What a fantastic coin!
People interested in
astronomy may find it interesting to look up the comet.
It has the numerical designation "C/-43 K1" but may have disintegrated or left the solar system, as it is not known to be periodic.
It
had an absolute magnitude of -4.0, and modern scholars believe that the same comet was also visible in
China (as a tail) about a month prior to its display of maximum brightness during the festival of
Ludi Victoriae Caesaris. It shone over a period of about a week.
