On November 18th, 2022, shortly earlier than midnight, the Catalina Sky Survey (CSS) in Arizona and different observatories worldwide detected a small object (now designated 2022 WJ1) heading towards Earth. For the subsequent three hours, the CSS and the Southern Ontario Meteor Network (SOMN) on the College of Western Ontario monitored the item earlier than it entered Earth’s ambiance above Southern Ontario. At 03:26 a.m. EST (12:26 a.m. PST) on November nineteenth, the item appeared as a shiny fireball that scattered meteorite fragments throughout the Niagara area.

This occasion triggered a global collaboration to seek out the fragments for evaluation, however none have been discovered but. In a recent study led by Western College and Lowell Observatory, a global workforce of scientists described a brand new method for finding out near-Earth asteroids (NEA) based mostly largely on 2022 WJ1. The examine is critical in that the workforce decided the NEA’s composition—the smallest asteroid characterised thus far—and established a brand new and built-in methodology for finding out different NEAs which will impression Earth sometime.

The examine was led by Dr. Theodore Kareta, a Postdoctoral Researcher from the Lowell Observatory. He was joined by researchers from the College of Western Ontario, the ESA’s Planetary Defense Office (PDO), the School of Earth and Planetary Sciences and the International Centre for Radio Astronomy Research (ICRAR) at Curtin College (Australia), the College of Zagreb (Croatia), the Astronomical Society Istra Pula, the Višnjan Science and Education Center, and NASA’s Jet Propulsion Laboratory. The examine that describes their approach, “Telescope-to-Fireball Characterization of Earth Impactor 2022 WJ1,” was printed on November twenty second in The Planetary Science Journal.

The detection of 2022 WJ1 (WJ1) earlier than it entered the ambiance was a fortuitous occasion because it gave astronomers simply sufficient time for scientists to telescopically observe it and collect exact data on its place and movement – which have been used to refine its orbit. These components additionally allowed astronomers to find out that the asteroid would enter Earth’s ambiance above the Nice Lakes area. The impression location was additionally fortuitous because it landed in the midst of Western’s community of meteor-observing cameras.

The three hours it took for WJ1 to enter the ambiance additionally allowed a number of members of the Western Meteor Physics Group and Western’s Institute for Earth and Space Exploration (IESE) to observe the item streak by the sky. This was the primary time in historical past that observers have been alerted of a pure fireball forward of time and knew precisely the place it could be seen. Paul Wiegert, a professor of physics and astronomy at Western and a examine co-author, witnessed the fireball at 3:30 a.m.

“I watched from Brescia Hill on the Western campus,” he mentioned in a current Western Information press release. “Although chilly and windy, the hill had a transparent view to the east, the place I anticipated to see solely a distant flash. Then, the fireball all of the sudden appeared, passing virtually overhead. It was simply seen between damaged clouds and noticeably orange-red.” The Lowell Discovery Telescope‘s (LDT) capability for fast and secure monitoring made it the perfect instrument for observing WJ1, permitting it to maintain up with the small and fast-moving NEA.

Teddy Kareta, a postdoctoral affiliate at Lowell Observatory, noticed the asteroid together with his workforce for about one hour earlier than it was misplaced within the shadow of Earth. As he indicated:

“On the time that we misplaced the asteroid – when it received too dim to be seen in our photos – we had the telescope shifting at 5 levels per second to attempt to sustain with it. That’s quick sufficient that the majority different telescopes would have had to surrender significantly earlier. It’s tremendously fortuitous that this asteroid occurred to fly over Arizona’s darkish skies at evening earlier than burning up over Western’s glorious digital camera community. It’s arduous to think about higher circumstances to do this type of analysis.”

By evaluating the Arizona-based observations to footage of the meteor acquired by the SOMN, the workforce decided the dimensions and composition of 2022 WJ1 (WJ1). The dimensions was decided due to observations made by the LDT, which detected a silica-rich floor that gave the item a comparatively excessive albedo (reflectivity). By measuring this mirrored gentle, the workforce calculated the diameter at 40 to 60 cm (16 to 27 inches), making it the smallest asteroid on document.

The mixed telescopic and fireball digital camera knowledge counsel that WJ1 is wealthy in silica, inserting it within the S-chondrite class. They’re among the many oldest our bodies within the Photo voltaic System and the most typical sort of meteorite to hit Earth. “That is solely the sixth asteroid found earlier than impression,” said Denis Vida, an adjunct professor of physics and astronomy at Western. “Our new method, discovering an asteroid by area statement after which subsequently observing it with cameras from the bottom, allowed us to substantiate that our estimates match effectively to estimates derived utilizing a very completely different method.”

“That is solely the second time that an asteroid has been meaningfully characterised with telescopes previous to it impacting the Earth,” said Kareta. “It’s a testomony to our good luck and preparation, however it’s additionally as a result of group that cares about retaining the Earth protected from these impactors studying to work collectively higher. This primary-ever comparability between telescopic and fireball digital camera knowledge is extraordinarily thrilling and means we’ll be capable of characterize the subsequent asteroid to impression the Earth in even higher element.”

Whereas no fragments have been discovered within the Niagara area, and no additional official searches are deliberate, there are nonetheless folks within the space who’re looking out and know what to search for. Whereas a lot of the fragments have been predicted to fall into Lake Ontario, some are hopeful {that a} fragment or two might flip up within the close to future.
