Space rock hits house

American collectors with open chequebooks are expected in New Zealand
within days to bid for the 1.3kg meteorite which exploded through the
roof of an Auckland house yesterday.

The hit is a billions-to-one event which adds thousands to the value
of the grapefruit-sized rock which plummeted through the tiled roof of
Phil and Brenda Archer's Ellerslie home at 9.30am.

Collectors are also expected to begin combing the suburb for other
pieces which may have survived the molten descent.

It is only the ninth meteorite ever found here and the first to hit a
home. The last one was found in 1976 but it is not known when it
landed. Worldwide, such strikes happen only once every three or four
years.

"I was in the kitchen doing breakfast and there was this almighty
explosion," said Brenda Archer. "It was like a bomb had gone off. I
couldn't see anything, there was just dust. I thought something had
exploded in the ceiling. Phil saw a stone under the computer and it
was hot to touch."

The rock hit her leather couch and bounced back up to the ceiling
before rolling under the computer. The Archers' one-year-old grandson
Luca was playing nearby just minutes before the impact. "He must have
a guardian angel," she said.

Experts have told the Archers to keep the rock in the oven at 100C to
dry it out. They plan to take it to Auckland University tomorrow.

Their insurance company will pay for the hole in the roof and couch
and two holes in the ceiling.

My thoughts exactly. Somewhere in the policy, buried in fine print, there's
bound to be a clause excluding damage due to falling space rocks and garden
gnomes.

Any takers ???

It happened just along the road from where I used to live. I wonder
if this woudl come under "Acts of God" fine print in the policy?
Bet the owners were glad they weren't sitting n the couch at the time
it arrived...

"act of God" is the usual clause. On the other hand, an insurance
company that did pay up on the claim would have a bonanza in
advertising.

It'd be interesting to know what kind of meteorite it is, the metallic
ones can sometimes be forged into decent cutlery.

From the blurry media shots I saw, it wasn't metallic, but looked like
a chondrite. Ancient stone; silica, aluminum, whatnot.

But hay, what silica, aluminum, whatnot is NOT ancient?

C'mon. I would think that a meteorite would have enough energy to go through
more than just the roof. Kind of like shooting through a thickness of wood
with a rifle, and slowing the slug down enough to catch it with a gloved
hand. Volcano eruption in Indonesia ejecta maybe?

Not in that size, especially if it was ejected from a larger mass:

Collectors are also expected to begin combing the suburb for other
pieces which may have survived the molten descent.


Whence it may have been given an upwards kick on breaking up, slowing it
within more natural speeds rather than the initial interplanetary velocity.
Especially if it's rock... 1.3kg would be like 4" across.

I'm SURE the insurance company will pay for the damages..... They will,

bits from the ceiling and other repairs; oh yeah, that "rock" that did
the damage will also have to go.

He they pay up for earth quakes in Ca, tornadoes in Lubbock TX and

Maybe after being vacuum dried for so long, it would be in their best
interests to keep it dehydrated. If nothing else there could be hygroscopic
salts that would ruin the rock if they got wet.

Years ago, I saw a picture of a woman who had been struck by a
meteorite. The piece that struck her was small, pea sized. This woman
was hugely fat and had a giant bruise on her side. I looked at the
picture with horrible fascination. I wonder now if it was a hoax? I
know pieces of meteorites can be moving slow enough to stop once they
crash through a roof, but that lady being struck by one has always
rankled.

and remember- velocity is relative. Earth is moving, as is the chunk
of space rock. if both are moving at about the same speed in about the
same direction it will have an impact speed about what gravity gives
it as it falls... still enough to bust through your roof.

Even so, you have the gravitational potential energy (wow that's an
incredibly long couple of words for something so simple) of falling to Earth
a few thousand miles... that's a generous acceleration and will have it
streaking hypersonically through the atmosphere anyway.

Neglecting air friction (which you can't) an object falling from rest at
infinity will acquire a final velocity of 7 miles a second at impact with
the Earth's surface (same velocity as escape velocity for something
going the other way).

Relative orbital motions can boost that into the 20 to 40 miles per second
range, or slow it to only a few miles per second, depending on the exact
geometry. But even an object at relative rest at 200 miles above the surface
would acquire a final velocity of around 5 miles a second by the time it
reached the surface.

However, you can't ignore air friction. An object with a fairly poor drag
coefficient will be slowed greatly by atmospheric friction. Most relatively
small meteors are moving relatively slowly by the time they get deep into
the atmosphere, often subsonic.

They also often break apart as they plow deep into the atmosphere.
That's why you can often pick pieces of one up and find them *cold*
rather than hot (these pieces came from the interior of a larger meteor
which broke up after spending most of its energy against the atmosphere).

I'd note that the large amount of relatively intact debris which reached
the ground from the Shuttle Columbia is another example of this.

Gary:

You didn't mean 2,000 miles, or maybe .5 miles/second, did you? I did some
quick back-of-the-envelope calculations, with the assumption that gravity is a
constant regardless of altitude. Which of course it isn't, but it makes things
easier.

Not that I normally check things like that, but when I saw 200 miles and 5
miles per second, and thought "OK, that's 80 seconds", it seemed like too high
a final velocity for only 80 seconds.

Agree with all your other points, though.

As a follow up check

"The Archers have been paid out by their insurance company for the
damage."

But

"They will meet two representatives from Wellington's Te Papa next
week to talk about how to make a professional display with the
meteorite.

Phil Archer said the display was likely to include the couch and
ceiling which was damaged by the rock's entry into their home."

Sheesh! Has interest in science descended to the point where the human
factor and experience has to be emphasised?
