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

Here are some average distances:

* Average distance: 149.6 million kilometers (93 million miles)

* Perihelion (closest): 147.1 million kilometers (91.4 million miles)

* Aphelion (farthest): 152.1 million kilometers (94.5 million miles)

So, depending on where Earth is in its orbit, the distance to the Sun can vary by a few million kilometers.
