Space probes communicate with controllers on Earth using radio waves. Suppose a probe has a radiotransmitter that operates at a frequency of 813.0 MHz when at rest relative to the observer. This probe is now wandering the solar system. The signal you pick up from the probe is shifted 9.356E+4 Hz lower in frequency than the rest frequency given above. How fast is the probe traveling and is it traveling towards or away from Earth?
