# What is the diameter of the earth's orbit around the sun in miles?

Jan 16, 2016

Semi-Major axis = 93 million miles

#### Explanation:

The Orbit of Earth around the Sun is an ellipse, so the average distance between the Earth is given by the Semi-Major axis of the ellipse.

The Semi-Major axis of the Earth's Orbit is about 1.49 x ${10}^{8}$ km

1 mile = 1.6 km

1 km = 1/ 1.6 = 0.625 miles

1.49 x ${10}^{8}$ km = 9.312 x ${10}^{7}$ miles

OR

Semi-Major axis = 93 million miles
