The Earth moves around the Sun.
It takes 365.25 days (one year) to go all the way around.
The Earth is said to be orbiting the Sun.
As the Earth moves around the Sun it is also spinning.
It takes 24 hours (one Day) to spin around on its axis - the axis is an imaginary line through the middle of the Earth from the North pole to the South pole.
