Space facts.

The word star comes from the Ancient Greek word ‘aster’ which means ‘a star’.

There are at least a billion trillion stars in the universe.  That’s more than all the grains of sand on all the beaches on earth.  In our Milky Way galaxy there are roughly 200-400 billion stars.

It is estimated, the stars that you see out of your window are around 1 and 10 billion years old.

Stars have a variety of colours determined by their temperature.  Such as, brown, red, orange, yellow, white or even blue.  The hotter it is the brighter it is.

Groups of stars are called constellations.  There are 88 different constellations recognised in our sky. Such as:




Canis Major;

Cygnus (known for the northern cross.);


Scorpius and Leo.

Earth has two forms of energy, heat and light; obviously from the nearest star to earth namely, the Sun itself!
