Abstract : Open clusters (OCLs) are located in the Galactic disc. It is important to determine their properties and spatial distribution to understand the structure and evolution of the Milky Way. Therefore, investigation of the OCLs and, in particular, the estimation of their physical parameters like age, distance, reddening, size and metallicity are very valuable. The main aim of this paper is to study the astrophysical behaviour of poorly studied open star cluster NGC 5617 towards, longitude (l)=-45 deg in the Galactic plane. For this purpose we have used the PPMXL, 2MASS, VVV survey, ISOGAL and GLIMPSE data. The stellar density distribution and color-magnitude diagrams are used to estimate the geometrical structural parameters (cluster center, cluster radius, core and tidal radii, the distance from the Sun, Galactocenteric distance and the distance from the Galactic plane). Also, the main astrophysical parameters i.e. age, color excesses, total mass, relaxation time, dynamical evolution parameter, luminosity function, mass function and mass-segregation are also derived for this cluster. Results will be discussed in poster/oral.
