Its eccentric orbit modulates the X-rays observed from the wind-wind interaction, and its large separation allows for spatially resolving both components.\n  Aims. We aim to strengthen the constraints on gamma2 Velorum's properties and, in particular, solve the discrepancy between the eccentricity determined from the emission lines and that from the absorption lines.\n  Methods. We obtained VLT/GRAVITY observations and combined them with earlier spatially-resolved data at different orbital phases.\n  Results.
