Certainly, a planetary core can be cold. The heat of our own planetary core is the result of radioactive decay of various elements in the core and mantle, but eventually that heat source will be used up, and the residual heat will gradually leak away into space. There could be other planets which never had much or any abundance radioactive content in the first place.

The planetary surface that best fits this description is Mars. Mars has a dry and cold climate, with temperatures averaging around -80 degrees Fahrenheit. Its surface features include vast deserts and canyons, making it a cold desert planet.
very, very cold
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.
Mars is a planetary body.
After a planetary nebula occurs, the core of the star collapses and becomes a white dwarf. This white dwarf slowly cools down over billions of years until it eventually becomes a cold, dark remnant known as a black dwarf.
When the core of a star blows its surface into space to form a planetary nebula, it sheds its outer layers of gas, exposing the hot, dense core of the star called a white dwarf. The white dwarf emits ultraviolet radiation that ionizes the ejected gas, causing it to glow and form the planetary nebula.
The crust is brittle and cold but the outer core is fluid in state.

When a planetary nebula dissipates, what remains is the core of the star that has shed its outer layers. This core, known as a white dwarf, is extremely dense and hot, gradually cooling over billions of years. The planetary nebula itself, which is the glowing gas and dust expelled by the dying star, eventually disperses into space.
