The asteroid with a diameter of at least 580 m, which has flown closest to Earth over the past 4 centuries, will pass by our planet on February 16 but poses no danger.

Asteroid 2005 YY128 will fly 4.5 million miles from Earth at 7:46 a.m. on Feb. 16, the closest it has been in more than 400 years, according to EarthSky. org. However, this distance is still 12 times greater than the distance between the Earth and the Moon, so This asteroid is unlikely to hit Earth.
As its name suggests, 2005 YY128 was discovered in 2005 by astronomers from Kitt Peak Observatory in southern Arizona. Over the past 17 years, the team has mapped its orbit with great precision. However, their observations were unable to accurately determine the size of 2005 YY128. Instead, they can only estimate its diameter to be between 580 and 1,300 m.
SO, 2005 YY128 is in the category of potentially hazardous asteroids (PHA), Includes meteorites that are at least 140 m wide and whose orbits are within 0.05 astronomical units of Earth (AU is the average distance between the Earth and the Sun, equivalent to 150 million km , so 0.05 AU is approximately 7.4 million km). If it crashes into Earth, the 2005 YY128 will cause serious damage.
According to the non-profit organization Global Challenges Foundation, the largest near-Earth asteroids (NEOs) are capable of affecting geology and climate on a global scale, disrupting human civilization and potentially leading to the extinction of many species. Smaller near-Earth objects, located between 140 and 1,000 m, could cause regional or continental damage, causing hundreds of millions of deaths.
10 years ago, on February 15, 2013, a 20 m wide meteorite exploded in the sky over the city of Chelyabinsk in Russia, shattering thousands of windows and injuring several people on the ground. NASA opened the Planetary Defense Coordination Office a few years later Event in Chelyabinsk. Astronomers and researchers around the world are joining the fight to protect Earth. NASA and its partners have discovered more than 95 percent of asteroids at least a kilometer wide that could pass Earth within a 50 million kilometer radius, but none posed a danger in the near future.
