Um…..how does this happen with a rock?
How does a rock go from 122kg to 59kg? The USPS hadn’t been invented, must have been FedEx damaged in shipment. Lucky it even made it to earth...
The article says various people and institutions kept chipping away samples from the stony meteorite, reducing its original 127 kilogram mass to 55 before it was finally returned to the church. (After French revolutionaries had removed it.) Its density should have remained the same, if it was homogenous in composition throughout, if that’s what you mean.
Aside: Through gifts and thefts, only a fraction of the rocks the Apollo missions brought back from the moon remain in NASA’s keeping.
Uh, people kept chipping off chunks of it.
