fears Just like all of us rocks are our best
- 00:24
friends They gave me our pets Okay so maybe not
- 00:27
everyone is is pumped up about rocks Is this guy
- 00:29
but those rocks hurtling through space or certainly more interesting
- 00:32
than your run of the mill paperweight over the centuries
- 00:35
we've come up with many cute little names for all
- 00:37
those wacky cosmic objects whizzing by over our heads You've
- 00:41
probably heard of all three of these guys but you
- 00:44
know the difference between him Would you be able to
- 00:46
identify one if it climbed a ladder and snuck through
- 00:49
your bedroom window when i e that's probably bad example
- 00:52
that would hurt you Call the police no matter what
- 00:55
type astrological body breaks in your house after dark Okay
- 00:58
so here's the low down on this stuff that's high
- 01:00
up we'll start with comets Comets are bits of icy
- 01:03
rock hurtling through space but because they're trapped in orbit
- 01:08
around a star they keep showing their face every so
- 01:11
often just how we're able to predict when comments like
- 01:14
remember haley's comet are due to make a return visit
- 01:17
come round round round they don't actually have flaming tails
- 01:20
shame because that'd be pretty cool Instead when they passed
- 01:23
close to the sun they heat up and they out
- 01:26
Gas was really know disgusting but because they're gashes emission
- 01:31
can't keep up with them It appears as if they've
- 01:34
got a tail As far as we know this is
- 01:36
the only comet with a tail All right Okay then
- 01:39
How about asteroids Well an asteroid is really just a
- 01:42
mini planet because it would be too hard for second
- 01:44
graders to memorise the names of one hundred fifty million
- 01:47
planets Astronomers decided a long time ago to assign a
- 01:51
different name to these lesser planetary bodies but like some
- 01:55
of them are really tiny smaller than your house even
- 01:58
some of them you might even be able to hey
- 01:59
in a fist fight Although don't try Many asteroids were
- 02:03
located in the asteroid belt and area between mars and
- 02:06
jupiter with a very high concentration of asteroids and is
- 02:09
any fashion conscious individual knows it goes great with a
- 02:11
pair of asteroid boots out of the picture Okay finally
- 02:16
meteors what's their deal well Every once in a while
- 02:18
a meteoroid or big honking piece of rock is sometimes
- 02:22
called enters first atmosphere But when it does that at
- 02:25
least behind a visible trail of light which of course
- 02:28
is the perfect time to kneel by your window in
- 02:30
which for peace on earth goodwill toward men and a
- 02:32
million dollars Yep meters are what we call shooting stars
- 02:37
right Fancy shooting star j h dot com for details
- 02:39
There really aren't stars at all even if they're made
- 02:42
out of similar stuff When a bunch of them entered
- 02:44
the atmosphere at one time you may be lucky enough
- 02:47
to witness a meteor shower although we still recommend bathing
- 02:50
yourself indoors So there you are Now you know a
- 02:52
little bit about thes floating rocks in space and hopefully 00:02:54.76 --> [endTime] they stay there You need to get some sleep
