Apophis: Naked-eye near-Earth visitor set for a historic 2029 pass

NASA says the 1,230-foot asteroid Apophis, nicknamed the God of chaos, will skim past Earth in 2029 at about 20,000 miles (roughly 32,000 kilometers) away — closer than many satellites and potentially visible to the naked eye in the Eastern Hemisphere if weather cooperates. There is no risk to Earth, and radar observations have ruled out impact for at least a century. ESA plans to deploy the Rapid Apophis Mission to study its gravity-induced effects, and Apophis will return in 2036 at a much safer distance.

The 1883 near-miss that almost escaped history

Mexico’s 1883 observations by astronomer José Bonilla showed 447 objects crossing the Sun over about three hours, later reinterpreted as a highly fragmented comet passing unusually close to Earth. New analysis suggests the debris may have been within roughly 80,000 km of Earth, with fragments potentially 50–800 meters across—a Tunguska-like threat that went largely unnoticed due to geography and limited coverage at the time. Bonilla’s work was initially dismissed, but subsequent research revived the idea of a historic near-miss with dramatic potential if the debris had been closer.

"NASA Reports 310-Foot Asteroid to Whiz by Earth: Details on Speed and Proximity"

NASA's Center for Near-Earth Object Studies (CNEOS) has tracked Asteroid 2019 KK5, a 310-foot Near-Earth Asteroid, which is set to pass Earth at a distance of 4 million kilometers today at a speed of 75,328 kilometers per hour. Although it's classified as a Near-Earth Asteroid, it is not considered potentially hazardous as it does not meet the size and proximity criteria. This Apollo group asteroid, which is not expected to impact Earth, has passed by our planet before and is not predicted to do so again in the near future.
