Asteroid 1999 AN10 is a near-Earth asteroid that was discovered on January 13, 1999. It belongs to the Apollo group of asteroids, which are known for their orbits that cross Earth's path. This asteroid has an estimated diameter of about 1.1 kilometers and is classified as a potentially hazardous object due to its size and proximity to Earth. The asteroid's orbit brings it close to our planet approximately every 7.5 years. Its next close approach is expected in 2027, when it will pass within about 380,000 kilometers of Earth. Scientists monitor such asteroids to assess any potential impact risks and to better understand their characteristics.
