Micrometeorite, collected from the Antarctic snow, was a micrometeoroid before it entered the Earth's atmosphere
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.[1]
