459 Signe
Signe (minor planet designation: 459 Signe), provisional designation 1900 FM, is a stony asteroid from the background population of the intermediate asteroid belt, approximately 26 kilometers in diameter. It was discovered by German astronomer Max Wolf at Heidelberg-Königstuhl State Observatory on 22 October 1900. The asteroid was presumably named after Signy, a character of the Scandinavian Völsunga saga and Norse mythology. Signy is the daughter of Völsung and sister of Sigmund.
