But every day, hundreds of tons of small interplanetary objects enter Earth's atmosphere. Scientists estimate that Earthgrazing meteoroids only occur just a handful of times per year. Most of them disintegrate, possibly with pieces reaching the ground as meteorites. Particles (neutral atoms) ejected by the meteoroid.

A meteoroid is a small rocky or metallic body travelling through space. Dennis Vida, a physics postdoc from Western University in Ontario, Canada, who leads the GMN, said they traced the rock to a Jupiter-family orbit, but a search of potential parent bodies found no conclusive matches.
