Bennu is a small asteroid compared to others in the solar system, as it is about as wide as the Empire State Building is tall (around 1,450 feet [500 meters]). Of note, it has a 1-in-1,750 chance of hitting Earth on one of its close approaches to Earth in the late 22nd century, according to NASA.
However, those aren’t the reasons that scientists are studying Bennu. Rather, Bennu was selected because of its age. The asteroid has been around for more than 4.5 billion years, and its present-day composition was likely established within 10 million years of our solar system’s formation. This makes it a great candidate for studying what the early solar system might have been like.
2. SpaceX and Boeing send humans to space
As 2023 rolls around, Boeing and SpaceX will continue to compete to launch humans into Space as a part of NASA’s Commercial Crew Program (CCP). In February, SpaceX will attempt its sixth launch for the CCP, sending four astronauts to the International Space Station.
