The solar system is the set formed by the Sun and the eight planets with their respective satellites that rotate around it, they also accompany it in its displacement through the galaxy or the Milky Way dwarf planets, asteroids and innumerable comets, meteorites and interplanetary corpuscles. This system is located about 33,000 light years from the center of the Milky Way.
There are many hypotheses about the origin of the Solar System, the most current theories link its formation with that of the Sun, about 4.7 billion years ago. From an interstellar cloud of gas and dust that fragmented or collapsed, leading to the formation of a primordial solar nebula, and through the union of larger and larger particles the formation of the current planets.
Until August 24, 2006 there were nine planets in the Solar System: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. On that date, the International Astronomical Union created a new kind of planet: the dwarf planets, where Pluto became part of them, along with Ceres and Eris; and later, they have been joined by Haumea and Makemake.
Planets are bodies that move in elliptical orbits around the Sun (translation) and around themselves (rotation). In general, the distance from each planet to the Sun is twice the previous one. The planets, with the exception of Mercury and Venus, have satellites, smaller bodies that rotate around them. The best known satellite is that of the Earth, the Moon.
The planets closest to the Sun are called interior or telluric planets (Mercury, Venus, Earth and Mars), they are small in size, high density, low speed of rotation and have few satellites; the distant planets are known as outer or giant planets (Jupiter, Saturn, Uranus and Neptune), they are large, of low density, fast rotating and have a gaseous consistency and a greater number of satellites.
Jupiter is the largest planet, while Mercury is the smallest, Venus in terms of mass and size has characteristics similar to Earth, and Mars, known as the red planet, is half the mass.
Apart from these main planets and their satellites, there are thousands of small bodies known as asteroids, which are located between the orbits of Mars and Jupiter, in a strip called the asteroid belt . Also we cannot forget comets (balls of ice and dust) and meteorites.
