将已知近日点距离小于 1 au 的周期性彗星的速度分布与从地球观测到的流星体的速度分布进行比较。分布相当相似。流星星等和电子线密度取决于撞击速度的事实似乎被与流星体及其母彗星的轨道周期的倒数成正比的流星体空间密度所抵消。
The velocity distribution of the known periodic comets with perihelion distances less than 1 au is compared with the velocity distribution of the stream meteoroids observed from Earth. The distributions are reasonably similar. The fact that meteor magnitude and electron line density are dependent on impact velocity seems to be more than counterbalanced by the meteoroid spatial density being proportional to the inverse of the orbital period of the meteoroids and their parent comet.
