Abstract:   
Recently there have been a number of detections of extra-solar giant 
planets ("hot jupiters") that transit close in front of their parent 
stars, and thus permit our first measurements of the true mass and 
radius of these enigmatic objects.  At the same time, the precision 
of stellar radial velocity measurements has improved to the point that 
a few extrasolar planets have been detected with minimum masses much     
less than Jupiter - in fact more like the mass of Uranus or Neptune           
 
in our own solar system.  Are these objects huge earth-like rocky             
  
planets, or are they more like the "ice giants" Neptune and Uranus?           
  
Detection of a low-mass planet transiting in front of its star might          
  
give the answer.  In the meantime, we can speculate about what these          
  
new discoveries can tell us about the origin and evolution of planetary 
systems in general.
