The solar system

The solar system has been a point of discussion since ancient times, arousing great curiosity for its characteristics and the celestial bodies that make up the entire universe. Therefore, let us know a little more about this wonderful topic in this article.

It is a system made up of several planets, where there are also a set of celestial bodies and astronomical objects that revolve around the sun, considered the only bright star in the entire solar system where the earth is located.

You can get to see a large set of stars, among which the earth stands out. Being a total of eight stars that make up an ecliptic plane, classified into four nearby planets and four external planets, each with unique and variable characteristics.

According to astronomical and cosmological studies, they highlight that other solar systems may exist throughout the universe, which is why it is considered a milky way that encompasses the universe.

The solar system stands out mainly for the presence of the sun in charge of attracting the different celestial bodies, dust and matter that have different magnetic fields as they rotate around it.

Since ancient times, human beings have been very curious about the different heavenly bodies present in the sky, the stars, the moon and the sun; For this reason, they came to invent instruments such as high-exploration telescopes that allow the different elements of the universe to be visualized.

Furthermore, technologies have been developed to bring spacecraft to and discover some of the celestial bodies, mainly the moon and satellites, which have collaborated with the development of telecommunications throughout the world.

Characteristics of the solar system

The solar system is made up of several components that are classified according to their proximity to the sun, such as: dwarf planets, satellites and minor bodies such as asteroids, comets, centurions and meteorites. Also highlighting the presence of solar wind, radiation and magnetic fields.

Planets of the solar system

The planets are considered as celestial bodies composed of different elements and located at different distances. They are revolving around the sun together with their satellites and asteroids in the same direction.

They are characterized by having a specific mass that keeps it stable in gravity and also prevents any other planet from influencing its orbit and colliding with each other.

The classification of the planets has been centered according to their proximity to the sun, with two main groups being the inner planets because they are in the inner orbit of the sun, which are Mercury, Venus, Earth and Mars.

The second group corresponds to those in the outer orbit of the sun, corresponding to the planets farthest from its orbit such as Jupiter, Saturn, Uranus and Neptune. Next we know the basic description of each of them:


It is the planet that is located closest to the sun and the smallest in the entire solar system. It is composed of approximately 70% iron, which is why it is known as the iron planet, in addition to other components such as helium, calcium, magnesium and oxygen.


It is considered as a planet with a very similar condition to the earth, but it is mainly composed of nickel and iron. In addition, it is surrounded by a large amount of toxic gases that surround the entire planet.

It is considered that in the past it came to possess water and possibly in the future it will have the conditions to generate organic matter.


It is a planet with a high percentage of water, terrestrial ecosystems and its atmosphere is made of oxygen It is considered that over time it was a planet that evolved in physical-chemical conditions that allowed life to develop and exist various species.

Another of its main conditions is that it is surrounded by an ozone layer that protects it from the sun's radiation and continues to allow life on the planet. It has its own satellite known as the moon and is made up of 70% liquid water.


It is popularly known as the red planet for having said color throughout its surface, this is attributed to its composition of iron oxide.

It has satellites known as Phobos and Deimos. It is currently under study due to the presence of frozen water under its surface.


It is considered the largest planet in the solar system; it is characterized by having a gaseous composition mainly of hydrogen and helium, it is even considered that they have liquid hydrogen in their internal condition and a great rocky condition.


It corresponds to a planet with a variety of rings (seven in total), its atmosphere is composed of hydrogen and helium, its temperature exceeds that of the sun and it has a rocky composition with liquid hydrogen.


It is a gaseous planet that is composed mainly of methane gas and, to a lesser extent, hydrogen and helium. It has a very cold atmosphere because its temperature reaches up to -200 degrees Celsius. It also has rings that are not as distinguished as Saturn's.

It stands out that it has a very different inclination due to these rings, which makes its poles take a different position compared to the other planets.


It is the planet that is farthest from the sun, it is also one of the gaseous planets that has the same composition as the previous ones with hydrogen and helium, but also hydrocarbons. Due to this it has a very prominent blue color, it has very low temperatures but it has been proven that its core generates heat in the system.

In ancient decades, it was considered that there were 9 planets in the solar system, placing Pluto last, a small celestial body considered to be the farthest in the entire Solar System

In the middle of the year 2006 and various studies carried out, Pluto ceased to be considered a planet, because its conditions did not comply with a celestial body of the system; considering itself as a moon or an asteroid that left its orbit aligned in the solar system.

As is well known, the solar system has been a highly discussed topic since ancient times, arousing the interest of many symbolic characters focused on the study of the universe.
