The invention relates to an aeronautical thruster (10) having a longitudinal axis (X) and comprising a hub (12), an upstream annular row (14) and a downstream annular row (16) spaced apart from one another along said longitudinal axis (X), the upstream annular row (14) being rotatable about the longitudinal axis (X), and the downstream annular row (16) comprising a first blade (18a) and a second blade (18b) each extending in a radial direction so as to define a radial dimension between the hub (12) and a radially outer end of the corresponding blade (18a; 18b); wherein, observed angularly about the longitudinal axis (X), the second blade (18b) is positioned closer to an angular position at 3H or an angular position at 9H than the first blade (18a), and the radial dimension of the first blade (18a) is greater than the radial dimension of the second blade (18b).
