In order to determine the structural parameters of NGC 225, we calculated the stellar density profile in the cluster's field. We estimated the probabilities of the stars being physical members of the cluster using the existing astrometric data. The most likely members of the cluster were used in the determination of the astrophysical parameters of the cluster. We calculated the mean radial velocity of the cluster as V_r_=-8.3+/-5.0km/s from the optical spectra of eight stars in the cluster's field. Using the U-B vs B-V two-colour diagram and UV excesses of the F-G type main-sequence stars, the reddening and metallicity of NGC 225 were inferred as E(B-V)=0.151+/-0.047mag and [Fe/H]=-0.11+/-0.01dex, respectively. We fitted the colour-magnitude diagrams of NGC 225 with the PARSEC isochrones and derived the distance modulus, distance and age of the cluster as Mu_V_=9.3+/-0.07mag, d=585+/-20pc and t=900+/-100Myr, respectively. We also estimated the galactic orbital parameters and space velocity components of the cluster and found that the cluster has a slightly eccentric orbit of e=0.07+/-0.01 and an orbital period of P_orb_=255+/-5Myr.2016AdSpR..58.1900Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/ASpR/58.1900CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/453/1095 : NGC 6866 UBVRI photometry (Bostanci+, 2015)J/other/ApSS/355.267 : NGC 6811 CCD UBVRI photometry (Yontan+, 2015)J/other/ApSS/361.126 : NGC 6819 CCD UBV photometry (Ak+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/ASpR/58.1900https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/ASpR/58.1900http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/ASpR/58.1900https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/ASpR/58.1900https://vizier.iucaa.in/viz-bin/votable?-source=J/other/ASpR/58.1900http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/ASpR/58.1900GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/ASpR/58.1900/table3 (Photometric and astrometric catalogue NGC 225)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/ASpR/58.1900/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/other/ASpR/58.1900/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/ASpR/58.1900/table3?GETtext/xml+votable180.050000true10.60912561.86320560.0055555555555555566/30383.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/ASpR/58.1900?format=asciiInfraredOpticaldefaultJ/other/ASpR/58.1900/table3Photometric and astrometric catalogue NGC 225recnoRecord number assigned by the VizieR team.
