Asteroid discovered hours before impacting Earth 


Similar asteroid impact in 1999

Hungarian astronomer Krisztián Sárneczky at the Piszkésteto Mountain Station – part of Konkoly Observatory near Budapest – discovered a small asteroid on March 11, 2022, just two hours before it struck Earth’s atmosphere. The asteroid is believed to have started out about 10 feet (3 meters) wide. Now labeled 2022 EB5, this object entered Earth’s atmosphere north of Iceland at 21:22 UTC on March 11…

The asteroid is estimated to have been moving at a speed of about 11 miles per second (18.5 km/s). That’s in contrast to Earth’s own speed in orbit of 18 miles per second (30 km/s). Its flight through our atmosphere would have caused all or part of this small asteroid to vaporize due to friction with the air. So its headlong flight through our atmosphere should have caused a bright meteor, or shooting star, often called a fireball.

The International Meteor Organization is seeking reports of anyone who might have seen the brilliant meteor created by 2022 EB5. A few people in Iceland reported seeing a bright flash of light, or hearing a boom. If you live around Iceland and Norway and believe you saw the resulting meteor from this asteroid impact with Earth, click this link to report your observations.

Pretty likely this asteroid didn’t survive Earth’s atmosphere to impact the planet surface. At least. no record of a meteorite, yet. Still, RTFA. Radar and telescope tracking images are interesting.

    “An international team of astronomers has discovered three new near-Earth asteroids (NEAs) hiding in the inner Solar System, the region interior to the orbits of Earth and Venus. Due to the intense glare of the sun, this is a notoriously challenging region for asteroid hunters to make observations. The detections were possible due to observations using the Dark Energy Camera (DECam) mounted on the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile, a Program of NSF’s NOIRLab.
    However, the astronomers uncovered an elusive trio of NEAs by taking advantage of the brief yet favorable observing conditions during twilight. One of the NEAs is a 1.5-kilometer-wide (0.9-mile-wide) asteroid called 2022 AP7. It has an orbit that may place it in Earth’s path at some point in the future. Fortunately, the other asteroids, designated 2021 LJ4 and 2021 PH27, have orbits that safely remain completely interior to Earth’s orbit. Also of special interest to astronomers and astrophysicists, 2021 PH27 is the closest known asteroid to the Sun. Subsequently, it has the largest general-relativity effects of any object in our Solar System. Its surface gets hot enough to melt lead during its orbit.” https://scitechdaily.com/potentially-hazardous-planet-killer-asteroid-discovered-lurking-in-the-inner-solar-system/
