The incoming asteroid, called 2023 BU, does not pose a threat to Earth, NASA says.
t 2023 BU is about 11.5 to 28 feet wide, which is small enough to mostly burn up in our atmosphere if it were to hit us2,200 miles above the southern tip of South America on Thursday, January 26,hazard assessment system.
“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 NASA Jet Propulsion Laboratory who developed Scout. “In fact, this is one of the closest approaches by a known near-Earth object ever recorded.”2023 BU is passing closer to us then some of the satellites orbiting our planet, and Earth’s gravity is changing the asteroid’s path around the Sun from circular to more elongated. The asteroid was
discovered by Gennadiy Borisov at the MARGO observatory in Nauchnyi, Crimea on January 21. Since then, observatories across the planet have also detected 2023 BU, leading to robust models of the asteroid’how robust humanity’s asteroid detection workflow is becoming
