From NASA Goddard:
When NASA’s OSIRIS-REx spacecraft arrived at the asteroid Bennu in December 2018, its close-up images confirmed the mission’s prediction nearly two decades ago: Bennu is made of loose materials and gathered together due to gravity. Shaped like a spinning top. However, this major verification was accompanied by a major surprise. Scientists had expected Bennu̵7;s surface to consist of fine-grained materials (such as beaches), but was attracted by the uneven boulders-the size of a car, the size of a house, the size of a football field. Now, with the help of laser altimeter data and OSIRIS-REx’s high-resolution images, we can explore Bennu’s extraordinary terrain.
This impressive video tour about the asteroid Bennu drew a lot of criticism YouTube Because it is more about the mythical origin of the names of geological structures than the science behind the features themselves. A person’s mileage will always change. I like to hear the myth behind the name, which reminds me of the fact that even in the precise and strict scientific field, naming things requires a lot of thought, imagination and sense of humor.
