Asatru is more Norse based whereas Wicca involves the Celtic religion more-it seems more focused on nature and Asatru seems to focus more on the Norse religion.

Asatru has a specific ethnic focus (Norse) however most of the European traditions (Celtic, Anglo-Saxon, Germanic, etc) have many similarities, as they all sprung from common ground so to speak.

Wicca is a bit different, it is a modern tradition that borrows from many ethnic traditions.

This is an article about the differences and similarities of Wicca and Heathenry/Asatru.

I have not had a chance to read it myself, but I've only heard good things about it, and from people I trust.
