Mercury is slightly smaller then the Earths Core. Mercury is believed to have been struck by a planet sized object billions of years ago which blew away everything but the core of the planet.
(If Pluto was still a planet, Pluto would also be smaller than the Earth's core, but it was demoted to the status of a dwarf planet.)

the core of venus is very similar to the core of earth, as it is earths twin planet. therefore the the core of venus is made of the same elements as earths core, iron and nickel, both magnetic and it is these elements that create our magnetic field.
they give it a slight wobble
The two smallest major planets, Mercury and Mars, are both smaller than the estimated size of the Earth's core (combined inner and outer core).Mercury has a diameter of about 4879 km and Mars is about 6792 km, compared to the Earth's core which is a sphere about 6972 km in diameter.All of the dwarf planets (Pluto, Eris, Haumea, Makemake, and Ceres) are smaller in diameter than even the Earth's solid inner core (~2440 km in diameter), although Eris is almost as large and Pluto only slightly smaller than Eris.-The Earth's inner core has a thickness (radius) of about 1220 km.-The Earth's outer core has a thickness (radius) of about 2266 km.
== == The average density of the planet Earth is 5.52 (Standardized Result 5.52 g/cm3) the density of core of earth is 8 g/cm3

The Earths Core can be broken into two pieces the inner core and the outer core. The Inner Coreis made of SolidIron. The Outer Core is made of Liquid Iron.
scientists think that the earths core is made up of mostly iron, and contains smaller amounts of copper nickel.

A liquid rock is called magma when it is beneath the Earth's surface and lava when it reaches the surface through volcanic activity.
The Earths core is. And that would mean it is hotter than the Sun!!
Earth's core
The principle element found at the Earth's core is iron.
The molten iron and medals inside the earths core are the reasons for the earths magnetic core.
