Why the name 23 Degrees

The earth is tilted at an angle of just over 23° – When a Mars-size object collided with Earth around 4.5 billion years ago, it knocked off a chunk that would become the moon. It also tilted the Earth meaning that our planet now orbits the sun at an angle of 23°, giving rise to the different seasons.
