LYRICS :
We live in a solar system
In the centre is the Sun
All the planets move around it
We’ve seen every single one
Orbiting the big, bright sun
Orbiting the big, bright sun
Planets in our solar system
1,2,3,4,5,6,7,8
Telescopes, they help us see them
We’ve seen every single one
Orbiting the big, bright sun
Orbiting the big, bright sun
Mercury, Venus and Earth and Mars
And Jupiter and Saturn. Uranus too, and don’t forget that pretty blue Neptune.
We live in a solar system
In the centre is the Sun
All the planets move around it
We’ve seen every single one
Orbiting the big, bright sun
Orbiting the big, bright sun
