INTRODUCTION
Technological developments have allowed us to obtain unprecedented knowledge about our Solar System.
The Solar System –ourselves included- is continuously travelling around the galaxy.
THE ORIGINS OF THE SOLAR SYSTEM
Our Solar System started to form itself some 5,000 million years ago.
Theory on the origins of the Solar System.
The planets closest to the Sun are: Mercury, Venus, the Earth and Mars.
The outermost are: Pluto, Jupiter, Uranus and Neptune.
THE SOLAR SYSTEM
The Sun’s mass is 743 times more than all the other objects in the Solar System combined.
Mercury: its localisation and main characteristics.
Venus: its localisation and main characteristics.
The Earth: its localisation and main characteristics.
Mars: its localisation and main characteristics.
The asteroid “Hermes” located between Mars and Jupiter.
Jupiter: its localisation and main characteristics.
Uranus: its localisation and main characteristics.
Neptune: its localisation and main characteristics.
Pluto: its localisation and main characteristics. Its satellite Caronte.
Meteorites.
Comets.
THE FUTURE OF THE SOLAR SYSTEM
In 5 million year’s time, the Sun will increase in size and convert itself into a giant red ball which will engulf the Earth.
Stars making up those other galaxies will probably also have planets revolving around them.
In the interior of the “Voyager” space-probe there is a message from the planet Earth.
