NASA: the asteroid will miss, but will approach the Earth

CAPE CANAVERAL, Florida (AP) – On Thursday night, a truck-sized asteroid will streak past Earth in what will be one of the closest such collisions ever recorded.

NASA insists it will be a near miss and there is no chance of the asteroid colliding with Earth.

On Wednesday, NASA said the newly discovered asteroid will pass at an altitude of 2,200 miles (3,600 kilometers) over the southern tip of South America. That’s 10 times closer than a bunch of communications satellites circling overhead.

The closest approach will occur at 19:27 EST (21:27 local time).

Even if the space rock were to get close, most of it would burn up in the atmosphere, and some of the larger pieces could possibly fall as meteorites, scientists say.

NASA’s collision hazard rating system, called Scout, quickly ruled out a strike, said its developer David Farnocchia, an engineer at the agency’s Jet Propulsion Laboratory in Pasadena, Calif.

“But, despite very few observations, it was nevertheless possible to predict that the asteroid will make an extremely close approach to the Earth,” Farnokchia said in a statement. “In fact, this is one of the closest encounters of a known near-Earth object ever recorded.”

The asteroid discovered Saturday, known as 2023 BU, is believed to be between 11 feet (3.5 meters) and 28 feet (8.5 meters) in diameter. It was first noticed by the same Crimean amateur astronomer Gennady Borisov, who discovered the interstellar comet in 2019. Within a few days, astronomers around the world made dozens of observations, which made it possible to refine the asteroid’s orbit.

The asteroid’s trajectory will change dramatically under the influence of Earth’s gravity as soon as it flies by. According to NASA, instead of orbiting the Sun every 359 days, it will move in an oval orbit lasting 425 days.
