Dear Smantha,
I've got a friend who is trying to photograph planets around other stars...Here's his answer to your question:
> How many stars in our galaxy may be like our own sun, and could many of them have planets around them?
Mais oui!
About a billion, and absolutely yes.
Seen one star, seem 'em all. I.e., if our fairly typical middle-of-the-range star is like this, I imagine
that other similar stars aren't likely to be all that different. But of course the planets may all have completely different sizes and arranged
in different orbits.
