Who Defends Earth From Asteroids? - Cheddar Explains

The most important job on Earth is definitely Planetary Defense Officer. Lindley Johnson, from NASA's Planetary Defense Coordination Office, monitors all asteroids around Earth to make sure we find them before they hit us and have global consequences.

"Planetary Defense Officer" is easily the most badass job title ever.

Real life lore anyone? #goatlivesmatter

Who protects the Earth from asteroids? *JUPITER*

[jonathanward]

I was expecting an explanation of what the plan is to defend the earth if one was on a collision course

It's a piece of cheddar that saves Earth from space.

So guys, we did it. We defended Earth from a quarter of a million asteroids, 250, 000 asteroids, and still growing.

Who else is here from Reallifelore video?

Wrong HEADER for the video! NASA just REPORTS not DEFENDS!

[theboss-ojvo]

Wait so if something is going to collide with earth all your gonna do is give us a heads up ? Wtf I was expecting Bruce Willis film (I can't remember the name of it) type of shit to happen

I thought we had a triangular ship that could blast large asteroids into smaller ones, then eventually obliterate them.

We just have to watch out for alien ships, particularly the smaller ones as they have better targeting systems.

I was brought here by Austin McConnell. Good video, and your other videos also look worth watching, I'll definietly check them out. You may have just got a new viewer!

I like the way you subtly added subtitles in pink when the scientist's voice was incomprehensible (useful for at least for non-native English users)

[Piemasteratron]

I just wish people would stick to metric when talking about space. I'm used to miles but it's really jarring to flip from kilometres, to feet and back to metres in the same video. STICK TO THE SAME SYSTEM PLEASE!

Actually, the difference between asteroids and meteorites is not size. "Asteroid" is when they're in Space, and "meteorite" is when they are going to fall through an atmosphere. "Aster" = star, "-oid" = like, "meteor" = falling from the sky, "meteorite" = thing that fell from the sky.

[CarloRizzante]

An asteroid that size coming closer to Earth would also be a massive opportunity to study it, and possibly to capture it within a stable Earth's orbit.
