- The addition of small amounts of osmium to these metals greatly increases their hardness.
- Scientists speculate that the asteroids would probably be very rich in minerals with a very high melting point, such as iron and nickel or rarer metals like tungsten, osmium, and zirconium.
- With the exception of two of the platinum-group metals, osmium and iridium, they have the highest melting temperatures and lowest vapor pressures of all metals.

Origin

Early 19th century: modern Latin, from Greek osmē 'smell' (from the pungent smell of its tetroxide).
