- Аннотация: We present and analyze spectroscopic and photometric observations for NGC 2685, the prototype polar-ring galaxy. The spectroscopic data were acquired using the 6 m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences with the UAGS spectrograph and a scanning Fabry-Perot interferometer, while the photometric analysis was based on images from the Hubble Space Telescope archive. We demonstrate that the subsystem usually called the \ldquoinner polar ring\rdquo is a highly inhomogeneous gas and dust disk rotating approximately in the polar plane relative to the galaxy\rsquos main body. When the self-absorption in the disk is taken into account, a comparison of its color indices with those from model computations of the color evolution of galaxies results in an age for the disk of about 1.4 \times 109 years, much lower than the previously accepted estimate.
