Özet:

 We present an investigation of the open cluster Trumpler 2 using Gaia DR3 photometric, astrometric and spectroscopic data. 92 stars were identified as likely members of the cluster, with membership probabilities greater than 0.5. The mean proper-motion components of the cluster are derived as  cos , 1.494  0.004, 5.386  0.005 mas yr1 . By comparing the Gaia based colour-magnitude diagram with the PARSEC isochrones scaled to   0.0088, age, distance modulus and reddening are simultaneously estimated as   11010 Myr,   10.0270.149 mag and BP RP  0.4520.019 mag, respectively. The total mass of the cluster is estimated as 162  based on the stars with membership probabilities   0. The mass function slope is derived to be Γ  1.33  0.13 for Trumpler 2. This value is in a good agreement with that of Salpeter. Galactic orbit analyses show that the Trumpler 2 orbits in a boxy pattern outside the solar circle and belongs to the young thin-disc component of the Galaxy.
