00:00

Thank you We sneak in comets asteroids and meteors Allah

00:06

shmoop all right This is iraq And this is iraq

00:11

If they're not just lifeless motionless hunks of minerals oh

00:13

no they're alive Really They're alive They move through space

00:17

with purpose They have personalities they have hopes dreams and

00:20

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
