This mosaic of Bennu was created using observations made by NASA’s OSIRIS-REx spacecraft that was in close proximity to the asteroid for over two years.

In 2182, It Could Be Cloudy With a Chance of Asteroid

Scientists calculate Bennu will come close, but will most likely miss Earth in about 160 years

Using the detected radio wave, Collinson and his team calculated the density of Venus' ionosphere and compared it to measurements taken back in 1992 using the Pioneer Venus Orbiter.
