hello guys and girls from steemit, welcome to a new blog, so let's start. The Sun is the closest star to Earth, being the center of our Solar System, where several planets (among them ours) revolve around the mentioned king star.
Given its relevance for life on Earth, today we offer a list of 5 curiosities about the Sun that are striking for anyone who is interested in knowing a little more about this giant star so important.
1- How much mass does the Sun have?
The sun is really huge. On average, the king star has 99.85% of the entire mass of the Solar System. If we put this in numbers and more precisely in kilograms, it would be 1,988,920,000,000,000,000,000,000,000,000 kilograms, 330,000 times greater than that of Earth and 3498 times greater than that of Jupiter, which is the largest planet of our planet. system.
2- The sun moves
In the school they taught us that it is the Earth that orbits around the Sun, but this does not mean that the Sun is always immobile. It is orbiting the center of the Milky Way (about 28,000 light years from the Sun) and drags the entire Solar System with it.
3- It has different layers
The great star has a complex internal structure that is distinguished by its various layers. What we can see is the photosphere, and it is heated to an approximate temperature of 5726 ºC. Below this convection zone, in which heat moves slowly from the core to the surface, the material cools and falls into columns.
Below the convection zone there is a highly radioactive region, and there heat travels in the form of radiation. In the center of the Sun is the nucleus and the temperature there is ~ 1.36 × 107 K, no less than about 15,600,729 ˚C.
4- It is responsible for the tides
On another occasion we also talked about what causes the tides and there we saw that, basically, tides are the regular and predictable movement of water due to astronomical phenomena. In trivial terms, we could say that it is an ascent or a descent of the seas and oceans of the Earth, related to the gravity and the movements of our planet, the Moon and of course, the Sun.
The first to explain the fact was the great Isaac Newton, who assured that the tides are the result of the forces of gravitational attraction that the Sun and the Moon exert on the Earth and the way in which they interact with each other.
5- It's getting hotter and hotter ... and it ends with everything
It is difficult to imagine the fall of this colossus, however, the Sun was not there forever; it was born, it is changing and, unfortunately, it is a fact that it will die destroying the entire Solar System with its fall.
Every 10 billion years becomes 10% brighter and, as this happens, life on Earth as we know it is getting harder and harder. Unfortunately, this will continue until our planet is practically water. But, luckily, there is still a long, long time.
Rennyer.
