What is the most metal rich terrestrial planet?
Mercury's density implies that 65% of the planet is metal-rich core, thus it would be the most metal-rich of the terrestrial planets.
Do all the planets have a core?
Yes Pluto has a core. It is believed that it's rocky material would have settled into a dense core surrounded by a mantle of ice. The diameter of the core should be around 1,700 km, 70% of Pluto's diameter.
What gives heat and light to all the planets?
Nuclear Fusion and Fission from the Suns' core.
What is the composition of the inner planets?
core
Which planet has a rocky crust and dense core?
The four planets closest to the Sun all have rocky crusts and dense cores. These planets are Mercury, Venus, Earth, and Mars.
Do all planets have liquid metal in the core?
no, because liquid metal is usually created through electromagnetic fields or friction.
What do all planets have?
All planets have a core.
Are all planets made of metal?
No, but they all seem to have metal cores. Minor planets are not so consistent.
Do all planets have a hot core?
yes
Do all planets have a molten core that has liquid metal?
Only the Earth is known to have a core that includes liquid metal.However, Jupiter and Saturn do have regions composed of metallic liquid hydrogen. Also, there is some evidence that Mercury and Venus may have liquid metal in their cores. Mars may have some liquid metallic sulfide in its core.
What is the most metal rich terrestrial planet?
Mercury's density implies that 65% of the planet is metal-rich core, thus it would be the most metal-rich of the terrestrial planets.
Do planets have light of their own?
no planets crust does not have light of their own but the core of the earth has light of its own
What planets are rock planets that the just the planets core made from rock?
there are 9 planets
How they are alike inner planets and outer planets?
They are alike because they are both called planets, both terrestrial planets and gas giants are spheres, all have a somewhat dense core and lastly all orbit around the sun.
Do all the planets have a core?
Yes Pluto has a core. It is believed that it's rocky material would have settled into a dense core surrounded by a mantle of ice. The diameter of the core should be around 1,700 km, 70% of Pluto's diameter.
What evidence led the conclusion that earth core is made of solid iron?
The effect that Earth's gravity has on other planets and the sun can be calculated. This degree of gravity that is demonstrated points to a heavy core that is metal. Fragments of nickel-iron meteorites that are remnants of planetary collisions also indicate that other planets have a nickel-iron core.
What gives heat and light to all the planets?
Nuclear Fusion and Fission from the Suns' core.
