- Never seen anything like it. “In January this year, we became aware of an asteroid with the highest ranking on the Palermo scale that we’ve seen in more than a decade, reaching -0.66” explains Marco Micheli, astronomer at ESA’s NEOCC.
- Planetary defenders – always alert. On 7 January, one day after its discovery by the Catalina Sky Survey, asteroid 2022 AE1 was flagged for a potential future impact by the Asteroid Orbit Determination (AstOD) automated system that makes up part of the NEOCC’s suite of tools to assess the asteroid risk.
- The Sun never rises on ESA’s eyes on the sky … On the evening of Saturday 8 January, Marco ‘the impactor killer’ Micheli got hold of the 80 cm Schmidt telescope in Calar Alto, which the Coordination Centre has nearly continuous access to (weather permitting), to get more data.
- … until the Moon gets in the way. During a tense week over 12-19 January, 2022 AE1 couldn’t be seen as the Moon outshone the dim potential impactor. On top of this, the asteroid was moving further away in its current orbit and getting fainter at the same time.
23.49 [4] 2022 AE1 is a Tunguska event -sized asteroid, classified as a near-Earth object of the Apollo group, approximately 70 meters (230 feet) in diameter. [5] It was discovered by the Mount Lemmon Survey on 6 January 2022, when it was 0.09 AU (13 million km) from Earth. [1] On 9 January 2022 with an observation arc of 3 days, it was rated ...

Asteroid 2022 AE1 is an Apollo-type asteroid. It has an estimated size of 230 feet (70 m) in diameter. It’s more than three times the size of the small asteroid that disintegrated over the skies of Chelyabinsk, Russia, on February 15, 2013. It’s about the same size as the space rock that caused the Tunguska eventin 1908, also in Russia, which relea...
The fact is that asteroids are relativity small bodies in space. They are rocky or metallic objects, left over from the formation of our solar system some 4.5 billion years ago. As of January of last year, there were about 822,000 known asteroids. And more are being discovered all the time. Earthly astronomers are, of course, most interested in tho...
So, no, an asteroid will not cause fireworks on the 4th of July next year, as some media initially suggested. However, as is common with new discoveries, additional observations allowed astronomers to make more exact calculations of the space rock’s orbit. Yes, there is still some uncertainty. But, even so, the closest this space rock might come ne...

Mar 2, 2022 · For a few tense days this January, a roughly 70-meter asteroid became the riskiest observed in over a decade. Despite the Moon’s attempt to scupper observations, the asteroid is now known to be entirely safe.
