The Solar System is a system consisting of a Sun and its interplanetary system. By approx. The Solar System is about 4.6 billion years old. The mass of the Solar System is approx. 1.0014 M☉. Besides the fact that our Solar System has the Sun in the middle and the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, the Solar System also includes the 5 dwarf planets: Ceres (which can also be considered a larger asteroid, but it is a dwarf planet), Haumea, Makemake, Pluto, Eris. It also includes the asteroid belt between Mars and Jupiter, and it contains the dwarf planet Ceres, the Kuiper Belt, which is after Neptune and includes Haumea, Makemake, Eris and Pluto (almost). Many researchers talk about the existence of a ninth planet in the Solar System. Don't think it's Pluto, no, the ninth planet is farther from Neptune. Planet with no. 9 is said to be somewhere at 200 AU from the sun, which would mean at the very edge of the Solar System. Most planets in the Solar System are made of metal and rocks. Of these 8 planets, 2 are gas giants, meaning Jupiter and Saturn. Other two planets are ice giants, namely Uranus and Neptune. The other 4 are terrestrial or inner planets: Mercury, Venus, Mars, Earth. As far as we know, our Solar System is not in the middle of the Milky Way galaxy. Our solar system is somewhere 26,000 light-years from the center of the Milky Way galaxy located in the Orion arm. We remind you that the Milky Way is 100,000 light years away, so our Solar System could be somewhere on the edge. Until the 17th century, it was believed that the Earth's planet was at the center of the Solar System and that the Sun and Moon revolved around the Earth, even the other planets. Galileo Galilee demonstrated in the 17th century that the Earth revolves around the Sun. Nicolaus Copernicus argued the same thing. This explanation has been contradicted by the Church. Their ideas were accepted long after. As you know the distances between the planets or the planet-Sun are extremely large, even those between the natural planet-satellite sometimes. That is why UA (small astronomical unit) was invented, and 1 AU is the Earth-Sun distance. 1 AU is equal to 149 597 871 km. 

The region where the terrestrial planets are located together with the asteroid belt, this region is called: inner Solar System. Inner planets are the four terrestrial planets that are considered so because they contain rocks or other minerals such as silicates, are dense and have only a few months or not at all. Mars has 2 moons, Earth has 1 moon, and Mercury and Venus have none. The planet-Sun distances are: Mercury: 0.4 AU Venus: 0.7 AU Ground: 1 AU Mars: 1.5 AU. Then come Outer planets, also called Jovian planets which is the group of ice giants and gas giants: Jupiter, Saturn, Uranus, Neptune. They are so called because they are made of hydrogen and helium, respectively ice, and all four have rings. Sometimes we only see Saturn's rings because there are more and they are bigger, the others are smaller, but they exist. The planet-Sun distances are: Jupiter: 5.2 AU Saturn: 9.5 AU Uranus: 19.2 AU Neptune: 30.1 AU. Which suggests greater distances between them. The terrestrial planets are closer, but they are far apart. Jupiter and Neptune also contain Centaurs, which are our ice comets orbiting around them. The Solar System also contains comets, asteroids, but in addition to these it also contains the Trans-Neptunian region. Where is Neptune and the Kuiper belt and the dwarf planets: Haumea, Makemake, Eris and Pluto, Ceres had been in the asteroid belt between Mars and Jupiter. The Solar System ends after the Oort Cloud, in the interstellar region, where Voyager 1 and Voyager 2 arrived and transmitted spectacular images. After leaving the Solar System we will see that light will appear somewhere a few years ..., the Alpha Centauri star system, the closest being Centauri A and Centauri B. Later we will meet the star called: AC + 79 3888. After we have passed these stars, other great wonders of the Milky Way follow, perhaps some not yet discovered.
