How imprecise, Twilight! I do believe you mean one thousand three years ago.



. . . You know, it's kind of a suspicious coincidence that they get this shower once every 334 years. The comet can't be leaving a long dust trail, or there'd be biannual showers for several years every 334 years, but in that case it needs to be on an orbit that actually is 334 years, not just approximately 334 years. Otherwise they wouldn't consistently hit the dust. It's not exactly normal to see 334:1 orbital resonance.
