No. The other terrestrial planets likely have metallic cores similar to Earth's. The gas giants likely have rocky cores.
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 Earth's core makes up about 15% of the planet's total mass.
Pulsar planet.
Iron is found on many planets in our solar system, including Earth, Mars, and Mercury. However, the abundance and distribution of iron may vary from planet to planet. For example, iron is a major component of Earth's core, while on Mars, iron is present in the planet's soil and dust.
Yes, the Earth has a large molten core composed of iron and nickel. This core is responsible for generating the planet's magnetic field and plays a crucial role in Earth's geology and internal processes.
No, Earth is not the only planet with lava (magma), Venus has a molten core as well as Earth.
Yes, the Earth's core spins within the planet.
Yes, the Earth's core is spinning within the planet's interior.
The Earth's core makes up about 15 of the planet's total volume.
Ours - Earth.
Mars
Terribly worded question, but yes the Earth has a liquid outer core and a solid iron inner core.
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 earth is the only planet on earth.
The Earth's core makes up about 15% of the planet's total mass.

The core. The heart of the planet is called the core, Earth's core is molten while some other planets have solid cores.
