Astronomy.

Astronomy is a science about space. It studies different objects in the universe. Our Solar System, planets, stars, comets, satellites, and galazxies are studied by astronomy. Other sciences, such as: chemistry, physics, and mathematics are important for it.

Since ancient times people were interested in the sky and stars. Astronomy was studied in Ancient Greece, Egypt, and Babylon. Epoch changed and science changed, too.

Nicolasus Copernicus, Giordano Bruno, and Galileo Galilei did a lot of important things for astronomy. This difficult science started developing.

Now, scientists use telescopes for space study. New galaxies and planets are being studied nowadays. The universe is very large in it there are many different stars and planets.

Our planet is Earth. It's the third planet from the Sun. The planet situated in the Solar System. The Sun is a star. The Moon is a satellite of the Earth. Also, in the Solar System there are other planets and asteroid belt. Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune are planets. They are different but revolve around the Sun.

The Milky Way is a galaxy where the Solar System locate. It can be notice during a bright night.
