Nice find OP, I was wondering where the .2 LD came from on spaceweather.

I'm curious about the 5LD on Oct 30, that's 595Meters

interesting

The average distance from Earth to the Moon is 384,403 kilometers (238,857 miles).

They dont mean the navigation LD.

That's how I came across this.... I was checking the sunspot count on spaceweather.com.... looked at the Near Earth Asteroids section and saw 0.2LD!!!! WTF??? 0.2LD!!! Only found yesterday!!! Yikes!!!

Approximate diameter: 8 meters
Its a non event

Yeah .2LD's only 76880 kilometers lol

How do they not know this stuff sooner?

.2 lunar distance is close.
If that asteroid is made of iron and it is 30 feet long.... wow... look out below!!!! That could take out a big city!

What happens if it hits the moon? We say good bye to high/low tide?

0.2 LD is not such a big deal. I'd be worried about the ones they still haven't seen.

I was thinking the same thing bre.... the big fireball and 100 meter crater in Columbia yesterday! Interesting indeed!

you know werner von Braun is right on track and thats scary as hell!

Sowjetdoom

Asteroiddoom <----YOU ARE HERE!

Alien DOOM!

Plus the closest approach uncertainty of 7 minutes!!!! Can't JPL be a bit more percise?

Catcher's Mit material.

i've already post it yesterday

Thread: asteroid missing earth by .2 lunar distance on september 8th

source?

They only have 1 day's worth of observations, so no, not really. You need to observe over a longer period of time to refine the orbital determination, preferably no less than 3 days. I'd love to watch this one as it whizzes by on the 8th, but unfortunately my laptop's power cable basically bit the dust at the end of my last broadcast on Friday night. I'm pretty sure the replacement won't be in in time :(

This is SCARY!! this is the one that's due to swing by in October uv11

Take that, hand! That would blast through a skyscraper. A car into a tin can, ect. Cannot say I have ever seen it happen personally, but damn.

So its as big as a small house- big deal.

8 meters in Dia. Could easily take out a city the size of New York !!!!!

Ive been watching that list for weeks and the red letters are growing. I just checked it this morning and couldn't believe my eyes! All those near passes were not there last time I looked...

Hey.... my 1st pin!!!!! Thanks mods!

Not much notice for something passing so close.

Would a rock 50000 miles from Earth cause a disturbance?

this is NOTHING. quit being such pussies

Yep.
