Solar System

We have eight planets in our Solar System.

their names are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

The biggest is Jupiter and the smallest is Mercury.

Pluto was considerated a planet in the Solar System, however, researches by the International Astronomical Union (IAU) defined three fundamental concepts for the classification of planets: - - Orbiting around a star;

- Have its own gravity;

- Having a free orbit.

Thus pluto was considered a dwarf planet because it does not have a free orbit. Mercury is closest to the sun and fastest, made up basically of iron, it can be seen from Earth with the naked eye.

Venus it is the second planet closest, besides the Sun and the Moon is the brightest celestial body in the sky.

Earth it has liquid water and oxygen in its atmosphere, which makes life on the planet possible.

Mars it is the second smallest planet of the solar system, known as the red planet because of the color of its surface.

Jupiter is the largest planet in the solar system, consisting mainly of the gases hydrogen, helium and methane, plus a small solid core inside.

Saturn is the second largest planet in the solar system, known for its rings made of ice and cosmic dust.

Uranus the third largest planet in the Solar System and the seventh planet from the sun, Uranus is a gaseous planet that averages a temperature of -185°C and has 27 satellites.

Neptune has 14 natural satellites and has average temperatures of about -200°C.

And located at the center of the Solar System, the Sun is responsible for the gravitational interaction of the 8 planets and other celestial bodies around it. Its mass represents 99.8% of the entire mass of the Solar System.
