Medieval astronomical records, such as the Bayeux Tapestry, could help narrow down the location (or at least infer the existence) of the hypothetical Planet Nine:
Scientists suspect the existence of Planet Nine because it would explain some of the gravitational forces at play in the Kuiper Belt, a stretch of icy bodies beyond Neptune. But no one has been able to detect the planet yet, though astronomers are scanning the skies for it with tools such as the Subaru Telescope on Hawaii's Mauna Kea volcano.
Medieval records could provide another tool, said Pedro Lacerda, a Queen's University astronomer and the other leader of the project.
"We can take the orbits of comets currently known and use a computer to calculate the times when those comets would be visible in the skies during the Middle Ages," Lacerda told Live Science. "The precise times depend on whether our computer simulations include Planet Nine. So, in simple terms, we can use the medieval comet sightings to check which computer simulations work best: the ones that include Planet Nine or the ones that do not."

The stupid Live science article states that 1066 was in the Dark Ages, which is wrong. It was firmly in the Middle Ages, and in fact Dark Ages is not a thing. It is now known as the Early Middle Ages.
Sorry, this annoyed me more than it should perhaps and I had to get it off my chest.
Carry on now.

I was there! Pretty frigging dark! More darkness than light! People becoming illiterate, travel was very dangerous, roving bands of deplorables (we called them "Germanic Barbarians"), and Twitter was the dominate mode of communication. There was an idiot king, and a mad man for a pope, but fortunately the Idiot King fired the pope, and he had to go back to Brietbart, so things were not as bad as they could have been. Kinda like now, actually.

Well, only about 100 or so years later, there was a mongol who got annoyed by that darkness and started to lit villages and cities - as in "setting them alight".
Needless to say, after a while it was even darker and somehow colder.
