On March 15, 2004, a near-Earth asteroid was discovered by the NASA-funded LINEAR asteroid survey. The asteroid, called 2004 FH, is approximately 30 meters in diameter. On March 18, 2004, it passed about 26,000 miles above Earth's surface. This made it the fourth closest approach to Earth recorded.
Had 2004 FH hit Earth, it would have probably detonated high in the atmosphere. It might have produced a blast measured in hundreds of kilotons of TNT. It probably would not have produced any ground level effect. Despite its relatively small size, it is still the third largest asteroid found coming closer to Earth than the moon. The asteroid will not make another close approach to Earth until 2044.
