For a very long time, people thought that our planet has a flattened shape and lies on 3 pillars. A person is not able to notice its rotation, being on itself. The reason for this is in size. They are of great importance! The size of a person is too insignificant in relation to the size of the globe. Time went forward, science progressed, and with it the ideas of people about their own planet.
What have we come to today? Is it true that the
earth revolves around the sun, and not vice versa? What other astronomical knowledge in this area are valid? First things first.
Along its axis
Today we know that the globe is simultaneously participating in two types of its movement: the Earth rotates around the Sun and on its own imaginary axis. Yes, it’s the axis! Our planet has an imaginary line that “pierces” the surface of the earth at its two poles. Mentally move the axis into the sky, and it will pass next to the North Star. That is why this point always seems to us motionless, and the sky as if rotates. We think that it is heaven moving from east to west, however, we note that it only seems to us! Such a movement is visible, since it is a reflection of the planet’s real revolution - along the axis.
The daily rotation lasts exactly 24 hours. In other words, in one day the globe performs one full circle on its own axis. Each of the earth's points first passes the illuminated side, then the dark side. And in a day everything repeats again.
For us, it looks like a constant change of days and nights: morning - day - evening - morning ... If the planet did not rotate in this way, then on the side facing the light would be eternal day, and on the opposite - eternal night. Horrible! Well, that is not so! In general, we figured out the daily rotation. Now let's find out how many times the Earth revolves around the Sun.
Solar "round dance"
This we also will not notice with the naked eye. However, this phenomenon can be felt. We all know what warm and cold seasons are. But what do they have in common with the movements of the planet? Yes, they all have in common! The Earth revolves around the Sun for three hundred sixty five days or in one year. In addition, our globe is a participant in other movements. For example, together with the Sun and its "colleagues" -planets, the Earth moves relative to its own galaxy - the Milky Way, in turn, moving relative to its "colleagues" - other galaxies.
It is important to know that in the whole Universe nothing is stationary, everything flows and changes! Note that the visible movement of the celestial body is just a reflection of a rotating planet.
Is the theory true?
Today, many people are trying to prove the opposite: they believe that it is not the Earth that revolves around the Sun, but, on the contrary, the celestial luminary around the globe. Some scientists talk about the joint motion of the Earth and the Sun, which occurs relative to each other. Perhaps, once world scientists will turn “upside down” all the scientific ideas of outer space known today! So, all the points above the “and” are placed, and you and I learned that the Earth rotates around the Sun (at a speed of about 30 kilometers per second, by the way), and it does a full revolution in 365 days (or 1 year), together with so on its axis our planet turns around in a day (24 hours).
