Here's why it's important to note that it's an average:
* Earth's orbit is elliptical: The Earth's path around the Sun is not a perfect circle, but slightly oval-shaped. This means the distance between the Earth and the Sun varies throughout the year.
* Perihelion and Aphelion:
* Perihelion: The point in Earth's orbit where it's closest to the Sun (around 91.4 million miles). This occurs in early January.
* Aphelion: The point where Earth is farthest from the Sun (around 94.5 million miles). This happens in early July.
So, while 93 million miles is a good approximation, it's important to remember that the actual distance fluctuates slightly.
