We use new memberships from Gaia DR2 to investigate the shape of the nearest open clusters. We investigate their 2D distribution projected on the sky and fit two gaussians components on the central part and external envelope. For open clusters closer than 200 pc from the Sun, we fit 3D ellipsoids on the spatial distribution of the members. We look for correlations of the spatial properties with age and galactic environment.Read less <
