The solar system
The Solar System was formed from an interstellar cloud of gas and dust, which was concentrated by gravity on the Sun, and began to rotate on itself. In the process matter was released, which continued to rotate, giving rise to the planets.
The components of the Solar System are:
The Sun is the star of our planetary system. It is located about 40,000 light years from the core of the Milky Way. AND It is a yellow , medium-sized star that contains 99.75% of the mass of the entire Solar System. Most of the rest of the mass is concentrated in eight planets whose orbits are practically circular and transit within an almost flat disk called the ecliptic plane . The Sun is very important to us because it has allowed life to exist on Earth.
The Sun is the only celestial body in the solar system that emits its own light (like all stars), due to the thermonuclear fusion of hydrogen and its transformation into helium in its nucleus, which is why it emits a large amount of light and energy. It has a surface temperature of about 5500 ºC.
There are some celestial bodies that do not meet the conditions to be called a planet , and they are called dwarf planets. They are too small and their orbits are not clear of smaller bodies. Some examples of dwarf planets are Pluto (before it was considered a planet) and Ceres (in the asteroid belt, between the orbit of Mars and that of Jupiter) .
