    • THE SOLAR SYSTEM Science 2
    • Our Solar system  We live on the surface of the Earth. The Earth is one of eight planets that orbit around a big star we call the Sun.
    • The Planets
    • The Planets A planet is a celestial body orbiting a star. The names of the eight planets in our Solar System are:  Mercury  Venus  Earth  Mars  Jupiter  Saturn  Uranus  Neptune
    • Orbits  Orbits are the circular movements the planets describe around the sun. The closer the planet is to the sun, the faster it moves.  The Earth takes exactly one year to describe an orbit around the sun.  The rest of the planets spend more or less time to travel round the sun.  They are named after Roman gods.
    • Mercury  It is the closest planet to the sun.  It is made of rock  It is very small  It travels faster than all the others, so it was named after the messenger god.  Planets
    • Venus  It is the second planet from the sun.  It’s very hot and it’s got a toxic atmosphere  It’s the same size as the Earth  You can see it at dawn and it looks so beautiful that was named after the godess of beauty  Planets
    • Earth  It is our planet, the only we know having living things.  It is covered by water, land and air.  The temperature is mild  It has a satellite called the Moon  Planets
    • Mars  It is made of rock, frozen ground and iron  It is half the size of Earth  Scientist believe there is ice (water) on the poles.  It is red, so it was named after the god of war.  Planets
    • Jupiter  It is the biggest planet in our Solar System  It is made of gases, and there are huge storms on its surface  It has more than 16 moons around it.  As it is the biggest one, it was named after the king of gods  Planets
    • Saturn  It is made of gas, and its beautiful rings are made of ice and rocks  It has more than 30 satellites  As it is so far from the Sun, it takes a lot of time to orbit, so it was named after the god of time  Planets
    • Uranus  It is another of the four cold giant gas planets  It is made of frozen gas and ice  It is blue, so it was named after the god of the sky  Planets
    • Neptune  It is the eighth planet from the sun.  It is very big, made of light gases  It has eight satellites  It has a color similar to the ocean, so it was named after the god of the seas.  Planets
    • Pluto  It is not considered to be a planet anymore, as it hasn’t got a normal orbit  It is very small and cold and it is made of rock  As it is so very far from the sun, it was named after the god of death  Planets
    • The Sun  The Sun is our star. All planets in our solar system orbit around it, including the Earth.  The Sun is an enormous mass of very hot gases (Helium and Hydrogen) in continuous explosion  These nuclear explosions give light and heath to the Earth, so that life can be possible.  Never look direclty at the Sun or it might blind you!

    • GLOSSARY Celestial body: Any astronomical object existing in outter space. Orbit: Circular movement almost all the celestial bodies describe around a bigger one Planet: Celestial body which orbits around a star Satellite: Celestial body which orbits around a planet. The Moon is the Earth’s satellite.
