According to Max Wolf, this object was discovered by him on March 18, 1892 with a temporary designation of 1892 X, but was soon lost before his orbit was calculated. Repeated observation took place only once - on March 20, but after 100 years in 1982, astronomers Richard West , C. Madsen and L. D. Schmadel showed that this observation did not relate to an asteroid, but to one of the stars of the galaxy. Thus, it was proved that the object 1892 X actually never existed. A little later, in the same year of 1982, the name and sequence number of an imaginary asteroid were assigned to another asteroid Max Wolf, discovered by him on February 2, 1910 with the temporary designation A910 CB and earlier by mistake being in the list of asteroids with the order number 783, which now has the asteroid (783) Nora . Because of this error, it was necessary to rearrange the asteroids in places and change the numbering of several hundred asteroids in the list.
