![]() ![]() Scientists tell us that asteroid Bennu has been a silent witness to titanic. NASA has a good explanation of the Yarkovsky effect and its impact on Bennu traveling through gravitational keyholes in the video below. Stay tuned here for Kens continuing Earth and planetary science and human. inside the clays that make up its scientific target, the asteroid Bennu. Yarkovsky effect measurements from the OSIRIS-REx probe were thus used to fine-tune Bennu's trajectory. This mosaic image of asteroid Bennu is composed of 12 Pol圜am images collected. The effects are minuscule though can adjust Bennu’s motion over long-enough periods of time. ![]() The heat is then radiated back into space as it cools down, releasing infrared energy that generates a small push on the asteroid. ![]() As Bennu spins, the side of its body facing the Sun absorbs heat and rotates away. NASAs OSIRIS-REx spacecraft has been orbiting an asteroid called Bennu for more than two years to fine-tune the agencys existing models of its trajectory.
