The phenomena of the stars and the moon have always aroused human curiosity, from the earliest times in history. In Antiquity people did not know how to explain the phenomena so they associated them with the gods.
Until about 500 years ago, some believed that the Earth was flat and flat like a disk. In the 16th century, important conclusions emerged that in reality the Earth is rounded and that it revolves around the sun and around itself, but confirmation of this only came in the second half of the century XX.
The Earth, despite its size, has an address in the Universe. The Universe is very complex, it has several elements. Look:
Meteors, popularly known as "shooting stars", are just a few signs that the Earth is not alone in outer space.
There are celestial bodies that make up the galaxy, such as stars, planets, natural satellites and comets, it is estimated that in the Universe there are more than 100 billion galaxies. The galaxy in which Earth is located is called the Milky Way.
Stars are stars that have their own light, as they radiate a large amount of energy.
The Earth is part of the solar system, this is a large group formed by dozens of stars that revolve around a star, the sun. Are part of the solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto (Now, Sedna is in Pluto's place, as this one had been relegated to the planet category dwarf). The Earth is dated from 4.6 to 5.0 billion years, dates that are more accepted by scientists.
