Does Bennu pose a risk to Earth? (AndAnd how can OSIRIS-RExREx's mission save us?)
OSIRIS-REx has launched and is on its way to 101955 Bennu to divert it away from Earth - it's basically Armageddon in real life...
This is from Osiris-Rex's Wikipedia page:
...asteroid Bennu is a threatening Earth impactor capable of causing vast destruction and death
It isn't billed as the primary mission objective (probably to prevent panic), but among the objectives is diverting Bennu away from an impending impact with Earth - perhaps a "Deep Impact".
What is the chance that Bennu will impact Earth?
What is the potential for damage if it does hit?
How will information from Osiris-Rex divert Bennuaffect an impact mitigation mission?
Bonus question: When will Bennu (potentially) impact with Earth?
