Meteoroid impacts represent one of the most dynamic interactions between extraterrestrial bodies and the Earth’s atmosphere. When meteoroids enter the atmosphere, they experience rapid deceleration ...

Meteoroid streams are coherent groups of debris originating primarily from cometary or asteroidal fragmentation, which travel through the Solar System along similar orbital paths. As Earth intersects ...

Why do comets and their meteoroid streams weave in and out of Earth's orbit and their orbits disperse over time? Researchers show that this is not due to the random pull of the planets, but rather the ...
