Fragment #443 of the Luna 16 sample is of extra-lunar origin. It was probably delivered from an LL chondrite asteroid around 1 Gyr ago, directly as a micrometeorite or as a result of a bigger impact, and never experienced temperatures higher than 400 °C since its formation. Its characteristics are compatible with a stony parent body coming from the Flora family.
