It's not quite that simple! There's no single answer to how many million miles it is to orbit the sun. Here's why:

* Earth's orbit is elliptical: It's not a perfect circle, so the distance between Earth and the sun varies throughout the year.

* Different planets have different orbits: Each planet in our solar system has its own orbital path, meaning each has a different distance from the sun.

What we can say:

* Earth's average distance: Earth is about 93 million miles (150 million kilometers) from the sun on average.

* Closest and farthest points: At its closest point (perihelion), Earth is about 91.4 million miles from the sun. At its farthest point (aphelion), it's about 94.5 million miles away.
