The distance travelled by light from the planet (or its moon) to Earth is shorter when the Earth is at the point in its orbit that is closest to its planet than when the Earth is at the farthest point in its orbit, the difference in distance being the diameter of the Earth's orbit around the Sun. The observed change in the moon's orbital period ...
There’s also round-trip light time—that’s how long it takes a command to go from Earth to the spacecraft and back. In order to receive data on Earth, you have to command the spacecraft to start sending it 4.5 hours earlier. Likewise, if you want to send something, you have to send it to a point the spacecraft is going to be in 4.5 hours.
