Cat's Eye Nebula


We've learned about the planetary nebula, and the clownface nebula.

There are even more cool things in space like this!

The Cat's Eye Nebula is actually a planetary nebula with a star inside of it!

It's over 3,000 light years away, and is part of the constellation of Draco.

Clownface Nebula


We just learned that a planetary nebula is a bunch of burning gas in space that was shot out from a red giant star.

There are some really amazing looking planetary nebulas in outer space,
like the clown face nebula.

It's over 2,000 light years away, and is part of the constellation of Gemini.

Planetary nebula


A planetary nebula is a bunch of burning glowing gas that was shot out from a red giant star at one point.

Black hole


A black hole is an area in space that has gravity so strong
it will suck in anything, even light!

Interstellar cloud


An interstellar cloud is a big bunch of gas, plasma and dust floating together in space.

Asteroid belt


We've learned about asteroids and we've learned about the kuiper belt which is full of asteroids.

It turns out there is an even larger bunch of asteroids in our solar system
called the asteroid belt.

There are over a million asteroids in the asteroid belt!

Atmosphere


We just learned about how meteoroids become meteors or shooting stars when they get close to a planet.

They burn up because of a planet's atmosphere.
The atmosphere is the air up in our sky!

Just think about how a strong wind feels blowing on your face.
That wind is maybe blowing at 20 miles per hour.

Now imagine that wind blowing at 100,000 miles per hour!
That's how fast some meteors travel when they enter Earth's atmosphere,
and they burn up because they're going so fast they can't handle that kind of wind.

Meteorite


We now know that an asteroid is a big rock flying in space,
a meteoroid is a small chunk broken off of an asteroid
and a meteor is a chunk of that meteoroid that burns up in the sky when falling to a planet.

So what's a meteorite then?

If a meteor enters a planet's sky and doesn't burn up all the way,
sometimes it actually hits the planet.

When it actually hits the planet, it's called a meteorite!
Most meteorites are really small like a baseball and don't cause any damage, others are bigger than a car!

Meteoroid


A Meteoroid is a smaller piece of a comet or asteroid that has broken off and is floating into space.

When a meteoroid gets close to a planet, it will burn up in the sky.

The burning up is very bright, and it's what we call a shooting star or meteor.

Comets


A Comet is like an asteroid, but it has a glow around it called a coma and sometimes has a glowing tail

(from: wikipedia - comet)

Comets get a coma and tail when an asteroid gets close to the sun,
and parts of it start to burn up and turn into gas.

Asteroids


We learned last time about the all of the things like Pluto that were floating around in the Kuiper belt.

All of the things floating around in our solar system that aren't planets,
are called asteroids.

Kuiper Belt


Remember we talked about Pluto and how it's part of something called the Kuiper belt?
(kuiper rhymes with viper)

Well it turns out that lots of things are floating around in that area,
over 100,000 different things called Kuiper Belt Objects or KBO for short.

They come in all sizes, some even close to the size of Pluto!
