Different for each planet. Earth has a core of molten iron and rock. The Moon appears to be solid to the core, having cooled a long time ago.
Venus is probably still molten at the core; heck the SURFACE is nearly molten. Mars is smaller and further away, so may have a small molten core or may be solid iron and rock.
The gas giant planets may have small rocky cores, or may be gasses compressed to metallic solids by the immense pressure. We will have to do more studies to find out.

Would all eight planets fit inside the sun fit inside the sun?
99.8 percent of the total mass of our solar system is the Sun, and most of the rest is Jupiter. If there were 500 planets the size of Jupiter, they would STILL all fit inside the Sun.
All of the planets could easily fit into?
All of the planets except Jupiter could fit inside Jupiter. Jupiter is bigger than all the other planets combined. All the planets including Jupiter could easily fit inside the sun, which weighs more than a thousand times all the rest of the solar system combined. If the planets were collapsed into neutronium, their combined volume would be significantly less than 1/4 mile (that of typical neutron stars), which could probably fit inside the Grand Canyon, and perhaps even a big warehouse. Of course, this mass would also be very heavy.
What planets take less time than Saturn to orbit the sun?
All of the planets inside of Saturns orbit.Thus Mercury, Venus, Earth, Mars and Jupiter
Why are some planets referred to as the inner planets and others as the outer planets?
Because the four inner planets (Mercury, Venus, Earth, Mars) are the four planets closest to the sun. These smaller planets are all inside the asteroid belt. The larger planets: Jupiter, Saturn, Uranus, Neptune) are outside the asteroid belt and thus called the outer planets.
What is the setting of the planets from the Hitchhikers Guide to the Galaxy?
The planets are shown on the inside of the planet Magrathia. They actually manufacture planets to order.
How big are planets?
well some planets are bigger than the earth but from the inside earth is of course bigger than all of the other planets
Can Jupiter fit all the planets inside it?
Yes it can includuing saturn.
What is the difference between planets inside the Asteroid belt and planets outside?
The planets inside the steroid belt will get hit and the other planets will not.
what other planets are nearby to Jupiter?
Jupiter is the largest planet in the solar System so any of the other planets could fit inside a volume the size of Jupiter, some of them many times over.
All the terrestrial plannets lie inside the asterorid belt True or false?
All Planets do not lie inside the asteororid Belt . The answer is False
Why is planet Mercury the fastest in its orbit?
Because it is nearer to the Sun than all of the other planets. Its orbit is inside that of all of the other planets, so it shorter.
Would all eight planets fit inside the sun fit inside the sun?
99.8 percent of the total mass of our solar system is the Sun, and most of the rest is Jupiter. If there were 500 planets the size of Jupiter, they would STILL all fit inside the Sun.
What planet is so large that all the other planets could fit inside it?
Jupiter
What are all of the planets that are inside th asteroid belt?
Mercury, Venus, Earth, and Mars.
What does other planets have inside them?
In our solar system all the planets (and Sun) formed from one collapsing nebular. Therefore all the planets have the same stuff inside them. The differences between planets is caused by the differences in their outer layers as the planets formed at different distances form the Sun where the temperatures gradients allowed the condensation of different compounds. When you consider Xenoplanets, we do not know hat they are made of exactly yet.
What planets are biggher then earth?
Inside our sollar system, the planets Jupiter, Saturn, Uranus and Neptune are all larger and more massive than Earth.
How big is the plannets all together?
All the planets in the solar system can fit inside of Jupiter with room to spare. So, all the planets put together would almost be twice the size of Jupiter.
