Winter

: The reason we have winter is because the north hemishpere is pointed away from the sun.
: the axis is pointed to the north star and during the perihelion the North Star is away from the sun so the axis is pointed away from the sun that is why it is winter.
: during the winter people think the earth is farthest away but actually it is the closest to the sun.
: during the winter we have indirect sunlight have a low solar angle which causes shorter days.
