Have you ever looked up at the sky and wondered what the Sun is ? You must have, because we cannot conceive of life without this star that presides over our galaxy. Would you like to learn more about it?
The Sun: The source of energy for all
We know that it is a star, but it is not just one of the billions that exist, it is the most important one. In fact, we usually refer to the Sun as the "King Star".
It is located 150 million kilometers from our list of zambia consumer email planet and gives its name to our system, the solar system . It is much larger than it may seem to us, and could house up to 1,300,000 planets like ours inside it, isn't it incredible?
It is estimated that it formed about 4.6 billion years ago, from a giant molecular cloud composed mainly of hydrogen and helium. This solar nebula eventually collapsed under its own gravity, and began to gain density and heat, resulting in the Sun.
that lights up our days is as follows:
Solar nebula. Formed by different chemical elements that caused a gravitational instability.
Protostar. After the collapse, a hot, dense object was formed.
Accretion disk. Made of gas and dust, it emerged as the protostar spun, causing it to grow larger and larger.
Nuclear ignition. When the temperature and pressure at the core of the protostar reached a certain point, nuclear fusion occurred. This transformed hydrogen into helium and released a large amount of energy.
Birth of the Sun. The result of all the above was a main sequence star.
In 2024, millions of years after its birth, the Sun is a G2V type star, of medium size and moderate temperature. It is still in the main sequence phase, that is, it produces energy through the nuclear fusion of hydrogen into helium. Although our Sun King is also aging, it is estimated that it will spend another 5 billion years in this phase of its life cycle.
