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.

DART Achieves First Solar-Orbit Change After Asteroid Impact

NASA’s DART mission confirmed that crashing into the small asteroid Dimorphos shortened its orbit around the larger Didymos by about 32 minutes, and new analysis shows the impact also nudged the binary system’s solar trajectory by roughly 1.7 inches (4.3 cm) per hour—the first measured change in an object’s path around the Sun—demonstrating humanity’s ability to steer asteroids if needed.

DART’s hit nudged the Didymos–Dimorphos pair into a slightly faster solar orbit

NASA’s DART spacecraft’s impact on Dimorphos altered the binary asteroid system’s motion around the Sun: their orbital period around the Sun shortened by about 0.15 seconds (from ~770 days) due to momentum transfer and debris ejection (~16 million kg). The measured change in orbital speed was ~11.7 microns per second, marking the first time a human-made object subtly altered a celestial body’s solar orbit; follow-up Hera observations will study the aftermath.

DART makes history by nudging an asteroid's path around the Sun

NASA's DART spacecraft’s 2022 impact on Dimorphos not only shortened the moonlet's orbit around Didymos but also measurably altered the Didymos–Dimorphos system's orbit around the Sun, changing the pair's solar trajectory by about 11.7 microns per second (roughly 1.7 inches per hour). This first-of-its-kind result supports planetary-defense research by showing how small nudges can accumulate to influence long-term hazard assessments.
