715 Transvaalia (A911 HH)          Discovered 1911-Apr-22 by Wood, H. E. at Johannesburg (UO)
The original planet 715 Transvaalia, discovered 1911 Apr. 22 by H. E. Wood, was recovered on 1920 Apr. 23 as 1920 GZ and given the designation 933 Susi. The identity was discovered in 1928 and the older designation 715 Transvaalia was retained. In the same year the designation 933 Susi was assigned to a newly-discovered planet.
Note: "planet" implies "minor planet"
