Venus is called a terrestrial planet because it has a solid rocky surface, like Earth does. The other type of planet in this gas is a gas giant or Jovian planed, consisting largely of hydrogen gas, like Jupiter.
Earth has a solid metal inner core and a liquid metal outer core. Most of the rest made up of rocks in a molten state, but with a solid "crust". Finally there is a gas atmosphere.For simplicity scientists call Earth a solid planet to distinguish it from the gas planets, like Jupiter.
The planet with a core of nickel and iron and a crust 600 km thick is Mercury. Mercury's core makes up about 85% of its radius and is composed mainly of iron with some nickel. Its crust is thin compared to its core and mantle.
Mercury comes in 2nd place - average density (5.44 g/cm3 == ==
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.
The planets closer to the sun tend to have rocky crust and dense cores.

Venus, Earth and possibly Mars. Mercury's density is too low for Mercury to have a dense core.
It would be Venus, because that planet is the only one that has a solid crust.
Because Mercury is one of the inner planets with a rocky crust and an Iron Core.
No, it has a dense rocky core in the middle!!
The crust is the least dense. The inner core is the most dense. So from the middle outwards the layers get less and less dense
The outer core, inner core, mantle, crust, water, atmosphere. This is the order from densest to least dense.
inner core outter core mantle and crust
Mercury is considered the smallest rocky planet in our solar system. It has a rocky core and is closest to the Sun.
The inner core is the least dense out of the inner core, outer core, mantle, and crust. It is composed mostly of iron and nickel, making it very dense despite being solid.
