What does mercury and earth have in common?

Answer 1

Mercury, in common with the Earth, has it's own (weak) magnetic field. It is the closest planet to the sun, and has no atmosphere whatsoever. It is the smallest planet in the solar system, and yet it's density is very similar to Earth's (another thing in common). Since they are both planets it could be argued that they have that in common, too.

Answer 2

They are both planets and in that respect, they are:

• massive enough so that they are approximately spherical as a result of their own gravity,
• not so massive as to generate thermonuclear fusion, and
• have cleared their neighbourhood of planetesimals.

Answer 3

Mercury and Earth are both terrestrial planets in our solar system, meaning they are composed predominantly of rock and metal. They both have a layer of iron in their cores, although Earth's core is much larger compared to its size. Additionally, both planets have a thin atmosphere, with Earth's being much denser and supporting life.

Answer 4

Both are solid, have iron and orbit the Sun.
