What is Lilii Borea

Lilii Borea is one of the few stars carrying a traditional name in Renaissance Latin rather than Arabic: «the Northern Lily», christened in the seventeenth century by the celestial atlas of the astronomer Augustin Royer, who drew there a constellation called Lilium in honour of the King of France. The constellation fell out of use; the name survived. An orange K-class giant in Aries, about 172 light-years away.
