<u>1. Chondrite </u>dating on the primitive meteorites that have been collected show that they are around 4.6 billion years old.
Chondrites are described as stony meteorites generally unmodified by changes to the parent body such as melting induced by high heat or becoming differentiated by separating into constituent layers. Chondrite-dating utilizes isotopes of lead, 206Pb/204Pb to provide age or chronometric estimates of around 4.6 billion years- this is further confirmed via their composition, which consists of stable, nonvolatile elements common in stars within this galaxy.
