7. Sounds like homework, and I'll bet the answers are in your book.
   
   If you mean which planet in our solar system:
   
   Jupiter
   
   Neptune
   
   Venus
   
   Neptune
   
   Mercury
   
   Mercury
   
   One (Earth)
   
   
   
   If you mean planets outside our solar system (and we have found over 200 so far), we don't know as we don't have enough data on those worlds yet.
   
   
   
   As far as we know, there is just one universe ("uni" means "one" by the way - that's how they got the name).
   
   But there are theories that suggest that ours is one in an infinite number of universes making up the "multiverse".
