The kinematics and distribution of young stellar objects (young open clusters, OB-associations, classical Cepheids) within ~3 kpc from the Sun suggest the existence of the outer ring R1R2 in the Galaxy. "The fork-like" structure in the distribution of young objects in the Galactic disk can be interpreted in terms of the R1R2 morphology: at longitudes l>180 two outer rings fuse together to form one spiral fragment -- the Carina arm, whereas at longitudes l<180 two outer rings run separately producing the Sagittarius and Perseus arm-fragments. The optimum value of the solar position angle with respect to the major axis of the bar, b, providing the best agreement between the distribution of young objects and model particles is b=40±13. We study the distribution of young objects with radial residual velocity directed toward the Galactic center, which inside 3 kpc of the Sun must belong to the outer ring R2. The selected objects and model particles demonstrate similar distribution in the Galactic plane: both samples concentrate to the fragment of the leading spiral arm. The appearance of the leading fragment suggests that the Sun is located near the descending segment of the ring R2. Moreover, selected objects and model particles exhibit similar variations of azimuthal residual velocity VT in the direction of Galactic rotation. The sharp rise of extinction toward of the Galactic center can be explained by the presence of the outer ring R1 near the Sun.
