Asteroid 2004 MN4 is a near-Earth asteroid that was discovered on June 19, 2004. It is notable for its close approach to Earth, with a minimum distance of about 38,000 kilometers (24,000 miles) predicted for April 13, 2029. This proximity raised initial concerns about a potential impact, but further observations have significantly reduced the risk. The asteroid is approximately 320 meters (1,050 feet) in diameter and is classified as a member of the Apollo group of asteroids. Its orbit takes it around the Sun, and it completes a full orbit approximately every 1.3 years.
