(meteorobs) Re: meteor showers

[Robert Lunsford]

Gilles and All,

Everything in space is in motion. Particles such as meteors may be in orbit 
in any direction at various velocities. The angle at which it encounters the 
Earth has a great deal to do with the velocity that we see it move through 
the sky. Meteors moving in the same direction as the Earth will appear to be 
moving much slower than those encountering the Earth in the opposite 
direction. It may be interesting to know, for the most part, that at dusk 
all the meteors you see are catching up to the Earth. Those seen at dawn are 
colliding with Earth head-on and will usually appear to move swiftly. At 
midnight you can see a combination of the two, radiants in the west 
producing slow meteors and those in the east producing swift ones.

I hope this helps!

Robert Lunsford
