Even if you do not like traveling and stay at home, you still travel much further than you might think.
Any person on Earth, even if he stays motionless all his life at home, will still travel. So, what is the average distance a person can cover in his life? The answer depends on whether you consider the Earth as your vehicle. Space.

If we talk about the distance on Earth, which an average person overcomes in his life, then it ranges from 50 to 80 thousand km. Although some people who are especially fond of travel overcome much more. For comparison, the length of the Earth’s equator is approximately 40 thousand km.
The Earth makes a full rotation around its axis in 24 hours, which means that every person on the planet rotates with it at a speed of 1500 km / h. This means that, on average, over 80 years of their lives, each person travels a distance of approximately 1 billion km.

In addition to the fact that the Earth rotates around its axis, it also rotates around the Sun at an average speed of 30 km/s. That is, in 80 years of life, each person makes a journey of 80 billion km.
At the same time, the Earth moves in space as part of the solar system when the Sun rotates around the center of the Milky Way. Our star completes such a revolution in the so-called galactic year, and it corresponds to 230 million Earth years. For comparison, life on our planet arose about 17 galactic years ago, and the Sun will die in about 25 galactic years. Due to the movement of the Sun in orbit around the center of our galaxy, each person overcomes 600 billion km in 80 years.

But the Milky Way also does not stand still and moves through space. First, all galaxies are moving away from each other due to the expansion of the universe. Secondly, each galaxy has its own motion – the so-called peculiar velocity. Now the Milky Way is approaching the Andromeda galaxy and the total gravitational influence of the two galaxies is enough to overcome the influence of the expansion of the Universe. Therefore, after about 5 billion years, two galaxies will collide and begin to turn into one galaxy.

In addition, the Milky Way is heading towards the Virgo Cluster, which is a huge cluster of galaxies 65 million light-years away. The Virgo Cluster itself and all the surrounding galaxies are moving towards the Great Attractor, a gravitational anomaly that is the center of our supercluster of galaxies called Laniakea. As a result of this movement, over the course of 80 years of life, each person moves about 1.5 trillion km.
Focus already wrote that scientists told which planets are the largest in the known universe. Astronomers have already discovered planets that are twice the diameter of Jupiter and more than 10 times their mass. But there is a limit to how big planets can be.
Also Focus wrote about how the Webb Space Telescope sent back to Earth a picture of the heaviest cluster of galaxies from the early Universe. It existed when our cosmos was 6.4 billion years old.
