";s:4:"text";s:3615:"From the list in the first section, these are the closest-known asteroids per year that approach Earth within one lunar distance.More than one asteroid per year may be listed if its geocentric distance is within a tenth of the lunar distance, or 0.10 LD. Spooky Halloween asteroid flyby one of the closest near misses ever seen A big space boulder scopes out the trick-or-treating situation here on Earth. The distance of the asteroid to Earth was roughly 42,735km (26,554 miles), putting it at risk of potentially colliding with a comms satellite (from the European Data Relay System). In February 2011, a relatively small asteroid made big news when it whizzed by the Earth. It is the closest an asteroid has ever been to the planet without making landfall. A list of known near-Earth asteroid close approaches less than 1 lunar distance (0.0025696 AU (384,410 km; 238,860 mi)) from Earth in 2018.. For reference, the radius of Earth is approximately 0.0000426 AU (6,370 km; 3,960 mi) or 0.0166 lunar distances. An asteroid between 16 and 34 meters in diameter (36 and 112 feet) flew by the Earth om 7th January morning, about twice as close to our home planet as the moon. It was a bit of a surprise for scientists, who weren't even aware of its existence until it was spotted just 14 hours before it passed by. It was a harmless flyby for the record books. 2019 has been a notable year in that an asteroid was detected prior to impact ().This has only happened three times previously (see List of successfully predicted asteroid impacts).

Fortunately, it doesn't knock on any doors. A decade from now, on April 15, 2029, an asteroid will swing past the Earth, just barely missing everything.The asteroid—nicknamed Apophis—will be as close …
