An

asteroid the size of a truck

passed close to Earth on Thursday in

one of the closest approaches ever recorded

, space scientists have reported.

The

asteroid 2023 BU

, recently discovered by an amateur astronomer, passed through the southern tip of South America at around 4:29 p.m. local time (01:24 a.m. Spanish peninsular time), according to the North American space agency

NASA

.

At its closest,

the rock has come to be just 2,200 miles (3,600 kilometers) from Earth's surface

, much closer than many geostationary satellites orbiting the planet.

The rock was discovered on Saturday from an

observatory in Crimea

by amateur astronomer

Gennadiy Borisov

, who had already detected an

interstellar comet in 2019.

Dozens of sightings were then made at observatories around the world, and the

impact risk assessment system NASA's

Scout

quickly ruled out an asteroid impact on Earth, the space agency said.

Despite making few observations, Scout was able to predict that the asteroid would "come extraordinarily close to Earth," said

Davide Farnocchia

, who helped develop the Scout system. "In fact, this

is one of the closest known approaches to an object ."

to Earth ever recorded

," he added.

But even if the calculations had been wrong, humanity would have been safe, according to scientists.

With a length of only 3.5 to 8.5 meters,

2023 BU is too small to cause significant damage

and would have caught fire upon entering the atmosphere.

The few meteorites that have made it to land are small, not like the huge blocks that destroy cities and cause tsunamis in the movies.

Its approach to Earth will have a more lasting impact on the asteroid, according to NASA mathematicians.

Earth 's

gravity will extend the time it takes for the asteroid to complete its orbit

around the Sun, from 359 days in the past to 425 days, according to NASA.
