Thats 19,130434783 galactic years.. so in theory that sort of debris once caught could come from anywhere in the galaxy we tumbled through
- dotancohen 5y agoThe meteor was not flung out of an exploding sun. The elements that would later form the metor - iron for instance - were flung out of an exploding sun. This likely happened far earlier than the 4.4 billion year age of the rock. Considering _that sun_ was itself a second population sun, that event probably happened closer to 6 to 8 billion years ago (personal estimate based on the lifetime of third- and second- population stars and the estimated age of the universe). And it wasn't solid iron at that point, rather disperse iron atoms.
