As calculations show, a large asteroid reached its closest distance to Earth on Tuesday, January 18 (Wednesday, January 29) and was completely safe from the planet. We passed.

In this transition, asteroid 7482 (1994 PC1), which is classified as an asteroid close to Earth, was only five times the distance of the moon from our planet, about 1.6 million kilometers. Such a close distance between the Earth and the asteroid will not occur for the next two centuries. Watch this crime with a width of 1 km in the nearest part of its passage, which occurred at 16:51 in the Eastern time zone (01:21 in the morning, Tehran time). The asteroid was discovered from the Apollo asteroids group on August 9, 1994, and its orbit is now well known. Defined. According to NASA, some of these objects, located at a distance of 1.3 astronomical units (about 194.5 million kilometers) from Earth, are classified as a "Newar Earth Object" or NEO. It is worth mentioning that each astronomical unit is equal to the average distance between the Earth and the Sun and is about 150 million kilometers.

There is no known crime that could pose an immediate threat to Earth, NASA keeps its eyes open. With the help of its ground and space telescopes and international partners, the agency monitors and hunts near-Earth objects while assessing potential hazards through the Planetary Defense Coordination Office.

  • See asteroids live near Earth with NASA's eyes

NASA is also testing possible planet defense technology; Including the "Double asteroid Redirection Test" or "DART", which was launched a few months ago and intends to change the path of an asteroid in the fall of 2022 with a severe collision.

On a larger scale, NASA is tasked by Congress with mapping and reporting at least 90 percent of all near-Earth objects 140 meters wide and larger, including asteroid 7482 (1994 PC1). The agency was tasked with completing the mapping by 2020, but failed to meet that deadline. Is set to be launched in 2026 to complete the exploration in 10 years. Project
