Near-Earth Rock Slips Through Detection Door Before Close Flyby

Near-Earth Rock Slips Through Detection Door Before Close Flyby

An asteroid the size of a blue whale will pass about 56,500 miles from Earth tonight (roughly 24% of the Earth–Moon distance), but it wasn’t discovered until roughly a week ago because key radar facilities are down after Arecibo’s collapse and ongoing Goldstone repairs; only about 1% of Earth-skimming asteroids this size get flagged, even as surveys like Vera Rubin Observatory discover thousands of new objects, highlighting gaps in our planetary defense.

Basketball-court-sized asteroid to skim Earth tonight, watch via livestream

An asteroid the size of a basketball court, designated 2026 JH2, will pass closer to Earth than the Moon this evening and will be visible with small telescopes from the Northern Hemisphere, though it’ll be low in the sky after sunset; there’s no danger, and the Virtual Telescope Project will stream the closest approach starting at 19:45 UTC.

62-foot asteroid to skim Earth closer than the Moon

An approximately 62-foot asteroid named 2026 JH2 will pass about 57,000 miles from Earth—closer than the Moon—around 6 p.m. ET Monday. It was discovered May 10 by the Mount Lemmon Survey and may be visible with small telescopes, but it poses no threat to Earth. NASA/ESA are tracking the flyby, and the Virtual Telescope Project will stream it online. The article also notes a much larger asteroid, Apophis, approaching Earth in 2029 and mentions the OSIRIS-APEX mission and potential budget cuts affecting NASA’s plans.

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

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.

Apophis to skim past Earth in 2029, NASA confirms

The near‑Earth asteroid 99942 Apophis, about 375 meters across, will pass roughly 20,000 miles (about 32,000 km) above Earth on April 13, 2029—close enough to be seen with the naked eye from the Eastern Hemisphere—with radar data eliminating any collision risk for at least a century. NASA’s OSIRIS‑APEX mission will study the gravitational and surface effects during the encounter, while ESA’s Ramses will observe the flyby to improve our understanding of asteroid composition and internal structure, a rare event that helps refine planetary defense models.

Car-sized asteroid to skim Earth tonight at about half the Moon's distance

Car-sized asteroid to skim Earth tonight at about half the Moon's distance

A car-sized near-Earth asteroid named 2026 FM3, discovered days ago by the Zwicky Transient Facility at Palomar, will pass by Earth tonight at roughly 237,918 km (about 0.618 lunar distances) at ~11,461 mph. The flyby is timed for 10:07 p.m. EDT (02:07 GMT) and the object will also miss the Moon a few hours later, at about 595,492 km. With an estimated diameter of 4–8 meters, it poses no risk to Earth or the Moon, and NASA expects no close approaches for the next century. The event highlights how upcoming observatories will keep finding many more near-Earth objects.)

JWST refines 2024 YR4’s path, lunar impact odds drop to zero

JWST refines 2024 YR4’s path, lunar impact odds drop to zero

NASA’s James Webb Space Telescope refined the trajectory of near-Earth asteroid 2024 YR4, eliminating the possibility it will hit the Moon and lowering the lunar‑impact probability from about 4.3% to zero. The asteroid will pass by the Moon at roughly 13,200 miles (21,200 km) from the lunar surface in 2032, while Earth remains safely distant. The rock is estimated at 53–67 meters in diameter, and JWST’s observations—among the faintest ever of an asteroid—pushed the telescope to its limits. NASA plans another JWST look at 2024 YR4 in 2028.
