Hi, my name is juliana Covic and this is my Astro bakery for my astro infomercial.
- 00:06 - 00:08
So um,
- 00:08 - 00:12
on the very back picture here that is Comet ison I put a
- 00:12 - 00:14
little caption at the bottom that you can read yourself if you need.
- 00:14 - 00:15
Um,
- 00:16 - 00:20
So at the time of this picture, it was roughly 97 million miles from the Earth.
- 00:20 - 00:25
Um, is taken at NASA's Marshall Space Flight Center on November 8, 2013.
- 00:26 - 00:31
Um, so if you can't tell by now this project is going to be about comments and um,
- 00:31 - 00:34
as we'll see later some asteroids and just
- 00:34 - 00:36
going over the similarities and differences of them.
- 00:37 - 00:38
So moving on.
- 00:39 - 00:44
So this page, it basically says the asteroid bakery has treats of all kinds.
- 00:44 - 00:48
Um, the main favorites are asteroid blends and comet rules
- 00:48 - 00:49
at the bottom.
- 00:49 - 00:52
I put a little tidbit saying both asteroids and
- 00:52 - 00:54
comets orbit the central star of the solar system,
- 00:54 - 00:57
although the orbits of comets are highly eccentric.
- 00:57 - 01:01
Um, so that's just one little similarity they share.
- 01:01 - 01:04
Um, in this picture here, this is actually an asteroid.
- 01:04 - 01:06
So the other one was comment, this is asteroid.
- 01:06 - 01:11
Um Again, there's a caption below it saying this is asteroid Bennu
- 01:11 - 01:13
believe that's how you say it. Um,
- 01:13 - 01:14
correct me if I'm wrong.
- 01:15 - 01:16
But those are the four sides of it.
- 01:17 - 01:24
And that picture was taken from Osiris Rex spacecraft polycom on two December 2018
- 01:24 - 01:26
and then cited my source.
- 01:28 - 01:30
Moving along, we're going to try some asteroid buns.
- 01:31 - 01:32
So starting
- 01:32 - 01:34
in the top right hand corner,
- 01:35 - 01:39
it says asteroids and comets are similar in some ways but very different too.
- 01:39 - 01:40
We're gonna move to the middle.
- 01:40 - 01:43
Now, according to NASA.gov, asteroids are rocky,
- 01:43 - 01:46
airless remnants left over from the early formation of
- 01:46 - 01:49
our solar system about 4.6 billion years ago.
- 01:49 - 01:58
The current known the current known asteroid count is 1,113,527 asteroids,
- 01:58 - 02:00
but everybody knows that right.
- 02:00 - 02:02
Um
- 02:02 - 02:05
so I think it's just really fascinating that they're
- 02:05 - 02:08
scientists are keeping up with the number of asteroids,
- 02:08 - 02:09
you know, that's really cool to me.
- 02:09 - 02:13
Um so let's talk about the classification of that. We're going to move down.
- 02:14 - 02:17
Asteroids can be classified into three different types.
- 02:17 - 02:19
There are C type as type and N. Type
- 02:20 - 02:22
C type is the most common type.
- 02:22 - 02:25
Um and these asteroids are composed of both clay
- 02:25 - 02:29
and silicate rocks which causes a dark colored appearance.
- 02:30 - 02:31
Then moving on you see the S. Type.
- 02:31 - 02:35
These are asteroids composed of both silicate materials and nickel iron.
- 02:36 - 02:38
Then you have em type which are metallic
- 02:38 - 02:40
and these asteroids are composed of only nickel iron
- 02:41 - 02:42
according to Nasa DACA.
- 02:42 - 02:47
That asteroids complete compositional defenses are related to
- 02:47 - 02:49
how far from the sun they are formed.
- 02:49 - 02:52
Some experienced high temperatures after they form and partly melted
- 02:52 - 02:55
when iron sinking to the center and forming
- 02:56 - 02:58
lava to the surface.
- 03:03 - 03:06
Then we're going to move along to our
- 03:07 - 03:08
comment rolls.
- 03:09 - 03:09
Oh sorry
- 03:10 - 03:10
too far.
- 03:10 - 03:12
Okay, so
- 03:12 - 03:16
starting in the middle, it says comments on the other hand are leftovers from
- 03:17 - 03:19
The formation of the solar system in which dust,
- 03:19 - 03:22
rock and ice were combined according to NASA DACA,
- 03:22 - 03:27
the current number of known comets, it's 3,743.
- 03:27 - 03:29
Again, really fascinating that they're keeping up with us
- 03:30 - 03:30
um,
- 03:31 - 03:32
up in the top right.
- 03:32 - 03:34
You can see within the last century the guideline of
- 03:34 - 03:38
naming comets has changed the majority of the time.
- 03:38 - 03:42
Comets are named after their discoverer, which could be person or space problem.
- 03:42 - 03:46
Then at the very bottom is perhaps the coolest thing I've learned um,
- 03:46 - 03:48
which is awesome tales they have,
- 03:48 - 03:52
I think they are just really cool and honestly really pretty there,
- 03:53 - 03:54
it's really interesting.
- 03:54 - 03:59
Um so they are formed from dust and gasses after comet has heated up next to the sun.
- 04:00 - 04:04
Then I said then I stated Nasa dot gov When
- 04:04 - 04:06
the comments orbit brings it close to the sun,
- 04:06 - 04:08
it heats up and spews gas and dust,
- 04:09 - 04:13
dust and gasses into a giant glowing head larger than most planets.
- 04:13 - 04:15
The dust and gasses form a tail that stretches
- 04:15 - 04:17
away from the sun for millions of miles.
- 04:21 - 04:21
Mm hmm
- 04:23 - 04:27
That is really the end of my presentation.
- 04:27 - 04:32
Um this is just a little uh summary of my project.
- 04:32 - 04:35
So overall the differences among our comment rolls and
- 04:35 - 04:39
asteroid bunds is very noticeable with different classifications,
- 04:39 - 04:40
ingredients and important features of them.
- 04:41 - 04:42
Although this is true.
- 04:42 - 04:45
Both these treats are important for the astro bakery to stay balanced
- 04:45 - 04:46
and running for millions of years to come.
- 04:46 - 04:49
We appreciate your support and can't wait to see you in the stars.
- 04:49 - 04:53
So that's basically basically me just saying um that comments
- 04:53 - 04:58
and asteroids are very important for our solar system to um
- 04:58 - 04:59
just
- 04:59 - 05:02
continue on and stay in balance.
- 05:03 - 05:05
So yeah, that is
- 05:06 - 05:08
the end of my presentation
- 05:10 - 05:11
and this just takes you to my work cited where
- 05:11 - 05:14
you can see two of these are the pictures that
- 05:14 - 05:19
I used and then the rest are where I got my source right where I cited my sources from.
- 05:19 - 05:20
So
- 05:21 - 05:24
thank you for listening and I hope you enjoyed my presentation.
