Abstract from DBPedia
    A micrometeoroid is a tiny meteoroid: a small particle of rock in space, usually weighing less than a gram. A micrometeorite is such a particle that survives passage through Earth's atmosphere and reaches Earth's surface. The term "micrometeoroid" was officially deprecated by the IAU in 2017, as redundant to meteoroid.

    微小隕石(びしょういんせき)とは非常に小さな隕石をいう。宇宙空間に存在する岩石の小片で、重さは通常1グラム未満である。地球の大気を通過して地表に到達する過程で残った破片が流星塵である。
