Rotation 1 – the earth rotates to give us day and night
Rotation 2 – the earth rotates around our sun
The Tilt
The tilt of the earth is 23% and this give us our seasons
Equator, in the centre, Northern Hemisphere, Southern Hemisphere.
Summer in Australia is winter in the UK
Equinox
Equinox comes from Latin, meaning equal, night and day
That’s because during an equinox, it’s believed that all areas of the Earth’s surface experience an equal amount of daylight and darkness — 12 hours each.
Happens twice a year. Autumn, the equinox (Sept. 21) is in the northern hemisphere, and in spring, the equinox (Mar. 20 or Mar. 21 — it varies from year to year) is in the southern hemisphere.
So, the equinoxes are the times of the year where the part of the Earth closest to the sun is the exact equator. So when everything is aligned, everywhere from the North Pole to the South Pole will get the same amount of sunlight — but only on those two, equinoxes, in September and March

Our sun is not static
It’s always good to learn and yesterday was no exception for me: From Kym and Levon, I leaned that while I thought the sun was a static object in our solar system, it is far from it, nothing of course is static. ‘Everything in the known universe rotates on an axis and orbits something else in space. The Sun is no exception. We mainly talk about everything in the solar system orbiting the Sun and celestial objects outside the solar system being in relation to the Sun. The answer to the question is : Yes. The Sun and the entire solar system orbits around the center of the Milky Way galaxy. The average velocity of the solar system is 828,000 km/hr. At that rate it will take about 230 million years to make one complete orbit around the galaxy.’ (Universetoday)
