The solar system

We are nine sisters
Calling us planets
Mercury, Venus, earth
And Mars are the inner planets
Jupiter, Saturn, Uranus
And Neptune are the outer planets
Pluto is dwarf planet
Every one of us has its path
Around our friend sun
Which gives us the light
The heat and also the rays
When on of us
Take complete path
Around the sun it called a year
When she turned around herself
It called a day
The earth turned in a path
Around the sun
It called a year
And the four seasons appear
The winter and the spring are there
The summer and the autumn appear
To complete the seasons of the year
