Summary
Visibility maps presented in June 2026 estimate up to 7.6 billion people—nearly 90% of humanity—could potentially see asteroid Apophis during its safe 13 April 2029 flyby.
The estimate tracks the cumulative viewing footprint over roughly seven hours, not a single shared view: Australia, Asia, Africa, Europe and parts of eastern South America rotate into favorable geometry at different times, while North America is poorly placed.
At peak brightness around 20:35 UTC, Apophis should shine near magnitude 2.8 and move visibly against the stars; closest approach, about 32,000 kilometers above Earth’s surface, follows roughly an hour later.
Cloud, haze, city lights and blocked horizons will sharply reduce the real audience, and the 90% figure reflects access in principle rather than likely participation.
NASA and ESA have ruled out any Apophis impact for at least 100 years, with 2021 radar observations tightening its orbit enough to support both the safety assessment and detailed viewing maps.
We know Apophis will safely miss Earth in 2029, but how exactly will our planet's gravitational tug rewrite the asteroid's future trajectory?
As Earth's gravity physically alters Apophis in 2029, what hidden secrets will the approaching RAMSES spacecraft uncover from its freshly exposed surface?
With 90 percent of humanity under its path, could this unprecedented naked-eye asteroid flyby trigger a massive shift in global planetary defense?
