The following is a list of
bolides and fireballs seen on Earth in 2017. These are small asteroids (known as
meteoroids) that regularly impact the Earth. Although most are so small that they burn up in the atmosphere before reaching the surface, some larger objects may reach the surface as fragments, known as
meteorite
A meteorite is a solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the atmosphere to reach the surface of a planet or Natural satellite, moon. When the ...

Meteors with a recorded

American Meteor Society are only listed if observed by at least 10 people, and are cross-referenced wit
