What is the planet Mercury made from?

Answer 1

Mercury was formed as with all planets in our solar system by accretion.

As the proto planets orbited the Sun, asteroids and other stellar stuff were attracted by the now growing mass of Mercury, adding to it's mass and thus it's gravity. It drew more and more interstellar material until there was little left to absorb.

However, another proto planet about the same size as Mercury was in the same orbit as Mercury and they collided. This "merger" ejected the lighter elements out into the Solar System, whilst the heavier elements combined, giving Mercury is current massive iron core.

Answer 2

The planet Mercury is mainly made from a rocky surface and metallic core. This accounts for about 75% of the planet.

Answer 3

Mercury is an element, therefore it's made of mercury. On the Periodic Table it's "Hg".

Answer 4

Mercury is an element it is thus made of Mercury

Answer 5

Mercury is an element, meaning that it isn't "made out of" anything but mercury. For more information, check out a periodic table of the elements, Mercury is number 80 (its symbol is Hg).

Answer 6

Mercury, at sea level pressure and room temperature, density is low enough to be a liquid but too dense to be a gas. Liquid is its natural state.

Answer 7

Mercury is mostly iron in composition.
