Scientists are making plans to put a probe in orbit around earth. they want the probe to enter the orbit shown below.

which arrow shows the direction that the probe should be moving in order for it to enter the orbit?

w

x

y

z

The answer is X. I just took the quiz on edge. The probe must move in the same direction that the orbit moves in order to enter it. The orbit moves to the left, and X moves to the left, which justifies the answer.
