Voyager 1 is heading towards the Milky Way at high speed, and in 200 million years it could fly back

When Voyager 1 was launched by a rocket, its speed was more than 35 kilometers per second, but at our location on Earth, the speed had to reach 42 kilometers per second in order to sail freely under the gravity of the solar system, so it was impossible to escape the solar system at first. But then, through the gravitational slingshot effect while orbiting Jupiter and Saturn, it accelerates fast enough to escape the solar system. For example, the speed of escaping the solar system near Jupiter is only 18 kilometers per second, but here, in the current position, the speed drops to 16 kilometers per second, but the speed of escaping the solar system is only a few kilometers per second.

But Voyager 1 is now 21.6 billion kilometers away, but it is also the farthest distance that the solar wind can reach at the tip of the heliosphere, the direction in which the sun is traveling. For several days, the scabbard and bow shock wave had not yet arrived. There is still a long way to go from the solar system.

Due to the width of the Oort cloud on the outer reaches of the solar system, which is separated by 2 light years horizontally and vertically, even at the same current speed, it will take Voyager 1 300,000 years to run beyond the Oort cloud. Its diameter is about 30 billion kilometers (about 200 astronomical units, one astronomical unit is the distance from the sun to the earth, about 100 million kilometers).

At that time, astronomers had long been aware of the existence of the Kuiper Belt, but it was impossible to prove it under the conditions of the time. They ** Kuiper for the reason of the band. That is, in the early stages of the formation of the solar system, more solar gravity is applied to the planetary plates close to the interior of the sun, and eventually larger planets are formed, and at greater distances from the sun, the solar gravity is relatively reduced, and the peripheral asteroids do not have enough conditions to aggregate into larger objects.

When the Kuiper Belt was discovered, astronomers were excited, thinking they had found the boundaries of the solar system. Soon, another piece of heavy news came that in the outer layers of the Kuiper Belt, our common comets are spaces made up of smaller icy objects. This is the famous Oort Nebula.

The birth of life on Earth can be said to have a lot to do with the Oort Nebula. For hundreds of millions of years, comets from the Oort Nebula have brought abundant water and organic matter to the Earth, creating a strong foundation for the birth of the Earth.

It will probably take a few decades, and there is no way to do it, because the solar system is so big.

In the early morning of September 13, 2013, Beijing time, according to the news released by NASA, Voyager 1 has been confirmed to fly out of the solar system and officially enter interstellar space!

It turned out that the vicinity of Pluto was the edge of the solar system, but it turned out that the solar system was much larger, and the traveler's energy was running out, and it was always flying with inertia, and the speed dropped down, and if it could not reach the escape speed of the sun, it would never be able to fly out.

Voyager 1 has been in space for more than 40 years, and it is also the farthest man-made object, currently about 21.6 billion kilometers from the Sun. The unmanned probe is heading into interstellar space at a speed of 17 kilometers per second, but it cannot fly to other galaxies. Because at the location of the solar system (10,000 light-years from the galactic core), the escape velocity required to escape the gravitational constraints of the Milky Way is up to 550 kilometers per second.

The Voyager 1 is nowhere near fast enough, and it doesn't have the power to do so**. As a result, Voyager 1 will only orbit the Silver Heart, and will not be able to fly out of the Milky Way and into the extragalactic galaxy. Still, it can fly to other star systems.

Voyager 1 flies in the constellation Ophiuchus, one of the thirteen astronomical zodiac constellations. Since space is empty and Voyager 1 does not fly at a specific celestial body, it will not come into close contact with other stars for a long time. Voyager 1 will only rush past other star systems, flying far past those stars.

NASA's estimate of Voyager 1's trajectory is that the unmanned probe will fly by Gliese 445, which is currently located in the constellation Leopard, in 40,000 years, when the distance between the two will be light-years. Gliese 445, a red dwarf with a mass of only one-fifth of the Sun, is currently moving towards the solar system at a speed of 120 kilometers per second and will eventually reach its closest distance of about light-years. To date, astronomers have not discovered a planet around the star.

Even if there were intelligent life in this star system, it is likely that Voyager 1 would not have discovered its existence due to its small size and distance.

If there is no chance of an accident, Voyager 1 will carry human information to roam in interstellar space forever, becoming a satellite orbiting the silver heart.

Voyager 1 has not yet flown out of the solar system. At a speed of 17 kilometers per second, it is still a long time to pass through the Kuiper Belt, about 43x24 years, and the sphere of influence of the solar system is about 2 light-years or more, so it is still too early to talk about the very solar system.

No one knows how long it will take to reach the next galaxy

Strictly speaking, it has not yet flown out of the solar system, it has left Pluto, the planetary belt that we humans have discovered and defined, and the energy it carries has been exhausted, and it may never reach the next galaxy!

There is no way to calculate the amount of time it will take.

It is estimated that it will take a long time to reach the next galaxy

There is no way to estimate this exactly, and it should take a long time, hundreds or thousands of years.

It is estimated that it will break before it flies to the next galaxy.

For a long, long time, people didn't know how big the Milky Way really was.

This should take a long time.

No one knew that it would break before it could fly to the next galaxy.
