It is said that human beings will never be able to reach another star, at least in a short period of time, and it is not always because the development of science and technology can achieve many things that we cannot achieveAt least in ancient times we never thought we could go to the moon, but now we can. <>
We're going to get to another star, which means I haven't left the solar system, because in the whole solar system, only the sun is a star, and the others are stars, the eight planets of the solar system, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and the eight planets had Pluto before it, and then it was kicked out, and as for the specific reason, no one knows. In short, there is only one star in the game, that is, the sun has eight planets, which are the ones mentioned above, and the others are planetary moons, that is, existences like the moon, and their level is ranked thirdIn order for humans to reach the stars, they need to reach something similar to the sun. <>
There is only one star in the solar system, the sun, of course, we can't get a big sun, because the sun is happening all the time, passing outward, light transfer heat our current level of science and technology, we can't get to the sun at all, we want to leave the solar system to reach the Milky Way, and find a star that we can land on in other places, its temperature should be low enough, so that our technology can reach that level,But at present, all stars emit light and heat, and even in the later stages, their temperature is still not comparable to human technology. <>
If human beings want to reach another voyage, the first thing to do is to get out of the solar system, and the second is to find high enough materials and scientific and technological equipment to resist it, so that the huge heat emitted by the sun can reach the surface of the star, and even if it is close, there is a big problem, that is, the gravitational pointBecause the Sun occupies the total mass of the solar system, its gravitational pull is much greater than that of the Earth, and ordinary flying vehicles simply cannot get close.

Because human beings are like a bundle of dust in front of the universe, human power is too small, and even the closest star to Earth is billions of light-years away from us.
-
Because it is too far away from this earth, it is impossible to reach it with the current national strength and the strength of scientific development.
-
First of all, human technology is not so developed, it has not been able to reach the landing on another star, and one star to another star, even if it is a spaceship, there are still dozens of light years, and it is still unknown whether human beings have it at that time.
-
That's because human lifespan is limited, and the maximum lifespan of a human being is more than 100 years, but if we want to reach another star, it will take at least a few hundred light-years.

Solar system. The centrosome is the Sun. Eight planets, including Earth, and a large number of dwarf planets.
and asteroids orbiting the Sun in an orderly manner.
It's easy to make the mistake of thinking that the sun is constant. It is true that the Sun is a constant reed star, but a star does not mean that the star is not moving. Like any other object, stars are in motion.
The difference is that planets, dwarf planets, and asteroids orbit stars, while stars orbit around the center of the galaxy, which in the case of the Sun, is the Milky Way.
The Sun orbits the center of the Milky Way.
The speed is actually very fast, up to 240 kilometers per second, and interestingly, we can't even notice how fast it moves. To us, the sun seems to be still. And in fact, it's not just the sun that's moving, it's moving with all the celestial bodies in the solar system.
<> whether the sun will encounter other stars.
The Sun is not the only star in the Milky Way. In fact, there are hundreds of billions of stars in the Milky Way, all of which are moving at high speeds, just like the Sun. Will these high-speed moving stars meet?
In the past, it was common for asteroids to wander into the solar system. They either settled in the solar system or were taken by Jupiter.
Massive planets of equal mass pull into the solar system. In one way or another, they have been incorporated into the solar system.
It takes about 100 million years for the Sun to orbit around the center of the Milky Way, and interestingly, it takes about 100 million years for other stars in orbit in orbit inside and outside the Milky Way to orbit the Milky Way. Why is that?
Because the Milky Way is a bar spiral galaxy.
At the center of the Milky Way is a galaxy-sized black hole that we call Sagittarius A*. The strong gravitational pull of the black hole pulls the celestial bodies around the shaper to it, and the gravitational pull of these celestial bodies pulls on the outer celestial bodies, and the entire galaxy moves. We call the populated area of the celestial body in the center of the Milky Way galaxy the center of the galaxy, and there are four spiral arms outside the center of the Milky Way, and in the process of rotational operation, each spiral arm is rotating, and each star will be convenient, so the relative position change between stars is very small, so when we look up at the starry sky.
, you will notice that the position of the star does not change much.
Unstable factors.

In the future, there will definitely be a star that will break into the solar system, because we don't know much about the universe, and no one knows what will happen before we are too late.

No! Some people have taken a look at my article "Why is a primordial nucleus not composed of two or more pure masses?" , a little"In the spirit mirror, you can sell the jasper orchid chasing the stars in Mu Lake.

Definitely not, after all, everything is kept functioning according to the law of conservation of energy, so there can be no sudden situation.

The Sun is not the only star in the Milky Way, in fact, there are hundreds of billions of stars in the Milky Way, and all stars are like the Sun, in high-speed motion.
