Super Battleship Reborn

Chapter 32 The Lost Star Xiao Yu did not visit Uranus, because Uranus happened to travel to the other side of the sun at this time. However, according to estimates, after another 2 billion kilometers of flight, Xiao Yu's fleet will pass Neptune when it reaches the orbit of Neptune, thus having a rare opportunity to observe Neptune at close range.

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 sphere. At the core of the sphere were three county-level spaceships. Outside, there were seventy township-level spaceships. A village-level spacecraft, like the stars encircling the moon, guards the county-level and township-level spacecraft in the center.

Each spaceship is at least 500 kilometers apart from each other. More than a thousand spaceships form a large ball with a diameter of 10,000 kilometers. Xiao Yu sits in the center of the large ball and commands a huge fleet. Traveling fast in space.

In front of the fleet, the village-level spaceship that was on guard duty sent out lasers from time to time to vaporize the asteroids that blocked the way. Xiao Yu's fleet, like a crab, rampaged in the solar system.

Ahead, the blue Neptune like the ocean has entered Xiao Yu's field of vision. Here, Xiao Yu saw the spectacular Great Black Spot on Neptune and observed Triton up close.

Triton was once a Kuiper Belt object and was captured by Neptune's strong gravity, so Triton's orbit is retrograde, and it's slowly approaching Neptune. After its distance from Neptune exceeds the Roche limit, it will be torn apart by Neptune's strong gravity, and then the fragments of Triton will hit Neptune.

It is foreseeable that this will be another huge impact event no less than the collision of the Moon and Jupiter. However, because it is too far away, it will not have much impact on the inner planets.

Xiao Yu 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.

The encounter with Neptune was just an instant. Xiao Yu not only did not stop for Neptune, but instead accelerated the speed of his fleet to 520 kilometers per second with the help of Neptune's gravity.

A month later, Xiao Yu's fleet reached the orbit of Pluto. Through the telescope, after expressing sympathy for Pluto, which is 300 million kilometers away, Xiao Yu continued to fly towards the outer solar system.

Here, it is already the territory of the Kuiper Belt. The Kuiper Belt is the main source of short-period comets in the solar system. For example, the famous Halley's Comet is believed to come from here. But Xiao Yu didn't have such good luck to meet it. Now Halley's Comet, I don't know which corner of the solar system is dangling.

Here, six billion kilometers from the sun. Looking at the sun here is only slightly brighter than looking at Venus from Earth. She has become a point of light, losing all details. But even at such a distance, she still dominates everything here. Yes, in the Kuiper Belt, Pluto, Zina, Sedna and other celestial bodies are still revolving around the bright spot in the distance together with countless icy rocks.

Here, it's cold and dark. Loneliness 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 Yu continued to move forward. In space, because the reference object is lost, it is not aware that it is moving. Xiao Yu's huge fleet was suspended in space like this, without any movement.

Xiao Yu has been observing the strength of the solar wind. During the nine-month long journey, Xiao Yu saw that the speed of the solar wind was slowly decreasing, which meant that the influence of the sun on this place was getting weaker and weaker.

Gradually,

Gradually, the speed of the solar wind decreased from a few hundred kilometers per second to below the speed of sound at 340 meters per second. Xiao Yu knew that he had come to the edge of the solar system.

Outside, it will be the world of infinite interstellar medium. The sun, with its powerful energy and the solar wind, has opened up a world of its own in the interstellar medium, and the place where Xiao Yu is will be the border between the solar empire and the interstellar medium.

Here, is the heliopause. 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. The solar wind will have a fierce confrontation with the interstellar medium here. There will be countless particles colliding violently in places where Xiao Yu cannot see. The temperature here is as high as several thousand degrees Celsius.

Yes, it is cold and dark here, and humans will be instantly frozen into ice cubes here, but the temperature here is indeed as high as several thousand degrees Celsius.

Temperature is just a physical quantity that measures the intensity of thermal motion of the molecules of an object. The matter here is too small and too thin, so although the temperature is high, it has no effect on Xiao Yu. Just like in the ionosphere of the earth, the temperature is as high as more than 1,000 degrees, but there are still many artificial celestial bodies flying freely there.

Here is the final battlefield. In the confrontation with the interstellar medium, the solar wind was crushed. Xiao Yu knew that after passing through this place, the sun would have no other means to influence this place except gravity.

It took Xiao Yu two days to pass through here and through the heliopause. Looking at the detector, the number of high-energy charged particles from the sun gradually decreased and eventually disappeared. Looking at the bright spot in the distance that was already somewhat dim and not much different from the rest of the stars in the universe, Xiao Yu felt in his heart. An indescribable taste.

Mother, dear mother, goodbye, goodbye. Xiao Yu muttered to himself, with an urge to cry.

Moving on, it will be the interstellar medium, the world of hydrogen and helium from the Milky Way. The matter here is unimaginably thin, not even one atom per cubic centimeter. Such a density is equivalent to the material density of a drop of water evenly distributed in a space of five million cubic kilometers.

What greets Xiao Yu in front will be a lonely journey of more than 6,000 years in such a space.

After leaving the top of the heliosphere, Xiao Yu has been depressed for a year. During this year, Xiao Yu has been in a state of trance, and the daily operations of the fleet are all handed over to the automatic program. , Xiao Yu just looked at the direction of the sun through the telescope every day, immersed in memories and couldn't extricate himself. Fortunately, the route has already been set, and there is no need to worry about encountering an asteroid attack here, and there is no accident in Xiao Yu's fleet.

Here, the distance from the sun is already 35 billion kilometers. It takes 32 hours for the sun's light to reach here. But here, in such a distant place, Xiao Yu made a major discovery.

He found a planet.

Yes, at hydrostatic equilibrium, with enough mass to clear out the rest of the small bodies in orbit, this planet, in every way, fits the astronomer's definition of a planet.

Its mass is one-and-a-half times that of the Earth. It is a rocky planet. It revolves around the sun at an extremely slow speed, and its cycle reaches 732 years.

Looking at this planet, Xiao Yu's heart suddenly opened up and he understood many things.

Before, humans have been wondering whether there is another large planet outside the orbit of Pluto. Otherwise, there is no way to explain the strange orbits of many small celestial bodies in the Kuiper belt. Now, Xiao Yu finally found the answer.

Here, there is indeed a large planet. But because it is too small and it is too dark, humans have never been able to find it.

Xiao Yu named the planet Lost Star. Here is a lost land, and there has never been any trace of it in human written records.

Xiao Yu put a lot of energy into 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 liquid suspected of liquid nitrogen and a white solid like water ice. This suggests that, given the right temperature for water ice to melt and liquid nitrogen to sublimate, it could also have an Earth-like atmosphere.

On the lost star, there are mountains, which prove that it once had crustal movement, and there is crustal movement, which proves that it has a liquid, hot core. Perhaps, it will also have volcanic eruptions, hot springs caused by geothermal heat, and there may be life in the hot springs.

Xiao Yu has a lot of thoughts in his heart.

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 give up his research on it regrettably.

The discovery of the lost star saved Xiao Yu from the downturn, and Xiao Yu regained his spirit and had the desire to explore.

The compilation work of Qunying Canglu has restarted, and research on projects such as ultra-long-distance communication, anti-gravity technology, and a new generation of spacecraft engines has also been put on the agenda. The research on physical theory is also in full swing, and even the huge amount of scientific calculation has already scheduled the calculation schedule of the main computer to three hundred years later.

That is to say, the data required for calculation now is enough for the main computer to operate at full capacity for three hundred years. This result made Xiao Yu smile bitterly. However, there is time in the journey, but Xiao Yu is not in a hurry.

Time, in this lonely but full state, slowly slips away. Since his encounter with the Lost Star, Xiao Yu has never encountered any substance. This situation has been maintained for six hundred years.

Six hundred years later, Xiao Yu arrived at a place.

Here, is the Oort cloud, here, one light-year away from the sun.
