Caesar's Comet
Caesar's Comet (also Sidus Iulium ("Julian Star"); Caesaris astrum ("Star of Caesar"); Comet Caesar; the Great Comet of 44 BC; numerical designation C/−43 K1) was a seven-day cometary outburst seen in July 44 BC. It was interpreted by Julius Caesar's contemporaries in Ancient Rome as a sign of the deification of the recently assassinated dictator (100–44 BC). Based on two questionable reports, one from China (May 30) and another from Rome (July 23), an infinite number of orbit determinations can fit the observations, but a retrograde orbit is inferred based on available notes.
