Hi all,
Firstly thanks to everyone for their help so far i am loving this hobby of 3 months...
i have few questions/myths... like a good astronomer should I am having some friends around (mainly kids) next weekend as they saw my telescope and wanted a look through.
I'd like some easy to understand figures and facts that they could grasp to amaze them with.

i know its a big ask.

Things like...
What is the nearest star (except the sun ! Ha Ha), how far away is it....light speed will mean nothing to kids so if I drove in my car at 100kms an hour...how long will I be driving...(Actually if you give me the distance I could probably work it out.)

i once heard there are more stars in the universe than grains of sand on all the beaches in the world...is this true? because it sounds good...

Also most of the stars we are looking at in the night sky are from our own galaxy right?....and ours is just one of thousands, millions...trillions in the universe.

Finally if anyone has some cool "easy to grasp examples" of space cool stuff that would also be good....

thanks dudes
Steve
