Victoria (
speckle interferometry observations show that the shape of Victoria is elongated, and it is suspected to be a binary asteroid, with a moon of irregular shape.[6]
This minor planet was discovered by English astronomer
Astronomical Journal, adopted the alternate name Clio (now used by 84 Klio), proposed by the discoverer. However, W. C. Bond, of the Harvard College Observatory, then the highest authority on astronomy in America, held that the mythological condition was fulfilled and the name therefore acceptable, and his opinion eventually prevailed.[7]
The historical symbol for Victoria was a star with a branch of laurel. It is in the pipeline for Unicode 17.0 as U+1CEC5 ().[8][9]
