Reply to comment by Global_Lavishness_88 in Does the metal in the solid core of a rocky planet have any special properties? by VillagerNo4

Is the reason they are rare is that they are Siderophilic ?

Their abundance in the initial cloud that the solar system formed from would be tied to how likely they are to form during a supernova. That’s nuclear physics not chemistry.

Also a question of how astrological bodies are formed. There's a large amount of those elements that are easily accessible in asteroids. If there was ever a reason to asteroid mine, it would be for those elements. Iron being pretty prolific in general and in asteroids probably does go well with their siderophilic properties, which is probably why we tend to find those elements in large amounts in asteroids.
