Russian 'meteor' was actually a tiny asteroid, NASA says (45 feet across, 10,000 tons & 40,000 mph)

45 foot squared and cubed would be 3375 cubic yards
3375 X 4000= 13.5 million pounds
Divided by 2204 lbs = 6125 metric tonnes
If the matter approximated water...granite...ash.... silicates....iron.....clay....slag.....calcium sulfate and most importantly limestone

Using a plane in this diagram....a deliberate reminder of 9-11??

Planes are a pretty common scale comparison.

On a related note, Lucifer’s Hammer by Niven and Pournelle is a great book about the aftermath of large meteorite strike on Earth. Highly, highly recommended. And Pournelle is an old school conservative. Besides FreeRepublic, he’s the only guy I send money to, to support him and his web site.

Nice pics. Do you or anyone else know why we are not seeing moonstrikes? With all these asteroids buzzing, I would think the moon should get hit.
Actually I have read where asteroids become meteors and strike the earth every day but they are small ones.
I would think we should have see some good sized ones hit the moon and kick up a huge cloud?

That’s some muzzle velocity.

Actually meteors do hit the Moon with regularity and have been observed, sometimes by amateur astronomers with backyard telescopes.

The moon gets hit all the time. They're recorded as flashes usually classified as transient lunar phenomena. The reason reason they don't just call them impacts is because not all are impacts. Some are believed to be flashes caused by static electricity or other little understood phenomenon.
At between 250,000 and 500,000 miles a flash needs to be pretty big to be seen with the naked eye and few are. If a nuke were detonated on the moon its pretty likely that it would go unnoticed by anyone not watching for it.
Tons of meteors enter our atmosphere every day but most are the size of grains of sand and burn up in our atmosphere. Obviously the moon gets hit by the same but they're so small that we're not going to see them.

As I said; outside the atmosphere its an asteroid. While falling through the atmosphere its a meteor. I was taught to remember the Latin roots in a high school meteorology and astronomy class. Astro, astronomy, asteroid. In outer space. Meteor, meteorology, within the atmosphere. Meteorite, stalagmite, stalagtite, the "-ite" suffix is a geological reference, so it's on the ground.
Pretty basic linguistic distinctions, really. But people have somehow gotten the notion that the terms refer to size, including the erstwhile genius Michael Medved.
Oh well, it won't be the first time he's been wrong and certainly won't be the last. Pity he'll never know it.

Thanks for the answer. Bottom line = it would take a very large moonstrike to raise a dustcloud large enough to be seen well from Earth

Why a basic working knowledge of Latin is important. The Latin root words are kind of like a linguistic library. The root word puts you in the right aisle.

The part we see is facing us, so the impacts are less frequent being somewhat sheltered by the Earth itself, but they do occur. I’ve understood that the “dark” side is far more pocked with craters and that impacts are much more frequent.
