The aim of this work is to explore the population of wide companions of nearby young stars using data from GAIA satellite. To achieve this goal, we have performed an astrometric and photometric search for companions with common distance and proper motion using GAIA DR3 (Data Release 3), in combination with other photometric catalogues such as 2MASS. The search has been performed on the following YMGs: TW-Hydrae (TWA; 10 Myr, 60 pc), 32 Orionis (32ORI; 22 Myr, 96 pc), βPictoris (βPIC; 24 Myr, 30 pc), Columba (COL; 42 Myr, 50 pc), Tucana-Horologium (THA; 45 Myr, 46 pc), Carina (CAR; 45 Myr, 60 pc), Volans-Carina (VCA; 90 Myr, 86 pc), AB Doradus (ABDMG; 150 Myr, 30 pc), Carina-Near (CARN; 200 Myr, 30 pc) y Oceanus (OCE; 500 Myr, 2-50 pc).
