Asteroid 99942 Apophis is set to make a dramatic pass by Earth in April 2029, giving scientists and skywatchers a rare look at a large near-Earth object from relatively close range. Current expectations are that Apophis will miss Earth, but the event is still drawing intense attention because of how unusual and important such a flyby can be.
Apophis is described as a space rock about 370 meters, or roughly 1,210 feet, across. An asteroid of that size passing so near Earth is not a routine event, which is why researchers are already focusing on its path through near-Earth space and what can be learned as it approaches.
The concern highlighted by scientists is not that Apophis is expected to strike the planet in 2029, but that a very close encounter can still have significant consequences. A pass like this can raise important questions about the asteroid’s motion, how it behaves during a close approach, and what the event could mean for future monitoring of potentially hazardous objects.
Because Apophis will come so close without hitting Earth, the 2029 flyby is shaping up to be a major moment for asteroid science. It offers a rare chance to study a large object up close while also reminding researchers why tracking near-Earth asteroids remains a serious part of planetary defense work.
