Will the Milky Way and Andromeda collide? What galaxies will form after the collision? Will the planets in our galaxy collide with each other then? How far are we from the fairy system?

The Milky Way and Andromeda will contact in 5 to 6 billion years, and the whole collision process will last for 1 100 million years, and the original structures of the two galaxies will completely collapse. During the collision, a large number of stars and nebulae will be thrown out of galactic space. The two galaxies will eventually merge into one, and the new galaxy Andromeda (which scientists temporarily named Andromeda) will become a huge elliptical galaxy without any spiral arms or vortex shapes.

The process of galaxy collision is fierce, but when it is magical, the stars themselves don't collide, they all pass by each other and are far apart. The probability of a star colliding with another star is almost zero. However, the gas and nebula in the two galaxies will rub against each other and heat up and eventually ignite, and the gas in the colliding galaxies will emit white-hot light. If you are on the earth at that moment, you will find that the universe and sky are burning at some point. Although the burning light comes from outside the solar system, it will have disastrous consequences on the earth's ecology, because it will interfere with the day and night system, and the white-hot light will release a lot of light and heat to the earth, leading to the collapse of the ecosystem. But the solar system itself will not be destroyed.

We are 200 light years away from the Milky Way, and the Milky Way and Andromeda are approaching at a speed of 400,000 kilometers per hour. However, the biggest threat facing the earth is still the sun, which will become a red giant in 5 billion years, and the earth will be swallowed up by the sun. Of course, these things happened billions of years later, so we don't need to panic now.
