Scientists estimate that 2024 YR4 is between 130 to 300 feet (40 and 90 meters) wide, large enough to cause localized devastation near the impact site. The asteroid responsible for the Tunguska event of 1908, which leveled some 500 square miles (1,287 square kilometers) of forest in remote Siberia, was probably about the same size.

So nothing to worry about

Provided it enters in a similarly uninhabited location.

Sarcasm?

Idk about you but if it levels 1287 km² of forest, I don't think that would exactly be good news for a populated area. On the upper range, it could be equivalent to a 40 megatonne bomb.

I'm team asteroid.

Which direction do I need to fart to up those numbers?

[–] Uranus_Hz@lemm.ee 6 points 10 hours ago

Those are rookie numbers. Gotta pump those numbers up.

Panic?

I'm crossing my fingers for the wellbeing of the universe. We're awful.

[–] floquant@lemmy.dbzer0.com 9 points 12 hours ago (1 children)

Worry not, for we are insignificant to the universe.

Forever, humanity could only ever conceivably expand so far due to the expansion of the universe, so as far as we know a still insignificant portion of the universe we could colonize.

[–] pjwestin@lemmy.world 13 points 14 hours ago (2 children)

That's 0.9% more than the last time I checked. I know those are still really low odds, but we can hope...

[–] psud@aussie.zone 3 points 8 hours ago

One of the things they're doing is calculating what it's orbit would have to be to hit the Earth, and where it would have had to have been on its last orbit to be in that orbit

So they can look at any astronomical images of that part of the sky from then and see if it's in the right place

If they find images of the right part of the sky at the right time and the asteroid is not in it, they know it's not on an orbit that will hit the Earth in 2032

don’t worry, it’ll just be like a small nuke, not a planet killer… (until they update the size estimates)

Better late than never I guess.

I’ll only panic if it misses

[–] HappyStarDiaz@real.lemmy.fan 7 points 17 hours ago

Is there any way to speed this up

[–] InFerNo@lemmy.ml 4 points 15 hours ago (1 children)

If we are able to nudge an asteroid, would an asteroid of this size nudge the earth?

Technically the solar system is a multi-body system, and everything nudges everything else, but the mass of the earth is far greater than the mass of the asteroid, to the point that it doesn't matter.

[–] Yawweee877h444@lemmy.world 4 points 15 hours ago (1 children)

Sigh. Why can't it be 109%

This place sucks.

[–] psud@aussie.zone 3 points 8 hours ago

It's not big enough to fix anything. If it hits, it won't hit America or Europe

It's in the big nuke scale of energy, enough to do a lot of damage to a small area. Were it to hit a city, the city would need a lot of rebuilding. Were it to hit, few people would be in danger as we will have years of warning. The only people in the impact area would be "storm chasers" travelling to see the impact

[–] MrTrono@lemmy.world 85 points 1 day ago (12 children)

Am I supposed to panic because it's unlikely to hit? Meanwhile I'm out here wishing for death by meteor.

Panic?!

You mean throw a welcome party?

[–] GrumpyDuckling@sh.itjust.works 1 points 13 hours ago

I wonder if the "important" people know the chances are higher, so they're going for broke in order to build their escape ship.

[–] vga@sopuli.xyz 14 points 23 hours ago* (last edited 23 hours ago) (8 children)

Can we launch a satellite at it, perhaps detonate a huge nuke on it to make that chance higher?

Wait, we could just detonate all those huge nukes here right now. Show that stupid asteroid.

To people having panic attacks, it is not large enough to destroy the earth, and we would have plenty of time to evacuate the impact location. Though let's hope it isn't anywhere with permafrost.

i don't like those odds. anything we can do to bump it up to around 75%-100%?

Okay so how big is this meteor then

[–] psud@aussie.zone 1 points 8 hours ago

Were it to hit it would hit like a large nuke

[–] GooberEar@lemmy.wtf 10 points 18 hours ago

It's around 1000 millimeteors

[–] everett@lemmy.ml 10 points 20 hours ago (1 children)

Exactly one meteor wide. Do you need the height as well?

[–] dellish@lemmy.world 2 points 12 hours ago (1 children)
[–] everett@lemmy.ml 1 points 10 hours ago

The meteorest.

[–] Norgoroth@lemmy.world 6 points 20 hours ago

130 - 400 meters
