The distance of Earth's annual circuit around the Sun is not a single number, as Earth's orbit is not perfectly circular, but slightly elliptical.

Here's how we describe the distance:

* Average distance: 149.6 million kilometers (93 million miles). This is also known as 1 Astronomical Unit (AU).

* Perihelion (closest to the Sun): 147.1 million kilometers (91.4 million miles)

* Aphelion (farthest from the Sun): 152.1 million kilometers (94.5 million miles)

So, the distance Earth travels in its orbit varies throughout the year, but the average distance is about 149.6 million kilometers.
