Iridium
* belongs to a group of metals known as transition metals.
* can store charge by going through valence changes which cause reversible redox reactions.
* chemical element that is very rare on Earth but commonly found in meteorites.
* dense metal, like platinum and gold, which is very scarce in terrestrial rocks.
* forms a variety of complexes of fundamental interest in triplet harvesting.
* hard metal which is rare on earth but common in meteorites.
* hard, brittle, lustrous, dense, transition metal of the platinum family.
* is added to platinum to add even further toughness
  - also available in soluble forms including chlorides, nitrates and acetates
* is an element of the platinum group
  - often found in meteorites and spread on impact
  - which is rare on earth but is common in celestial bodies, such as meteorites
  - expensive metal for which scientists have yet to find an alternative
  - both too expensive to compete in mobile phones and too narrowband for data
  - characterized by a higher melting point than either nickel or platinum
  - chemical elements
  - chemically very unreactive
  - created in the melting of the Earth's crust during a meteorite impact
  - dug out of the Earth's interior during a meteorite impact
  - extremely inert chemically, resisting even the action of aqua regia
* is found in meteorites
  - uncombined in nature as the metal and in combination with osmium and platinum
  - full duplex
  - harder than ruthenium
  - known to be more abundant in meteorites, asteroids, and comets than on earth
  - metallic elements
  - more expensive than ruthenium
* is much more abundant in iron meteorites
  - meteorites than in the Earth's crust
* is one of the least abundant elements in Earth's crust
  - rarest elements in the Earth's crust
  - poisonous for dinosaurs
* is rare in the Earth's crust, but common in comets and asteroids
  - crust of the Earth, but much higher in abundance in meteorites
* is rare on Earth and plentiful in meteorites
  - Earth's surface, but common in solar system objects such as asteroids and comets
* is rare on Earth, but abundant in meteorites
  - relatively common in meteorites or comets
  - though common in meteoritic material
  - earth but common in extra-terrestrial bodies, such as asteroids
* is rare on earth, but is concentrated in meteors and comets
  - more common in space
  - something that starts as a global entity
* is the first global hand-held satellite phone service
  - king of spark plug metals
* is the most corrosion resistant metal
  - corrosion-resistant of all known metals
  - corrosive resistant metal known
  - inert of the precious metals
  - name of a chemical element
  - same type of precious metal as platinum
  - satellite telephone system that was intended to link everyone in the world
  - world's first global telephone and paging company
  - unreactive at room temperatures
* is used in particle physics for the production of antiprotons , a form of antimatter
  - the electrochemical and catalytic applications
  - principally in alloys
* is very rare in earth, but in comets, asteroids, and meteors, it is very common
  - the Earth's crust, but is more common in meteorites and comets
  - white, similar to platinum, but with a slight yellowish cast
* member of the platinum group and is highly resistant to corrosion
* ramp up to full brightness gradually and ramp down.
  * metal. It is very hard to find and costs a lot. Iridium belongs to a group of metals known as transition metals. It looks like platinum and is found in asteroids and comets. It can be used to find out when an asteroid or comet will hit the Earth. It very costly metal that can fold and bend just like aluminum.

  * It can be used to find out when an asteroid or comet will hit the Earth. It very costly metal that can fold and bend just like aluminum. It is very shiny. It is relatively rare on the Earth's crust. Most Iridium is found in Brazil, Canada, Myanmar, Russia, South Africa, and the United States. Iridium is the most corrosion resistant metal.
* rare mineral on earth but was common in comets.
* satellite telephone service devoted primarily to voice operations.
* shows up in meteorites, but it's uncommon on the Earth's surface.
* substance that is rare to earth but commonly found on many meteors.
* takes the distribution of electronic components to the next level.
* very rare chemical.
