Asteroid to come ‘extraordinarily close’ to Earth: Nasa

WASHINGTON: A truck-sized asteroid will pass near Earth on Thursday in one of the closest approaches to our planet ever recorded, Nasa said, emphasising that it poses no danger.

Asteroid 2023 BU, which was recently discovered by an amateur astronomer, will zoom by the southern tip of South America at around 4:27 pm PST on Thursday (0027 GMT Friday), according to Nasa.

It will pass just 2,200 miles from Earth´s surface, much closer than many geostationary satellites orbiting the planet. But there is no risk that the asteroid will hit Earth, Nasa said in a statement on Wednesday.

Even if it did, the asteroid measuring 3.5-8.5 metres across would largely disintegrate in the Earth´s atmosphere, potentially just resulting in a few small meteorites. It was discovered on Saturday from an observatory in Crimea by amateur astronomer Gennadiy Borisov, who previously spotted an interstellar comet in 2019.

Dozens of observations were then carried out by observatories across the world. Nasa´s Scout impact hazard assessment system quickly determined that the asteroid would miss Earth, the US space agency said.

“Despite the very few observations, it was nonetheless able to predict that the asteroid would make an extraordinarily close approach with Earth,” said Nasa´s Davide Farnocchia who helped develop Scout.
