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.
No. The other terrestrial planets likely have metallic cores similar to Earth's. The gas giants likely have rocky cores.
So far as science can deduce, it must be a solid.
they give it a slight wobble

The Earths core is. And that would mean it is hotter than the Sun!!
Earth's core
The molten iron and medals inside the earths core are the reasons for the earths magnetic core.
No. The other terrestrial planets likely have metallic cores similar to Earth's. The gas giants likely have rocky cores.
the sun is the external heat engine and the core of the planet is it's internal heating engine.
The earth's inner core is 3160 kilometers beneath the earths surface. The inner core is a solid ball of nickel-iron alloy.
The Earth's center is called the core. It includes a solid inner core and a liquid outer core composed mainly of iron and nickel. The core plays a crucial role in generating the planet's magnetic field.
So far as science can deduce, it must be a solid.
