Mercury is a rocky planet.It's actually a rock because it is one of the inner planets that are all made of rock.The planet Mercury is a dense, rocky, airless world.
Mercury's mantle is mostly made up of silicate minerals, similar to Earth's mantle. This layer is believed to be composed of magnesium silicates like olivine and pyroxene.
Jupiter is the planet mostly made of gases. It is a gas giant, primarily composed of hydrogen and helium, with no solid surface like terrestrial planets. In contrast, Mercury, Mars, and Venus are rocky planets with solid surfaces.
The inner or terrestrial planets are mostly rock (sliicates) and metals; Mercury is no exception. It is thought to have a relatively large iron core.
Mercury is predominantly composed of metal and rock, with a small iron core. It does not have a significant atmosphere, so it is not mostly gas like the gas giants in our solar system.
Mercury is a rocky planet.
no
No. The element mercury contains only mercury atoms. The planet Mercury is made mostly of silicon, oxygen, and iron.
Oddly, Mercury is actually mostly metal. Mercury has a thin rocky crust and a very large iron core.

Yes it is
I believe it is IRON.
your mommas smelly dick

== == Mercury has an iron-nickel core.
how am i supose to now im yhe one asking the question
Mercury has a surface pressure that is near enough zero (or a vacuum), the planet holds no real atmosphere due to its small size. There are some trace gases at the surface, but not what one would call a proper atmosphere.
