Let's summarize some of its most important aspects so that you understand what the Sun is and why it is so important:
It is a star. A celestial body that shines with its own light.
It is the closest star to Earth.
.
Its energy regulates the climate and the seasons, and influences the circadian rhythms of living beings.
It is basically composed of hydrogen and helium list of zambia consumer email that are in a plasma state due to the high temperatures to which they are subjected.
The temperature on its surface reaches 5,500º C and in the core it exceeds 15.5 million degrees Celsius.
Its approximate radius is 695,500 kilometers.
The distance to Earth is 150 million kilometers.
Its activity cycle is divided into periods of approximately 11 years. During this time, the number of sunspots and solar activity vary.
Phenomena such as sunspots, solar flares, solar storms, and solar wind occur there.
The gravity it gives off is what keeps planets and other solar bodies in orbit.
In about 5 billion years it will become a red giant and then a white dwarf. Finally, it will disappear, like all other stars.
More information about the sun
There is no doubt that the sun is fascinating, and it is an inexhaustible source of energy for humans:
Solar energy: its radiation can be used to generate thermal energy (solar thermal energy) using solar thermal panels , or electrical energy (photovoltaic energy) using photovoltaic cells.
Wind energy: the air, by changing density when it is heated or cooled by the effect of solar radiation, gives rise to wind energy, which can be harnessed using small or large-scale wind energy systems (wind turbines).
Energy from fossil fuels and biomass: Fossil fuels are deposits of organic matter of plant or animal origin that, over the course of millennia and through the action of geological agents, have been transformed into the fuels we know today: coal, oil and natural gas. Solar radiation, which is used by plants for photosynthesis, has been essential for their formation.
How does the Sun work?
The Sun is the star around which the planets of our solar system revolve and, due to the effect of the radiation that reaches the Earth, makes life possible on this planet.
The mixture of gases that compose it, added to the high temperatures and high pressures, causes a nuclear fusion reaction. Without going any further, this process is what nuclear fusion power plants try to replicate, which allow obtaining energy in a clean and unlimited way.
