By how much does the earth-Sun distance change? 300,000 miles 500,000 miles 3,000,000 miles 3,500 miles

3,000,000 miles

Explanation:

The Earth's perihelion distance is about 147,000,000 kilometers and its aphelion distance is about 152,000,000 kilometers. So, the change in distance is about 5,000,000 kilometers which translates to about 3,000,000 in Miles.
