Question

Diameter of earth's orbit around sun

Answer 1

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 × 10 (8)km

1 mile = 1.6 km

1 km= 1/1.6 = 0.625 miles

1.49× 10(8) km = 9.312× 10 (7) miles or

semi major axis =93 million miles
