The average distance from the Sun to the Earth is about 93 million miles (150 million kilometers). This distance is known as an astronomical unit (AU).

The distance to the Sun varies throughout the year because Earth's orbit is an ellipse, not a perfect circle. However, we can talk about the following:

• Average distance (Astronomical Unit): The average distance from the Earth to the Sun is about 149.6 million kilometers (93 million miles). This is also defined as one astronomical unit (AU).

• Perihelion (closest point): Earth is closest to the Sun in early January, at a distance of around 147.1 million kilometers (91.4 million miles).

• Aphelion (farthest point): Earth is farthest from the Sun in early July, at a distance of around 152.1 million kilometers (94.5 million miles).

So, to give a simple answer, the Sun is about 150 million kilometers or 93 million miles away.
