This article discusses the physical and kinematical characteristics ofplanetary nebulae accompanying PG1159 central stars. The study is based on theparallax and proper motion measurements recently offered by Gaia space mission.Two approaches were used to investigate the kinematical properties of thesample. The results revealed that most of the studied nebulae arise fromprogenitor stars of mass range; $0.9-1.75$\,M$_{\odot}$. Furthermore, they tendto live within the Galactic thick-disk and moving with an average peculiarvelocity of $61.7\pm19.2$\,km\,s$^{-1}$ at a mean vertical height of $469\pm79$pc. The locations of the PG1159 stars on the H-R diagram indicate that theyhave an average final stellar mass and evolutionary age of$0.58\pm0.08$\,M$_{\odot}$ and $25.5\pm5.3 \rm{x}10^3$ yr, respectively. Wefound a good agreement between the mean evolutionary age of the PG1159 starsand the mean dynamical age of their companion planetary nebulae ($28.0\pm6.4\rm{x}10^3$ yr).
