Is it likely that every planet has all the same elements we do?

So what's the likelihood of a planet consisting purely of chocolate?

That's the real question at hand here. Near infinite Universe, near infinite permutations and possibilities, quantum fluctuations and BAM! Chocolate world.

Chocolate? About zero. Diamond? About 100%, if our observations are correct, though it's about the size of a planet, astronomers might call it something else like a stellar remnant.

Astronomers Find a Huge Diamond in Space

The newly discovered cosmic diamond is a chunk of crystallized carbon 50 light-years from the Earth in the constellation Centaurus. (A light-year is the distance light travels in a year, or about 6 trillion miles.) It is 2,500 miles across and weighs 5 million trillion trillion pounds, which translates to approximately 10 billion trillion trillion carats, or a one followed by 34 zeros.


By the way even within our solar system, Mars and Earth have different composition, that's how we can tell when someone finds a rock from Mars on Earth that it's a Mars rock, because it matches Mars composition and not Earth composition, which involves not only elemental composition but also isotope ratios.

Of course planets around a first generation star will have a vastly different composition with much different metallicity (composition of hydrogen versus heavier elements).
