Webb10 nov. 2014 · Bennu is an Apollo-type NEO with a semimajor axis of 1.126 AU and an eccentricity of 0.204, resulting in perihelion of 0.897 AU and aphelion at 1.36 AU (Fig. 2 ). The orbital inclination is 6.03° and the orbital period is 1.20 yr. As a result, Bennu makes a close approach to the Earth every 6 yr.
