The inner planets, Mercury, Venus, Earth, and Mars, vary in size. Mercury is the smallest, with a diameter of about 4,879 kilometers, while Earth is the largest, with a diameter of about 12,742 kilometers. Venus falls in between Mercury and Earth, with a diameter of about 12,104 kilometers. Mars is the second smallest, with a diameter of about 6,779 kilometers.
Remembering that there is an inner core inside the outer core - the radius of the outer core/mantle boundary is about 3,400 km. (the diameter is twice the radius).
The diameter od mercurys core is 3,600 km, 2,235 miles.
The core of the Earth, about 4,216 kilometers across and 2635 miles, is thought to be divided into an outer core of liquid iron and a nearly solid iron inner core about 1,500 miles in diameter.
idek what 2 say???
Seismic data was used to estimate the radius of the Earths core. Inner = 1,221 km Outer = 2,259km Total = 3,480km Therefore an approximate diameter to the Earth core is 6,690 km or 4,325 miles. See related link for more information.
Earth's core
The Earth's core is about 1200km thick. it is mostly iron, and is solid due to extreme pressure. The temperature can be up to 7000 degrees.
Mercury's diameter (at the equator) = 4880km or 0.3825 x Earths diameter Venus' diameter = 12,104km or 0.9488 x Earths Earth's diameter = 12,756km Mars' diameter = 6794km or 0.5323 x Earths Jupiter's diameter = 142,984km or 11.21 x Earths Saturn's diameter = 120,534km or 9.45 x Earths Uranus' diameter = 51,114km or 4.01 x Earths Neptune's diameter = 49,532km or 3.88 x Earths (Pluto's diameter = 2306km or 0.18 x Earths) I included Pluto on the end there, its not classed as a planet any more though, but a dwarf planet.
The molten iron and medals inside the earths core are the reasons for the earths magnetic core.
Define Core Diameter Mismatch
no it is not true. there is solid iron and nickel in the Earths core
Earths core
The core is 33% of the Earths mass
No the earths core is not a cause of globel worming
