The Solar System is our \u201ccosmic neighborhood,\u201d so to speak. It is the entire region dominated by our central star, our Sun, along with all the celestial bodies that revolve around it. In turn, the Solar System orbits around our galaxy, the Milky Way, located in one of its arms.<\/p>\n\n\n\n

\n

The Solar System was formed approximately 4.6 billion years ago, through a long series of processes that currently has the planets revolving around our Sun. <\/p>\n\n\n\n

The evolution that the Sun and the planets must have undergone dates back to a primordial gas cloud composed of 75% of hydrogen and 25% of helium, which accumulated and condensed by the action of gravity, forming large amounts of mass with defined centers.<\/p>\n<\/div>

\"\"<\/figure><\/div>\n\n\n\n

The Sun managed to accumulate enough energy to start nuclear fusion reactions, which make it shine and remain stable. The planets, on the other hand, were formed by the accumulation of material (rocky or gaseous), by the action of gravity, in a process called accretion<\/em>, managing to become the planets we know today, while others did not achieve such evolution and remained as the asteroids we know today, most of them located in the main belt between Mars and Jupiter.<\/p>\n\n\n\n

\n

The Solar System has numerous celestial bodies that orbit its central star, the Sun. <\/p>\n\n\n\n

Among these, the planets are perhaps the most recognized: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus<\/strong> and Neptune<\/strong>. <\/p>\n\n\n\n

Earth is, naturally, the planet we know best, since it is our home and the only one currently known to allow the presence of life today, thanks to various internal and external conditions that help its habitability.<\/p>\n<\/div>

\"\"<\/figure><\/div>\n\n\n\n

Planets have properties that make them unique, although we can identify 2 very different classes:<\/p>\n\n\n\n

inner planets<\/strong>: They are also called telluric or terrestrial; They correspond to the four planets closest to the Sun: Mercury, Venus, Earth and Mars<\/em>. They are characterized by being small, high-density planets, formed mainly by rocky and metallic materials. The natural boundary between the inner and outer planets is the asteroid belt between Mars and Jupiter.<\/p>\n\n\n\n

Outer planets<\/strong>: Also called giants or gas giants, they are those located beyond the asteroid belt: Jupiter, Saturn, Uranus and Neptune. Gaseous planets lack a solid surface. They are characterized by being huge and having low density, rotating very quickly, having ring systems and several satellites.<\/p>\n\n\n\n\n\n\n\n

The concept of "planet" did not have a formal definition for a long time. It was only in August 2006, in a resolution adopted by the U.S.International Astronomical nion<\/em>, it was decided to agree that a planet is a celestial body that meets 3 requirements:<\/p>\n\n\n\n

1)<\/strong>\u00a0It orbits around a star or remnant of it.
2)\u00a0<\/strong>It has enough mass for its gravity to overcome rigid body forces and reach hydrostatic (nearly spherical) equilibrium.
3)<\/strong>\u00a0It has "cleaned" the vicinity of its orbit of planetesimal objects (dominance).<\/p>\n\n\n\n

Training and evolution<\/strong><\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

Initially, there was a gaseous cloud or "nebula" composed of hydrogen, helium and dust floating in space. Due to gravitational and centrifugal action, this nebula contracted, condensed and slowly formed a hot core around which the outer part of this nebula rotated, in an accretion disk. <\/p>\n\n\n\n

Over time, as the core contracted more, the temperature increased and around it remained traces of dust and material that gathered together, thus forming the planets.<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

After a while, the core of this gaseous cloud has begun the first thermonuclear reactions, through the fusion of hydrogen into helium, beginning to emerge a new bright star, our Sun, while around it the planets of this system finished forming and consolidating. ; Meanwhile, many other solid bodies that did not manage to form planets consolidated as asteroids, comets, dwarf planets or smaller bodies. <\/p>\n\n\n\n

Thus, once the Sun and the planets began to establish themselves, our Solar System had finally formed.<\/p>\n\n\n\n

Solar system in balance<\/strong><\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

Our Sun is currently in balance. Nuclear fusion reactions, where 4 hydrogen atoms combine to form 1 helium atom, are constant and undisturbed. <\/p>\n\n\n\n

Every second, 700 million tons of hydrogen are transformed into helium, and the radiated energy is stable, without affecting the planets around it; The planets are already consolidated and the frequent impacts of asteroids ceased a long time ago, whose craters are now only a memory, although the possibility of a considerable impact occurring again on a planet (including Earth) exists.<\/p>\n\n\n\n

The Solar System moves slowly around our galaxy, the Milky Way, over a period of 225 million years. Currently the Sun is in its maturity stage; It has already lived for 5,000 million years and still has another 5,000 million years left.<\/p>","protected":false},"excerpt":{"rendered":"
