The massive 1.8-kilometer asteroid will meet Earth this week

According to NASA, a massive asteroid with a diameter of about 1.8 km will approach Earth on May 27 (June 6). However, NASA's Center for Near-Earth Object Studies (CNEOS) emphasizes that there is nothing to worry about, and even at its closest passage, the asteroid, named 7335 (JA 1989), is approximately 4 million kilometers, about 10 times the average distance between The Earth and the Moon will be far away from us.

But given the huge size of this space rock at 1.8 km and the relatively short distance to Earth from a cosmic point of view, NASA calls the asteroid "potentially dangerous." Has been classified, meaning that it could cause a lot of damage to our planet if it deviates from orbit and collides with Earth. But according to NASA, 7335 (1989 JA) is the largest asteroid to approach Earth in 2022. Scientists estimate that the asteroid will travel at a speed of about 76,000 kilometers per hour, or 20 times faster than a high-velocity bullet. And then it will pass even farther from near this year and about 70 times the distance between the Earth and the moon. The American astronomer Eleanor F. Helin discovered the asteroid on May 1, 1989.

This asteroid is one of more than 29,000 "near-Earth objects" (NEO ) That NASA tracks every year. According to NASA, NEO is any astronomical object that travels less than 48 million kilometers from Earth. Most of these objects are very small, but 73335 (1989 JA) is larger than about 99% of near-Earth objects. This class refers to asteroids that periodically intersect with Earth's orbits in their orbits around the Sun and meet our planet. Astronomers have identified about 15,000 such asteroids.

NASA is closely monitoring NEOs like this and recently launched a mission to test whether potentially dangerous asteroids could one day deviate from Earth.

In November 2021, the space agency launched a dual asteroid reversal experiment, or DART, which landed in the fall of 2022 with the 160-meter asteroid Dimorphos. , The asteroid moon Didimus will collide. This collision could slightly change the asteroid's path.
