What is the Sun Wheel?
The Sun Wheel is the Earth’s orbit around the Sun which takes 365 and a quarter days.
The Earth’s polar axis is tilted by 23.5 degrees to the plane of its orbit; this is how we get the seasons.
The Northern hemisphere is tilted toward the Sun in June the time of our Summer Solstice and six months later in December and the Winter Solstice, the Southern hemisphere is tilted towards the Sun.
In March and September the Equinoxes, both North and South, have equal amounts of sunlight.
