Will the planets in the universe collide with each other

If the earth is very close to the other planets and they move in opposite directions, the possibility of collisions is very likely. But the fact that the earth and the planets all docilely rotate in certain orbits makes that impossible.

The moon is the closest celestial body to the earth, 384,000 km from us. The distance between the sun and the earth is 149.6 million km (imagine to walk to this fireball, it would take you more than 3,400 years). The other planets in the solar system are also very far away, and because of the gravitational pull of the sun, they all have a stable orbit. Therefore they have no chance of clashing with the blue planet.

The other stars in the universe are even farther from the earth. Biling star is the closest, 4.22 light-years from Earth, which means that from this star to Earth, light must “sluggish” takes 4 years and 3 months.

In space near the solar system, stars are on average more than 10 light-years apart. Moreover, they all move according to a certain law. The sun, like all the stars in the Milky Way, moves around the center of the system according to its own law, not chaos. Therefore, it is very unlikely that stars in the Milky Way will collide with each other.

According to the calculations of scientists, in the Milky Way, on average, it takes about one billion billion years for an interstellar collision to occur. However, the probability of comets hitting the planet is much more frequent.
