* Earth's orbit isn't a perfect circle. It's an ellipse, meaning there's a point where Earth is closest to the Sun (perihelion) and a point where it's furthest (aphelion).
* The distance changes constantly. Earth's orbit takes 365.25 days to complete, and the distance between Earth and the Sun varies throughout this journey.
Here are some helpful numbers:
* Average distance: Earth's average distance from the Sun is about 93 million miles (150 million kilometers). This is often referred to as an Astronomical Unit (AU).
* Perihelion: At perihelion, Earth is about 91.4 million miles (147.1 million kilometers) from the Sun.
* Aphelion: At aphelion, Earth is about 94.5 million miles (152.1 million kilometers) from the Sun.
So, to answer your question simply: Earth's orbit is a path around the Sun with an average distance of 93 million miles (150 million kilometers).
