# Near‑Earth asteroid close approaches 2026‑2029 > Live situation record from CLSTR: https://clstr.news/situations/2026-close-approach-of-asteroid-152637 > Updated: 2026-08-06T17:49:04.000Z. Sources: 107. Developments: 16. The Aten‑class asteroid (152637) 1997 NC1 safely passed Earth on 27 June 2026 at about 2.56 million km, with radar and optical tracking confirming zero impact risk and refining its size to 750 m–1.6 km. The event coincided with International Asteroid Day and spurred worldwide observation campaigns. The headline encounter on 13 April 2029 will bring the 340‑m stony asteroid 99942 Apophis within roughly 32 000 km of Earth—well inside the geostationary belt and visible to most of the global population. NASA’s OSIRIS‑APEX, ESA’s RAMSES, JAXA’s DESTINY+ and a Chinese student CubeSat are being prepared to study Apophis’s spin, surface and gravitational response. Recent modeling highlighted that fragments of space debris in geostationary orbit could intersect Apophis’s path, potentially compromising observations. Italian researchers Giulia Schettino and Alessandro Rossi warned of a small but real collision risk that could affect data from the planned missions. OSIRIS‑APEX will monitor any debris‑interaction hazards, providing data for the 2029 flyby and the subsequent 2036 approach. NASA and ESA have now formally ruled out any impact threat from Apophis for at least the next century, confirming earlier assessments. The agencies emphasize that the close approach offers a rare opportunity for planetary‑science studies while underscoring the growing concern over orbital debris. ## Claims - Apophis will pass within about 32,000 km of Earth on 13 April 2029. (corroborated by 4 sources) - The fly‑by distance is lower than the altitude of geostationary satellites (~35,800 km). (corroborated by 4 sources) - NASA and ESA have ruled out any impact risk from Apophis for at least the next century. (corroborated by 4 sources) - The close approach will let scientists study Earth’s gravitational effects on Apophis, including changes to its orbit and rotation. (corroborated by 4 sources) - NASA’s OSIRIS‑APEX mission and ESA’s RAMSES mission are planned to observe Apophis during the encounter. (corroborated by 4 sources) - Apophis is about 340 metres in diameter. (corroborated by 4 sources) - Simulations indicate a small risk that Apophis could collide with human‑made space debris during its 2029 pass.
