The asteroid Ryugu is being approached by the Japanese space probe Hayabusa2. The craft will eventually land on the asteroid, collect mineral samples, and return them to Earth.

For now, we have the animation sequence, linked below. It is made of images of the asteroid as it rotates. These are processed with red and cyan filters to produce three dimensional images.

To view this movie, one needs to watch through similarly colored 3D glasses; red for the left eye, cyan for the right. These glasses are widely available.

The rotation of the asteroid is represented in two sequences, in the upper one, the rotation is very rapid, to give a good impression of smooth motion, In the lower, the rotation proceeds much more slowly, step by step. This enables closer study of details of the asteroid's terrain.

For those without access to 3D colored glasses, A conventional 'movie' of the asteroid rotating is available at the link, below. The most interesting feature on Ryugu is the light-colored object near the top of the image.

One is reminded of the especially bright spot on the asteroid Ceres, in the Occator crater. This isn't a flattish spot, though, but more like a boulder. Ryugu seems too small to have geological layering, like salt deposits that can be driven to the surface by impacts, which is probably what happened at Ceres.

This light-colored object is notable for having at least two quite flat, vertical surfaces, almost as if rough surfaces had been sheared off. These surfaces are quite efficient at catching and reflecting sunlight.
