The new system found popularity among astronomers, and since then, the final designation of a minor planet is a number indicating its order of discovery followed by a name. Even after the adoption of this system, though, several more minor planets received symbols, including 28 Bellona the whip and lance of Mars' martial sister, 35 Leukothea an ancient lighthouse and 37 Fides a Latin cross (). According to Webster's "A Dictionary of the English Language", four more minor planets were also given symbols: 16 Psyche, 17 Thetis, 26 Proserpina, and 29 Amphitrite. However, there is no evidence that these symbols were ever used outside of their initial publication in the "Astronomische Nachrichten".
