A small asteroid will come closer to the Earth than some satellites on Thursday evening, passing over the southern tip of South America, writes NASA. Expected to pass over at 7:27 pm EST, the asteroid does not pose a risk to the planet.
The asteroid, called 2023 BU, was discovered by Gennadiy Borisov, an amateur astronomer, from his observatory in Nauchnyi, Crimea, reports The Wall Street Journal. Within three days of the discovery, multiple observations allowed for the path of 2023 BU to be refined. Approximately 100 tons of space material makes it to Earth every day, however, most of it is small, going undetected. But scientists are working to better detect objects approaching Earth to prevent larger damage, which was the goal of NASA's DART mission in 2022.

"Besides discovering objects, we are also making preparations to be able to deflect them in case that was ever needed," said Farnocchia. "The DART mission is a great example of that."
Once 2023 BU passes Earth, its "orbit will be more elongated, moving it out to about halfway between Earth's and Mars' orbits at its farthest point from the Sun," and will "complete one orbit every 425 days."
