Mercury is a high density planet. It has the second highest density of all the planets in the solar system.
The planet with the lowest overall density is Saturn.
Mercury has the second greatest density (behind Earth), with a density of 5.43 g/cm3 (5430 kg/m3).
Mercury has a high density because it has a large iron core, making up about 60% of its mass. The iron core contributes to Mercury's high average density, which is close to that of Earth's, despite Mercury being a smaller planet.
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.
Mercury is the smallest planet in our solar system and the closest to the Sun. It has a thin atmosphere and a large temperature variation between its hot days and cold nights. Mercury also has a high metal content, leading to its relatively high density compared to other planets.
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.
Mercury has the second greatest density (behind Earth), with a density of 5.43 g/cm3 (5430 kg/m3).
The density of the planet Mercury is 5.43 gr/cm3 which is equal to 5.43 kg/L
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 has a high density because it has a large iron core, making up about 60% of its mass. The iron core contributes to Mercury's high average density, which is close to that of Earth's, despite Mercury being a smaller planet.
The density of Mercury is 5.4 grams per cc, only a little lower than that of the densest planet - Earth. One of the reasons that the Earth is denser is that its own gravity compresses its material more than it does in the smaller planet, Mercury. If adjustment were made for this gravitational compression, then Mercury would have a density of approx 5.3 g per cc compared to the Earth's 4.4 making Mercury the densest planet.
Why shouldn't it? There isn't a direct relationship between density and size in general.
