Mercury is a high density planet. It has the second highest density of all the planets in the solar system.
Mercury
The planet with the lowest overall density is Saturn.
Mercury is the closest planet to the sun. It has many craters, ridges, and harsh terrains. It is the smallest planet in the solar system.
That might be an indication that Mercury has a similar composition to Earth. For more details, check the Wikipedia articles on Earth, and Mercury, to see what is believed to be inside each planet.
After Earth, Mercury is he densest body in the solar system. This high density is due to the fact that the majority of Mercury's interior is probably composed of a large, iron core.
Venus, Earth and possibly Mars. Mercury's density is too low for Mercury to have a dense core.

5.43 g/cm3
Mercury has the second lowest density of any planet in the solar system. Saturn has the lowest density of any other planet.
The planet with the lowest overall density is Saturn.
1. The chemical element has a density of 15,534 g/cm3 at 20 0C. 2. The planet Mercury has a density of 5,427 g/cm3.
The planet with the least mass and smallest is Mercury. The planet with the lowest density is Saturn
mars
Saturn has a very low density overall, on average it is 0.7 g/cm3, less than the density of water. It is the least dense planet in our solar system.
Mercury. Whilst it is not the most dense (Earth being the most dense planet of the Solar System), without gravitation compression on the Earth, Mercury would be the most dense. So if Earth was the same size as Mercury, Mercury would be the densest planet. It is also the smallest planet.
They both have an iron core, and they have the same density.
Mercury. Although it has a high density, it's the smallest planet and least massive overall.
