COMET, METEOR OR ASTEROID - The REAL difference.

What is a shooting star exactly? There is a vast amount of rocks and debris floating around in space. Around 100 tons of it falls to earth every day. You might have been lucky enough to have seen a shooting star, but do you know whether it is a comet, meteorite or an asteroid?

Comet, meteor or Asteroid?
Intro
There is a vast amount of rocks and debris floating around in space. Around 100 tons of it falls to
earth every day. You might have been lucky enough to have seen a shooting star, but do you know
whether it is a comet, meteorite or an asteroid?
what is the difference between these 3 objects? Why are we landing satellites on asteroids and
could life have been brought to earth on one of these rocks?

Main
Comet
A comet (also called a dirty snowball) is essentially ball of ice, rock and dust that orbits the sun,
ranging in size from around 1km to 20km.
Astronomers believe they are leftovers from the early formation of the solar system that reside in
one of two places on the very outskirts of the solar system; The Kuiper belt and the Oort Cloud.
These two areas are made up of small icy bodies (and Pluto) of frozen gases such as methane,
ammonia, nitrogen and water mixed with rock and dust. Occasionally a comets orbit will be altered
by a gravitational tug of another large object or through a collision with another body that might
send it into the inner solar system or sometimes even straight towards the sun.
As a comet starts to move closer the sun, it heats up and ice starts to evaporate and form a cloud
around the nucleus. Solar winds from the sun push the cloud to make a tail on the comet, also called
a coma. The coma creates a spectacular light show for us on earth and these tails can reach up to
150km in length.

Asteroid
Nearly all Asteroids are odd shaped chunks of rock that orbit the sun in the asteroid belt between
mars and Jupiter. Some though are thought to be made of metals like nickel and Iron.
The asteroid belt is thought to be either leftover mass from a failed planet forming due to the close
gravity pull of Jupiter or the leftovers from a planet that broke up due to a collision.
They come in sizes from a few meters to just under a 1000kilometers wide. Ceres is the largest we
have ever found and is 960km wide which is about as wide as Texas and big enough to be classed as
a dwarf planet. Some asteroids also have their own moons!
Also if you condensed all of the asteroids in the belt together they would still be smaller than our
moon.

Meteoroid
Space debris smaller than asteroids are called meteoroids. These can be as big as a few meters and
as small as a grain of sand. They are usually bits of asteroids that have collided or leftover debris
from a comet.
When a small meteoroid gets close enough to enter in the Earth’s atmosphere it starts to burn up
completely and creates a dazzling trail of light due to the air resistance it encounters. This is called a
meteor, or as we sometimes call them, shooting stars.
Every year around mid July the Earth’s orbit takes us through the dust and debris left behind by a
comet. This is called the Perseid meteor shower and creates an incredible display of shooting stars
with around 80 shooting stars an hour. You can find out more about this and how to view the
spectacle in the link at the end of the video or in the description below.
90-95% are vaporized n their approach to earth but when a rock survives this and hits the earth’s
surface, it is called a meteorite. They are usually about the size of a pebble but we have found a
3-metre-wide 66 ton tablet shaped meteorite in Namibia that fell about 80,000 years ago.

Our next collab is with Rolling Routes, get familiar with these amazing guys now and show them some love before we make our cideo together :)

So: a Asteroid is a giant space rock that isn't a moon and doesn't have enough size to be a planet/dwarf planet, and orbits a star along with other asteroids making a kind of star ring; Meteors are space rocks that are less than 10 meters in size and are normally created by asteroids coliding; Meteorites are meteors that have crashed on Earth which decreased in size because most of it burned off; Comets are like asteroids, but made of ice, rock, and dust, because of that it creates cool tails when getting closer to the Sun

I know this is an old video but this is the first time that I am watching this channel. I had to do a research project for school and submit it online cause of the Corona Virus. I am a visual and auditory learner and this video was exactly what i needed. I hope i do good on it cause I really wanna raise my science mark :)

[aestheticanimemusic]

The video was very helpful, now I understand the different definitions of comet, asteroid, and meteor

[WordplayEnglishLanguageCenter]

Thanks for answering our question, "What is the difference between a meteorite and an asteroid?" We watched this videos with our students here in Hanoi, Vietnam.

[hissimasnake]

This was really helpful for my school.

Note: Oort cloud/Long Period comets travel more than 200 years
Kuiper belt/Short Period comets travel up to 200 years or less

[smritiguha]

It is right for us to understand about the comets, meteorods and asteroids. Nice video.

[watzup]

I'm just here cause I don't wanna 0 on my grade. ._.

[nathanielreedy]

I found this video very helpful.
You say that asteroids range in sizes from 10 m - 1, 000 km. What is your source for this definition? Why wouldn't they be defined by mass?

This channel is so underrated, you deserve more subs.

_Cool, informative, and like always, beautiful science._

[cutiebuggg]

Thanks this is helpful 😊 I liked you accent !

[selinayu]

This is really helpful for my activity in school my teacher gave me.

[amalinajsh]

May I know what kind of apps that you use ?

[jabber]

Why had this channel not uploaded in months? And why does it not have more subscribers!

[tearly]

This really helped me i'n here bc of homeschool but its also cool 0.0

[littlemummie]

This is really helpful.
Great job in making this video .
