10. Earth's axial tilt

Not only does the Earth revolve around the Sun every year, but the Earth rotates on its axis every 24 hours. This is what we call a day.

However, the Earth doesn't rotate in a straight up and down manner relative to the Sun. It is slightly tilted from its orbital plane with the Sun.

The orientation of Earth’s tilt with respect to the sun – our source of light and warmth – does change as we orbit the sun.

The tilt has two major effects: the angle of the Sun to the earth and length of the days.

 For half of the year the Earth is tilted such that the North Pole is more pointed towards the Sun.

 For the other half the South Pole is pointed at the Sun.

The video shows planets and dwarf planets to scale in size, rotation speed & axial tilt in distance order from Sun.
