The vast majority of annual meteor showers are caused by comets which are often described as "dirty snowballs" because they consist of ice and dust. As comets approach the sun, a tail appears which is caused by the solar wind. This tail is made up of gas and dust and leaves behind a trail as it orbits the sun.
If the Earth happens to pass near enough to one of these trails, the small dust particles (meteoroids) left behind enter the Earth's atmosphere and can be visible as a meteor shower. The Earth passes through these trails at the same point in its orbit each year so the showers are annual.

You've happened to mention the Geminids which are rather unusual in the way that they don't have a parent comet. Instead they appear to have a parent asteroid which is strange because asteroids are composed of rock/metal and shouldn't leave a trail like comets do. One theory is that this asteroid is an old comet which passed too close to the sun, causing the ice to vapourise and the comet to become extinct.

And with that, first post!

Hehe, I love meteor showers, and yet I have a lot of friends who have never seen a single meteor. If only people took a bit more time to look up at the sky. They don't know what they're missing.

The lyrids are coming up soon which I'm looking forward to. I believe they peak on the 22nd if anyone else is interested.

Neily You should use your extention Ladder and get up on your foof and watch from there above all the houses around you! It would be a good view! That is if it is not cloudy as you said!

Hi Karen Mam,

That's a great idea...I might find Santa stuck down my chimney !!..LOL...the best place to go of course is where there is no light pollution...I bet this would be easy for you yes Mam ?

hugs & shmishes

Yes It it pitch dark here at night! we have very little light. A few small ones down the road at the mill, but overall very dark here! what is the geminid shower? Would that mean to look in the sky around  the star clusters in Gemini??

Hugs

Yep, meteor showers are named after the part of the sky they appear to come from.

You're very lucky to have such little light pollution. It's really bad around where I live. :(
