Two long-duration probes are placed in star-centered orbits. Probe R has semimajor axis 10 million km, and Probe S has semimajor axis 40 million km. Which calculation correctly compares P_Probe S to P_Probe R?
A
P_Probe S/P_Probe R = (40/10)
2
= 16
B
P_Probe S/P_Probe R = sqrt(40/10) = 2
C
P_Probe S/P_Probe R = sqrt((40/10)
3
) = 8
D
P_Probe S/P_Probe R = 40/10 = 4
