Here's what you need to know:
* Average distance: Earth's average distance from the Sun is approximately 93 million miles (150 million kilometers). This is often referred to as an astronomical unit (AU).
* Perihelion: The closest point in Earth's orbit to the Sun is called perihelion. This occurs around January 3rd, and the distance is about 91.4 million miles (147.1 million km).
* Aphelion: The farthest point in Earth's orbit from the Sun is called aphelion. This occurs around July 4th, and the distance is about 94.5 million miles (152.1 million km).
So, depending on where Earth is in its orbit, the distance from the Sun varies slightly.
