.
Yes, it's cold and dark here, and humans will be frozen into ice cubes instantly, but the temperature here is indeed thousands of degrees Celsius.
The temperature is only a physical quantity that measures the violent degree of thermal movement of objects' molecules. The material here is too little and too thin, so although the temperature is high, it has no effect on Xiao Yu. It's like the earth's ionosphere, the temperature is over 1,000 degrees, but there are still many artificial celestial bodies flying freely there.
Here is the ultimate battlefield. In the confrontation with the interstellar medium, the solar wind failed. Xiao Yu knows that after passing through here, the sun will have no other means to influence the place except gravity.
Xiao Xiaoyu spent two days walking through this place and through the top of the heliosphere. Looking at the detector, the number of high-energy charged particles from the sun slowly decreased and eventually disappeared. Looking at the bright spot in the distance, which was already a little dim, and was not much different from the rest of the stars in the universe, Xiao Yu's heart had An unspeakable taste.
"Mother, dear mother, goodbye, goodbye." Xiao Yu muttered to himself, with an urge to cry.
Plutonium moves on, it will be the interstellar medium, that is, the world of hydrogen and helium from the Milky Way. The material here is so thin that it is unimaginable, not even one cubic centimeter per atom. This density is equivalent to the density of a substance that evenly distributes a drop of water in a space of 5 million cubic kilometers.
He greeted Xiao Yu in front of him, and he would travel lonely for more than 6,000 years in such a space.
After leaving the top of the heliosphere, Xiao Yu has been depressed for a year. Within this year, Xiao Yu has been in a state of mental sorrow. The daily operation of the fleet is handed over to the automatic program Xiao Yu just looked through the telescope every day, obsessed with the direction of the sun, immersed in memories and unable to extricate himself. Fortunately, the route has already been set up, and there is no need to worry about encountering an asteroid attack here, and Xiao Yu's fleet did not have an accident.
Here, there is a distance of 35 billion kilometers from the sun. It takes thirty-two hours for the sun's rays to pass here. But here, in such a distant place, Xiao Yu actually made a major discovery.
He discovered a planet.
Yes, it has achieved hydrostatic equilibrium and has enough mass to clear the rest of the small objects in orbit. This planet, in every respect, meets the astronomers' definition of a planet.
Its mass is 1.5 times that of the earth. It is a rocky planet. It orbits the sun at an extremely slow speed, and its period reaches 732 years.
Looking at the planet, Xiao Yu's heart suddenly opened up and understood many things.
Before that, humans have been wondering whether there is another large planet outside Pluto's orbit, otherwise, the strange orbits of many small objects in the Kuiper belt cannot be explained. Now, Xiao Yu finally found the answer.
Here, there is indeed a large planet. But because it is too small and too dark here, humans have never been able to find it.
Xiao Xiaoyu named the planet "Lost Star". This is a lost place. It has never been seen in human written records.
Xiao Xiaoyu poured great energy into the lost star. Xiao Yu even rushed to make a detection satellite and launched it on the orbit of the lost star. In this way, even if Xiao Yu's fleet continues to leave, Xiao Yu can continue to observe the lost star.
The Lost Star has no atmosphere, but on the surface of the Lost Star, Xiao Yu observed a liquid suspected of liquid nitrogen, and a white solid like water ice ~ EbookFREE.me ~ This shows that if there is a suitable temperature for water ice Melting, liquid nitrogen sublimation, it can also have an atmosphere like the earth.
On the Lost Star, there is a mountain range, which proves that it once had crustal movement and crustal movement, which proves that it has a liquid, hot core. Perhaps it will also have volcanic eruptions and hot springs caused by geothermal heat, and there may be life at the hot springs.
Xiao Yu's thoughts are full of thoughts.
Xiao Yu's observation of the Lost Star lasted for a full year, until he could no longer receive the signal from the satellite, Xiao Yu had to regret to abandon his research.
The discovery of the lost star saved Xiao Yu from the downturn. Xiao Yu regained his spirit and had the desire to explore.
The editing and rewriting of Lu Qunying's sky record has resumed, and research on projects such as hyper-range communication, anti-gravity technology, and new-generation spacecraft engines has also been put on the agenda. The research of physics theory is also in full swing, and even the huge amount of calculations has scheduled the calculation schedule of the host computer after three hundred years.
In other words, the data that needs to be calculated now is enough for the host computer to calculate for a full 300 years at full load. This result made Xiao Yu smile bitterly. However, there was time in the journey, but Xiao Yu was not in a hurry.
In a short time, I was slowly slipping away in this lonely, but full state. Since meeting with the lost star, Xiao Yu has never encountered any material. This situation has been maintained for 600 years.
Twenty-six years later, Xiao Yu arrived at a place.
