Space dust entering Earth's atmosphere

Earth encounters interplanetary dust and small meteoroids every day, but the exact mass is uncertain: scientific estimates span orders of magnitude—from a few to hundreds of tonnes per day, depending on the method and what is counted. NASA cites about 44 tonnes of meteoritic material per day, while estimates of the broader dust influx vary much more widely. Thus, 27 tonnes may be an older approximation, not a universally established constant. Most material burns up high in the atmosphere. [1–3]
