Meet Bennu, the 510m-wide asteroid that could hit Earth in 2182.
Granted, the chances are small—just 0.057%—but it's enough of a concern that NASA has given it some close attention.
The OSIRIS-REx spacecraft visited Bennu in 2018, mapping its surface and collecting 60 grams' worth of samples for return to Earth in 2023.
Modelling has suggested Bennu's close approach will happen in 2135—and what happens next will depend on whether or not Bennu reaches Earth's "gravitational keyhole".
Entering such a location, at just the right time, would see Earth's gravity bend it towards a likely impact in 2182.
Given the slim chances, there's not too much to worry about. But if you've got plans for 2182, you may want to check the skies before you head out ☄️
