Title:Galaxy Structure with VVV SURVEY 

Abstract:
Use of variable stars and star counts have been used several times to understand and recognize the Milky 
Way internal structure. Infrared photometry allow us to see far away, even through high extinction zones 
and then to understand better the internal structure of our Galaxy.
Here we present the first results of VVV Survey and a  first estimative of the Galactocentric distance using 
RR Lyrae stars.
