An asteroid just hurtled past Earth in an event described by NASA as “one of the closest approaches by a near-Earth object ever recorded.”
Asteroid 2023 BU zipped by at 7:27 p.m. , passing over the southern tip of South America a mere 2,200 miles from Earth’s surface — a distance that put it well within the orbit of geosynchronous satellites.
The asteroid was first sighted by amateur astronomer Gennadiy Borisov as he looked out from an observatory in Crimea last Saturday. Following additional sightings by observatories around the world, astronomers were able to nail down 2023 BU’s orbit. “Scout quickly ruled out 2023 BU as an impactor, but despite the very few observations, it was nonetheless able to predict that the asteroid would make an extraordinarily close approach with Earth,” said Davide Farnocchia, a navigation engineer at JPL who developed Scout. “In fact, this is one of the closest approaches by a known near-Earth object ever recorded.”
