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.
What else can I help you with?
What is the most dense planet?
Mercury has a density of 5.427 g/cm³ Earth has a density of 5.515 g/cm3 So Earth is the most dense planet. [See discussion for more information] NB: Mercury is the most dense planet in our solar system when not accounting for gravitational compression.
What planet would you expect to have a rocky crust and a dense core?
Venus, Earth and possibly Mars. Mercury's density is too low for Mercury to have a dense core.
Which planet is the highly dense planets nearest to the sun?
Terestrial planets Mercury, Venus, Earth and mars.
Is Planet Mercury made mostly of gas or rock?
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.
What is a planet other than earth that is small dense and rocky?
mars, the poles are made of ice, so its dense. its obviously rocky and small.
What planet is most dense Mercury Venus or earth?
Earth, with a density of 5.515 gr/cm3, it is the densest planet in the solar system.
What planet has the same density to earth?
Mercury is only slightly less dense than Earth.
Which planets in our solar system are more dense then earth?
Mercury, Venus, and Mars are more dense than Earth. This means these planets have a greater mass-to-volume ratio, indicating a higher concentration of materials in their composition compared to Earth.
Which planet in our solar system has the greatest density?
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.
What planet has the smallest gravitional force?
Believe it or not Mars has the weakest gravity of the planets.Mars = 0.376gMercury = 0.38gEven though Mercury is the smallest planet, it is very dense.
Is the earth moon less dense than mercury?
Yes, the Earth's moon is less dense than Mercury. Mercury is one of the densest planets in the solar system, with a density about 5.4 times that of water, whereas the Moon has a density about 3.3 times that of water.
Mercury is a ball of what?
Mercury is a terrestrial planet composed mainly of rock and metal. It is a dense, cratered world with a large iron core that makes up a significant portion of its mass.
