458 Hercynia, provisional designation 1900 FK, is a background asteroid from the outer regions of the asteroid belt, approximately 38 kilometers in diameter. It was discovered on 21 September 1900, by astronomers Max Wolf and Arnold Schwassmann at the Heidelberg-Königstuhl State Observatory in southwest Germany.[19] The asteroid was named for the ancient Hercynian Forest, known to the Romans as "Hercynia silva".[4]
