Question 10. How far away is the Sun?

The average distance from the Sun to the Earth is 93 million miles (149 million kilometers). Because the Earth’s orbit around the Sun is not a perfect circle, it varies. At its closest point to the Sun, known as perihelion, the distance is 91 million miles (146 million km). At is farthest point, known as aphelion, the distance is 94.5 million miles (152 million km).
