Webb19 mars 2024 · Our shape model indicates that, similar to other top-shaped asteroids, Bennu formed by reaccumulation and underwent past periods of fast spin, which led to its current shape. Today, Bennu might follow a different evolutionary pathway, with an interior stiffness that permits surface cracking and mass wasting. ウッドラフキー役割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. palazzo lambertiWebbAbstract The shapes of regolith particles on airless bodies, such as the Moon and asteroids, are important to understand their formation and evolution on surfaces.
