It comes from the asteroid belt between Mars and Jupiter, and its age is estimated to be over 4.5 billion years. This belt contains many asteroids and meteorites that sometimes break off and travel through space until they eventually impact Earth. Muonionalusta is a fragment of one of these asteroids that survived atmospheric entry and hit the Earth's surface.\nDiscovery and classification\nThe first fragment of this meteorite was discovered in 1906, with more found throughout the 20th and 21st centuries, some weighing several hundred kilograms. It is classified as a fine octahedrite of type IVA and is particularly known for its remarkable Widmanstätten patterns, which are irregular crystal structures of iron-nickel. These patterns are formed through the slow cooling of the metal in space. Not all iron meteorites exhibit these patterns. To reveal them, the surface must be polished and etched with dilute nitric acid, preferably mixed with methanol.\nComposition\nThe Muonionalusta is composed of approximately 91% iron, 8.4% nickel, small amounts of rare elements such as gallium, germanium, and iridium, and various minerals.\u003c\/p\u003e","brand":"PeltramMinerals","offers":[{"title":"Default Title","offer_id":58027882021189,"sku":"MEMO97","price":88.13,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0881\/1659\/2965\/files\/61406_photoroom-026-20251027-162358.jpg?v=1779378110","url":"https:\/\/moldavite.it\/en\/products\/meteorite-muonionalusta-38g-extra-quality-norrbotten-sweden-memo97","provider":"Moldavite.it","version":"1.0","type":"link"}
