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.)
What else can I help you with?
What planet is smaller than the earth's core?
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.
How might the areas of solid iron floating over the Earths molten core affect our planet's spin?
they give it a slight wobble
What other planet has a core similar to earths?
Mars is believed to have a core structure that is somewhat similar to Earth's, with a solid inner core and a liquid outer core. This similarity is based on data from spacecraft missions and studies of Martian meteorites.
What is mostly iron?
The Earth's core is mostly composed of iron, with a smaller amount of nickel. This iron-nickel core is responsible for generating the planet's magnetic field.
Which is not part of earths interior?
The atmosphere is not part of Earth's interior. The Earth's interior comprises the crust, mantle, outer core, and inner core. The atmosphere is the layer of gases that surrounds the planet and is part of the Earth's external environment.
What is earths center of the planet as the?
Core
What planet is the size of earths core?
pluto
Which planet is smaller than Earth's core?
Mars
How would you describe the earth's core?
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.
What element makes up of the earths core?
scientists think that the earths core is made up of mostly iron, and contains smaller amounts of copper nickel.
Are you closer to the earths core or moons surface when standing at sea level?
Earth's core
What on the planet earth is 7500 k for the temperature?
The Earths core is. And that would mean it is hotter than the Sun!!
Which element makes up a large percentage of Earths core and a much smaller percentage of the crust?
The principle element found at the Earth's core is iron.
The possible source of earths magnetic core is?
The molten iron and medals inside the earths core are the reasons for the earths magnetic core.
What are earths two heat engines?
the sun is the external heat engine and the core of the planet is it's internal heating engine.
What planet is smaller than the earth's core?

What is the distance of the inner core?
The earth's inner core is 3160 kilometers beneath the earths surface. The inner core is a solid ball of nickel-iron alloy.
