rekordy: List of asteroid close approaches to Earth

In 2014, scientists estimated that several dozen asteroids in the 6–12 m (20–39 ft) size range fly by Earth at a distance closer than the Moon every year, but only a fraction of these are actually detected.

This is a list of examples where an asteroid or meteoroid travels close to the Earth. Some of these objects are regarded as potentially hazardous objects if they are estimated to be large enough to cause regional devastation. This list also gives an overview of more detailed lists dedicated to specific years, such as List of asteroid close approaches to Earth in 2025. Near-Earth object detection technology began to improve around 1998, so objects being detected as of 2004 could have been missed only a decade earlier due to a lack of dedicated near-Earth astronomical surveys. As sky surveys improve, smaller and smaller asteroids are regularly being discovered. As smaller asteroids are more numerous, ever more close approaches are detected within a given distance. In 2014, scientists estimated that several dozen asteroids in the 6–12 m (20–39 ft) size range fly by Earth at a distance closer than the Moon every year, but only a fraction of these are actually detected.
