Question

Explorer 35's orbit measured 11,400 kilometers across its long dimension. What was the orbit's semimajor axis in kilometers?a. 5,700 kmb. 9,600 kmc. 11,400 kmd. 22,800 km

Answer 1

option (a)

Explanation:

Length of long dimension = 11400 km

It means it is the length of major axis.

So, the length of semi major axis = 11400 / 2 = 5700 km

Thus, the length of semi major axis is 5700 km.
