The north star
Because Earths axis is tilted.
we have seasons because of how the earth is tilted on the earths axis, for example if you live in england, its winter when your futher away from the sun and you have summer when your tilted towards the sun.
depends on which hemisphere you live if on top it is towards the sun
There would be no four seasons if the earths axis was not tilted.

without the tilted axis the whole planet would be impossible to live on since this angle is a state of equilibrium
