Designated 2022 EB5, the small rocky object impacted the planet on March 11 north of Iceland, according to numerous astronomers online. . . .

There's nothing ....."left to the imagination." There's a 100-percent chance that it's going to happen again. However (COMMAAA) What will the effects be from a medium-sized rock? The Problem I've always had with climate science is much the same as we've seen with epidemiology.....only critters and mostly-critters are a lot easier to study. Global-warming May Have Been Jump-started By The Tunguska Meteorite Churning Up Atmosphere -- ScienceDaily The year without a summer – Climate Change: Vital Signs of the Planet Yeah.... I know. One is a volcano and one was a rock or some have said...a comet, but one imagines that a VOLCANO (spewing lots of GHGs and some particles) would do one thing to climate, while an energetic rock 'throwing shade' (pun almost unintended) and perhaps causing some outgassing - would do another. "Some studies" have investigated contrary hypothesis....because..... Climate is complicated. OTOH.....it might be a self-licking lollipop. Tunguska was about a 65 metre rock. Another rock thrown at Russia in recent memory (the Chelyabinsk meteor) was a 20-metre stone and it distributed about a half-megaton of energy non-atmospherically, causing hundreds of injuries and some non-trivial property damage. Rocks come in MUCH larger sizes - but of course THOSE are easier to track, right? Either way....they are GOING to cause "climate change" - right? The relative sizes of cosmic billiard balls compared with the damage potential ought to leave people wondering why we are pouring a vast amount of treasure into local energy sourcing and a relatively paltry amount into non-local rock hunting....... Things that make you go hmmmmmmm......
More awareness leads to budgets and better detection systems. Sun approaching meteor remains a hard problem. Bob Wilson
Covered also at EarthSky | Asteroid discovered hours before Earth impact But their 'incoming image' is of a different object. It was 3 meters diameter (other sources suggest 2 m) and intercept velocity about 2.7 km/sec. Call density 5 gm/cm3, and energy transfer can be estimated. Incoming below 10 meters are not rare according to == Whether this one came from 'sun side blind side' or otherwise escaped earlier notice is not known to me. "Few people get hit by the bus..." metaphor teaches nothing here. People and buses can see and avoid. Meteors have no 'avoid'. Earth as a planet might someday later do redirecting. Might, someday, later. Until then, bring 'em bro.
