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.

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.

China Plans Mach 26 Asteroid-Deflection Test to Protect Earth

China's CNSA outlines a two-spacecraft, Mach-26 asteroid-deflection test scheduled for a 2029–2030 Earth-close approach, targeting near-Earth asteroid 2015 XF261 (~30 meters) and altering its trajectory relative to Earth. One craft would strike the asteroid while a second observes its orbit, shape, and surface both before and after impact. The mission would launch the two spacecraft together and aims to provide a more realistic planetary-defense scenario than NASA's DART, which changed Dimorphos’ orbit by about 33 minutes and used follow-on observations from LICIACube and Hera.

Hayabusa2 photographs Torifune on a distant, high‑speed flyby

Japan’s Hayabusa2 spacecraft conducted a high‑speed flyby of asteroid Torifune about 62 million miles from Earth, capturing optical imagery with its ONC‑T camera and thermal data with the Mid‑Infrared Camera to analyze surface temperatures and roughness. The encounter, not part of the original mission and described as risky, adds to Hayabusa2’s long-running exploration after returning Ryugu’s samples in 2020 and sets the stage for its future target 1998 KY26 in 2031 while showcasing the probe’s ongoing study of small solar‑system bodies.

Blue-whale-sized asteroid to skim Earth via May livestream

A newly discovered near-Earth asteroid, 2026 JH2, estimated at 16–35 meters, will pass Earth on May 18 at about 91,000 km (roughly 0.23 lunar distances). The Virtual Telescope Project will stream the close approach live on YouTube starting at 3:45 p.m. EDT, weather permitting; the flyby poses no threat to Earth.

Basketball-court-sized asteroid to skim past Earth closer than the Moon

A 16–35 metre near-Earth asteroid named 2026 JH2 will pass about 90,000 km from Earth on May 18, 2026—roughly a quarter of the Earth–Moon distance— posing no danger and may be visible with a small telescope (mag ~11.5). It was discovered May 10 by the Mt. Lemmon Survey and will be tracked with a livestream by the Virtual Telescope project.

Newly Found Asteroid 2026 JH2 Set for One of This Year's Tightest Earth Approaches

Astronomers have identified near-Earth asteroid 2026 JH2, which will make one of this year's closest flybys, passing within about 0.00058–0.00064 AU of Earth (roughly 90,000 km) after an initial Moon approach on May 18, 2026; there is no expected danger, it may be visible with modest amateur telescopes, and a livestream of observations is planned.

Apophis to skim Earth in 2029, unlocking new asteroid science

Earth’s giant near-Earth asteroid Apophis, about a quarter-mile long, will pass within about 20,000 miles of Earth on April 13, 2029—the closest approach of a large known asteroid—offering a rare chance to study its surface and motion as NASA and ESA prepare dedicated observations (OSIRIS-APEX and Ramses) while the initial risk of impact has been ruled out for at least a century.

Apophis 2029: Close-Range Flyby Opens a Scientific Window

NASA says Apophis, a roughly 1,100‑foot-wide near‑Earth asteroid nicknamed the 'god of chaos,' will pass about 20,000 miles from Earth on April 13, 2029—an exceptionally close flyby that offers a rare opportunity to study a space rock with modern technology. The agency notes no collision risk for at least 100 years, though Earth's gravity could cause minor surface movement, helping scientists learn about its composition. Observers in the Eastern Hemisphere may glimpse it if weather permits.

House-sized asteroid to skim Earth tonight, no danger expected

A 16-meter asteroid named 2026 GD will pass Earth tonight at about 0.65 lunar distances (roughly 156,000 miles) and then come within about 101,000 miles of the Moon later that evening, posing no threat to Earth or the Moon; it is on the ESA Risk List but carries an extremely small cumulative impact probability, and it won’t affect the Artemis 2 mission; the asteroid will continue on a long orbit with a next close approach expected around July 2031 near Venus.

Bus-Size Asteroid Flies By Earth, No Threat Confirmed by NASA

NASA tracked a roughly 140-foot asteroid, 2007 EG, as it passed about 1.06 million miles (roughly 1.7 million kilometers) from Earth on March 15, 2026. There was no threat detected, and it was part of routine planetary-defense monitoring of thousands of near-Earth objects. The asteroid’s Aten-class orbit crosses Earth’s path, and future close approaches are predicted, including in 2028 and 2043, with ongoing observations to refine its trajectory. ISRO plans to participate more in international asteroid missions.

Bus-sized asteroid 2026 EG1 to skim past Earth in a near-miss

A newly discovered bus-sized asteroid named 2026 EG1, about 10–22 meters across, will pass within about 1 lunar distance of Earth late on March 12 (closest approach around 11:27 p.m. EDT / 0327 GMT March 13), traveling at roughly 21,513 mph. Discovered March 8, it poses no threat; NASA tracks thousands of near-Earth objects and continues defense planning with help from observatories like Vera Rubin.

"Live: Watch Airplane-Size Asteroid's Close Encounter with Earth and Moon Today"

Astronomers discovered asteroid 2024 BJ earlier this month, and it will pass between Earth and the moon on January 27. The 121-foot-wide space rock will fly by Earth at a distance closer than the moon, reaching its closest point at 12:30 p.m. EST. The Virtual Telescope Project will livestream the event, and the asteroid is not considered hazardous. Scientists have plans in place to deal with potential Earth-threatening asteroids, but such a scenario is not expected in the next 1,000 years.
