The Sky in Winter / The Sky in Summer

Neither of these two aspects is ever the same throughout the year but will change continuously due to the varying inclination of the earth.
This clip clearly shows the movement of our planet to illustrate the different paths the sun traces across the sky in summer and in winter.
