The distance from the Earth to the Sun is not constant because Earth's orbit is elliptical.

Here are some ways to describe the distance:

* Average distance: 149.6 million kilometers (149,600,000,000 meters)

* Perihelion (closest point): 147.1 million kilometers

* Aphelion (farthest point): 152.1 million kilometers

So, depending on where Earth is in its orbit, the distance to the Sun can vary by millions of kilometers.
