Asteroid 471926, Jormungandr, was discovered on May 28, 2013 by Jost Jahn at Observatoire de Haute Provence in Saint-Michel-l'Observatoire, Alpes-de-Haute-Provence, France. It has a period of 1 year, 283 days.
It was named for Jormungandr, a sea serpent in Norse mythology. The serpent was so large that it surrounded the earth and grasped its own tail; when it moved in the ocean, it caused huge storm surges.
Asteroid Jormungandr seems to mean "too heavy to lift", creating storms or trouble, enormity, possibly global scale.
