Here is a piece of a protoplanet. And no doubt there was a moment of revelation for that scientist in the lab who first held it up and announced --

'Wow!' (or whatever;-) Have a good Sunday my fellow #PlanetCitizens

The mixture of the iron-nickel alloy and olivine originated from a small protoplanet out of the dawn of the Solar System. It melted from its original material of chondrite and separated into iron alloy and silicate phases (known as core and mantle). “Towards the end of the protoplanet's life,” fewthe3rd explains, “it experienced a very violent collision with another body and [this] forced the contact between the core and the mantle to become perturbed via shockwaves from the impact – hence the mixing.” Collisions like this lead to bigger bodies and eventually formed the terrestrial planets. “So this is kind of an baby picture of the Earth.”
