An asteroid with a diameter of about 50m is approaching the earth, and the collision probability is estimated to be about 1 in 625

It is reported that the asteroid ` ` 2023 DW '' with a diameter of about 165 feet (about 50 m) discovered on February 27, 2023 may approach the earth in February 2046. The odds of an asteroid hitting the Earth are estimated to be about 1 in 625, making it extremely unlikely that an asteroid will impact the Earth.

2023 DW was the first asteroid observed on February 27, 2023. According to the European Space Agency (ESA), 2023 DW is about 165 feet in diameter and will be the closest to Earth on February 14, 2046. The probability of approaching and colliding with the earth is estimated to be about 1/625 at the time of article creation . Although this collision probability is higher than the average of near-Earth planets, NASA states that ``the possibility of colliding with the Earth is very low'', and it is possible that more accurate observation of asteroids will become possible. is expected to decline.

In a tweet reporting that NASA is tracking 2023 DW, it said, 'Often, when we first discover a new object, we don't have enough data to properly predict its orbit several years into the future. is needed,” he said.

According to the scientific news media Livescience, it is not predicted at this stage that even if 2023 DW collides with the earth, it will cause catastrophic damage to humanity. However, if 2023 DW were to fall on Earth's major cities or densely populated areas, it could cause severe local damage. In 2013, the size of the meteorite that fell over Chelyabinsk, Russia, ranged from a few meters to 15 meters, less than half the size of the 2023 DW, but it injured about 1,500 people and injured about 4,500 people. The building structure was damaged.

In addition, NASA is researching a method to change the orbit of an asteroid, and in 2022 announced that it was successful in conducting an experiment called ' Double Asteroid Redirection Test ' to change the course by colliding the spacecraft with the asteroid. I'm here.

``We will continue to monitor asteroid 2023 DW and will update our predictions as more data comes in,'' NASA said.
