7234 is an open star cluster lying approximately 9200 light years
away in the constellation of Cepheus. It was discovered by William
Herschel in 1787. However, his sister made an error in recorded
the coordinates, which referred to an empty region of the sky. John
Herschel, William's son, discovered the error in 1829 and gave it
the designation of NGC 7235. This makes the cluster unique in that
it actually has two designations.
