Here, we explore some peculiar orbital features of the recently discoveredasteroid A/2017 U1, which is a clear outlier when considering the average valueof the eccentricity of known hyperbolic comets. As for the orientation of itsorbit in space, the orbital plane of A/2017 U1 seems to be away from anyobvious clusters present for this population. The orbital nodes of A/2017 U1are well away from the paths of the planets of the Solar System and the Sun.All these orbital properties appear to confirm A/2017 U1 as the first knowninterstellar asteroid.
