Edmond Halley ‘s comet shot by when he was 2 years old, in 1658. He arrived at many interesting conclusions about it (later), most of which confuse Us Rhinos. He said it would show up about every 75 years.
That said, this same comet was dropping by long before Mr. Halley tagged it. One such visitation was on April 19, 607 AD.
Impressive then too, just the same as if We understood it better. Pretty.
