The (orbit) Ceti Alpha V settled into would be different from Ceti Alpha VI's original one.
assuming you left out the word "orbit" I answer this with the following:
"Captain, we have entered the system. There is a problem with the fifth and sixth planets. Our scans do not match what is recorded on our charts."
"Short-range sensor scan."
"Captain, it would appear that Ceti Alpha V has undergone a violently explosive breakup. The resulting gravitational disturbances appear to have affected the orbit of Ceti Alpha VI."
"Well, we aren't here to map planetary orbits. Preliminary scan of Ceti Alpha VI?"
"Sensors record no obvious signs of life. Still too far out for conclusive readings."
"Very well. Helm, standard orbit around Ceti Alpha VI."
"Aye sir..."
