A large asteroid measuring 1 km in width has recently been reported to have passed close to Earth.

Although it was impossible to see the asteroid with the naked eye, experts say it could be seen with a small astronomical telescope.

According to Now News, the National Aeronautics and Space Administration (NASA) announced that asteroid 7482 (1994 PC1) was traveling at a speed of about 76,000 km/h at 4:51 pm eastern time on the 18th (around 6:50 am Korean time on the 19th). It said that it passed through space at a speed of 1.92 million kilometers from the Earth’s surface.

This corresponds to 5.15 times the 383,000 km distance between the Earth and the Moon, and there was no possibility of a collision with the Earth.

The image of the asteroid was photographed and released by Gianluca Marci, a physicist at the Bellatrix Observatory in Italy. An image taken through a terrestrial telescope shows asteroid 7482 (1994 PC1), marked by bright white dots, and several stars moving around it.

Dr. Marsh also released a video made by putting the photos together. “We were able to take several images of the asteroid as it ‘safely’ approached Earth,” he said. did.

Asteroid 7482 (1994 PC1) has a brightness of about 10 degrees, and in some areas of the Earth, such as Italy, it was possible to see the passing of the asteroid using a ground telescope. The next time the asteroid passes close to Earth is 2105.

This asteroid is not the largest asteroid that has ever passed Earth. 3122 Florence (1981 ET3), which moved away from Earth on October 1, 2017 (Eastern Time in the United States), was observed to reach a width of 4 to 8.8 km. The asteroid will pass Earth again on October 2, 2057.

NASA says it is unlikely that an asteroid larger than 140 meters in size will collide with Earth within 100 years.

However, he added that active preparation for the future is necessary as only about 16% of near-Earth asteroids with a size of 100 to 300 m have been discovered so far.

NASA is conducting the ‘Double Asteroid Orbital Correction Test (DART)’ with experts from various countries, including Korea. This is part of the Earth’s defense strategy to prevent asteroid impact disasters such as the mass extinction of the dinosaurs 66 million years ago.

NASA’s DART spacecraft was launched on October 21 last year, and in September of this year, it could change the orbital time by colliding with an asteroid the size of a football stadium ‘Dimorphos’ orbiting the near-Earth asteroid ‘Didymos’. will experiment
