Apophis 2029 flyby could spark a naked-eye sky show for billions

Asteroid Apophis, about 375 meters across, will pass roughly 32,000 km from Earth on 13 April 2029 and could be visible to the naked eye for up to seven hours across a cumulative viewing region that may cover up to about 7.6 billion people; peak brightness is around magnitude 2.8, though actual visibility depends on darkness, weather and light pollution. The flyby is deemed safe, and radar data from 2021 refined the orbit to remove any impact risk for at least a century.

Asteroid Apophis to skim by Earth in 2029 as NASA’s OSIRIS-APEX trails to study gravity’s effect

In April 2029, asteroid 99942 Apophis will pass about 32,000 km above Earth — closer than geostationary satellites — and NASA’s OSIRIS-APEX will watch from afar and then trail the asteroid to map how Earth’s gravity changes its orbit, rotation and surface. The mission will use cameras, spectrometers and a laser altimeter to characterize Apophis’s shape and composition, with a close ground-proximity pass later used to study surface changes, while Earth provides a well-understood gravitational test for a potentially hazardous, rubble-pile body.

Apophis 2029 Flyby Could Be Obscured by Space Debris, Scientists Warn

Asteroid 99942 Apophis (about 370 meters long) will pass within ~32,000 kilometers of Earth in April 2029. New simulations indicate a collision with high-Earth-orbit space debris could occur, which would not significantly alter Apophis's orbit but could complicate interpreting gravity-driven changes during the flyby. The possibility underscores gaps in debris surveys and could spur improved monitoring ahead of the encounter, with ESA's RAMSES and NASA–ESA OSIRIS-APEX observations planned.

Apophis 2029 Flyby Could Be Complicated by Space Debris

Astronomers say asteroid 99942 Apophis will skim Earth in April 2029 at roughly 32,000 km distance. While a direct hit remains unlikely, a new study finds a small chance that debris in geostationary orbit could collide with Apophis, potentially muddying the interpretation of the flyby data. ESA’s RAMSES and NASA’s OSIRIS-APEX will observe the event, and any collision would likely produce a small crater and ejecta without significantly altering the asteroid’s trajectory. The work also highlights gaps in our knowledge of high-Earth-orbit debris and calls for improved surveillance before 2029.

Apophis 2029 Flyby: Billions Could Witness a Close Naked-Eye Earth Pass

On 13 April 2029, asteroid 99942 Apophis will pass about 32,000 km from Earth—closer than geostationary satellites—offering a rare, world-spanning viewing event, though NASA says there is no impact risk for at least a century. New visibility maps suggest as many as 7.6 billion people could see it with the naked eye during roughly seven hours, depending on darkness and sky conditions. Scientists will study the encounter to learn about asteroid structure and gravity effects, while three spacecraft programs—ESA’s Ramses, JAXA’s DESTINY+, and NASA’s OSIRIS-APEX—will observe Apophis before, during and after the flyby as a planetary-defense rehearsal.

Apophis: A naked-eye 2029 flyby set to beam across billions of skies

New maps project the potentially hazardous asteroid Apophis will perform a seven‑hour, ultra‑close flyby on April 13, 2029, passing about 19,000 miles from Earth and could be visible to up to 90% of the world’s population. At the start, as many as ~4.5 billion people might see it; peak visibility could reach ~5.7 billion across eastern Africa, Southern Europe, Australia, Asia and the Middle East; by the end, ~1.9 billion in eastern South America, northern Africa and parts of Europe. North America is expected to miss the clear view. It will appear as a modest, slow‑moving star, and there is zero chance of impact in the next 100 years, though the trajectory could shift slightly. Scientists will coordinate global observations, with missions like NASA’s OSIRIS‑APEX studying its structure; the event coincides with the UN’s International Year of Asteroid Awareness and Planetary Defence.

Apophis 2029: Naked-eye asteroid flyby that will skim Earth

A 375-meter asteroid named Apophis will pass about 31,600 kilometers from Earth on 13 April 2029, closer than geostationary satellites and bright enough to be seen with the naked eye by up to two billion people across Europe, Africa and western Asia. It's a safe flyby with no collision risk for at least a century, and space agencies plan missions OSIRIS-APEX and Ramses to study the encounter and improve understanding of asteroid structure and planetary defence.

Apophis 2029: a global naked-eye sky show with a safe flyby

Astronomers predict the near‑Earth asteroid 99942 Apophis will pass by Earth on April 13, 2029, and be visible to the naked eye for about seven hours as it travels from Australia to the North Atlantic; at closest approach it will be roughly 19,700 miles above Earth and should be brightest near Cameroon. NASA says there is no impact risk for 2029 or the next century, making this a safe, rare opportunity to study how Earth's gravity affects an asteroid—potentially triggering landslides or exposing pristine material, though the exact outcome is unknown. Visibility depends on weather and light pollution, but estimates suggest billions could see it in principle.

ESA and JAXA Seal Ramses Collaboration to Study Apophis Before the 2029 Flyby

The European Space Agency and the Japan Aerospace Exploration Agency have formalized a Ramses collaboration to study asteroid Apophis during its 2029 Earth flyby: Ramses is set to launch in 2028 on an H3 rocket, with JAXA supplying solar arrays and a thermal infrared imager and OHB Italia as prime contractor. The mission would reach Apophis in February 2029, about two months before its close approach to Earth at roughly 32,000 kilometers, enabling detailed observations of the asteroid’s surface and the flyby’s gravitational effects for science and planetary defense insights.

ESA and JAXA Unite on Ramses: A Historic Mission to Study Apophis and Boost Planetary Defense

ESA and JAXA signed an agreement to launch the Ramses mission to the near-Earth asteroid Apophis, with a planned 2028 launch and a 2029 rendezvous during its close Earth flyby at about 32,000 km. The mission aims to study how Apophis behaves under Earth's gravity and to collect data that could improve asteroid deflection and monitoring strategies, informing future planetary-defense efforts. ESA will lead spacecraft design and operations, JAXA will contribute lightweight solar arrays and an infrared imager, and ESA’s NEO Coordination Centre will refine orbital predictions ahead of the flyby. This collaboration showcases international partnership as a cornerstone of global space safety.”,

Global pact for planetary defence as Ramses targets Apophis

ESA and JAXA signed memoranda to deepen planetary-defence collaboration and advance the Ramses mission to rendezvous with asteroid Apophis ahead of its 2029 Earth flyby, with ESA leading spacecraft design and JAXA contributing key hardware to study tidal effects and improve deflection knowledge; the 2029 flyby will bring Apophis within about 32,000 km of Earth, presenting a rare science and public-engagement opportunity.

Apophis to zip by Earth in 2029, a near-light-speed shift in its orbit

NASA says the Eiffel Tower–sized asteroid Apophis, categorized as potentially hazardous, will pass Earth in April 2029 at about 20,000 miles away—closer than many geosynchronous satellites—nudging its orbit and rotation but posing no immediate risk. Discovered in 2004, Apophis is a remnant from the solar system’s formation; its name comes from the Egyptian god of chaos. Astronomers plan close-up observations, aided by missions like OSIRIS‑REx and Ramses to study the encounter.

Apophis 2029 Flyby: Naked-Eye Close Encounter Near Earth

NASA says the 1,230-foot asteroid Apophis, nicknamed the God of Chaos, will skim within about 20,000 miles of Earth in 2029—closer than many satellites and bright enough to be seen with the naked eye—providing a historic opportunity for observation and planetary-defense research; there is no threat to Earth, and the asteroid will return in 2036 much farther away.
