Using 20 radar images of asteroid 2004 BL86 as it flew past Earth on January 26, scientists at JPL have created a movie showing the orbital motion of the asteroid’s moon.
The images also show one of the most spherical asteroids I have ever seen. Like Ceres, the larger size has helped shape the asteroid into a more typical-looking planetary sphere.
