[New Tang Dynasty News, Beijing time, January 29, 2023]The National Aeronautics and Space Administration (NASA) means that a truck-sizedasteroidOn the afternoon of the 26th (the morning of the 27th Taiwan (Beijing) time), it passed over the southern tip of South America.EarthSatellites in geostationary orbit are even closer.
The Central News Agency quoted Agence France-Presse as reporting that, according toNASAThe claim, recently discovered by amateur astronomersasteroid「2023 THIS” will pass over the southern tip of South America at around 4:27 pm Pacific Standard Time on the 26th (8:27 am Taiwan Time on the 27th).
At that time, the asteroid will be only 2,200 miles (3,600 kilometers) from the surface, less than manyEarthSatellites in geostationary orbit are even closer.
But NASA said in a statement yesterday that there is no risk of the asteroid hitting the Earth.
Even if it was risky, the asteroid, which is about 3.5 to 8.5 meters (11 to 28 feet) in diameter, would probably disintegrate in Earth’s atmosphere, probably resulting in only a handful of small meteorites.
Amateur astronomer Gennadiy Borisov just discovered it on January 21 at an observatory in Crimea2023 THISasteroid. NASA’s impact risk assessment system quickly determined that the asteroid would not hit Earth.
“Despite the very small number of observations, it was predicted that this asteroid will come very close to Earth,” said Davide Farnocchia, a NASA expert who helped develop the assessment system.
“In fact, this is one of the closest known near-Earth objects to Earth on record.”
The asteroid’s close proximity to Earth would cause its orbit around the sun to change significantly. NASA said that in the past, it took 359 days for an asteroid to orbit the sun, but this time it will take 425 days after it approaches the earth.
