  • Jack.
  • Yes.
  • Hey, man.
  • So you know, there's this latest StarTalk book that yes, Lindsay Walker and I wrote to be on.
  • Yeah, she's behind the scenes and all these recordings, of course, producer extraordinaire.
  • We spend a large part of a chapter exploring
  • how empty the space actually is.
  • You can get a sense it's empty because there's these big, vast voids and things, all right, but I don't think people really feel how emotionally empty.
  • They came out wrong.
  • Space is just sitting around just like, I want to connect with people.
  • I want to.
  • I just, I don't understand why I just can't seem to make that kind of tight fit with anybody.
  • I don't.
  • It's tough being space.
  • God, it just seems like no matter how much comes into me, I just still feel so empty.
  • I mean, new stars are happening all the time, but still, it just doesn't do it.
  • What do I have to do to have some sense of accomplishment or fulfilledness in my life?
  • I'm sorry, space, our time is up.
  • Maybe we can pick this up next week.
  • Space.
  • So let's take a look.
  • We have eight planets, and they go out, you know, four or five billion miles.
  • But there's only eight of them, right?
  • So clearly that's pretty empty, right?
  • Yeah.
  • But you know there are these asteroids.
  • right and most of them are collected in this flattened zone yeah between mars and jupiter right okay because it's a flattened zone we call it a belt there are comets
  • that come into the sun from all directions, and if you projected where they come from, it's a spherical region around the solar system, and we wouldn't call that a belt, because it's a spherical region, we'd call that a cloud.
  • A cloud, right, the Oort cloud.
  • The Oort cloud, Jan Oort, who's a Dutch astronomer.
  • So he saw how many comets were coming in from every direction, and comets are moving fast when they're near the sun,
  • Right?
  • And when they go farther away, they move slower and slower and slower.
  • So when he did the, when he ran the math on the, before computers, by the way, he ran the math.
  • he concluded there must be billions of these comets way out there in these long loop orbits that come around.
  • And they'll spend most of their time far away from the sun, because that's when they're moving the slowest.
  • Pluto is the most significant member of the Kuiper belt of comets.
  • So that's a belt, because it's a flattened region around the sun.
  • All right, in the year of the first asteroid is discovered.
  • And people were excited because they think it's a planet.
  • They discovered orbiting in this big gap, suspiciously big gap, between Mars and Jupiter.
  • People were saying, let's just keep looking.
  • There's got to be something there.
  • It's a bigger gap than you think should be there, given the distances between other planets.
  • Exactly.
  • So they found a series of that.
  • We found a planet!
  • And then they found another one.
  • And then they found another one, and another one.
  • The first four asteroids, Ceres, Pallas, Vesta, and Juno.
  • Ceres is the goddess of harvest, and that's the root to the word cereal.
  • Okay?
  • Yeah, that's cool.
  • There you go.
  • There you go.
  • Okay?
  • So, anyhow, once we started discovering many, many, many more of these, we realized, wait a minute, they're all in the same swath of real estate?
  • They don't sort of own their own space?
  • And actually, they're really tiny.
  • They're so tiny through a telescope, they look like a star.
  • Stars are so far away, you can't see any size for them.
  • These are right here with us.
  • They're right here with us.
  • So they look like stars, but they're not stars.
  • They're asteroids.
  • Well, how many are there?
  • Well, we started counting, hundreds initially, then thousands, then tens of thousands.
  • than hundreds of thousands.
  • Right now, we're up over a million known asteroids with orbits and existence in our solar system.
  • Right.
  • And one of them has my name on it.
  • No.
  • You didn't know that?
  • I did not.
  • You did not know that?
  • I'm serious.
  • I did not.
  • We've been together a long time.
  • How did I not know?
  • You have your own asteroid?
  • Yes, I do.
  • Yes, I do.
  • I'm sorry.
  • I don't mean to brag or anything.
  • By the way, there are a lot of asteroids.
  • So there's a limit to how big your head can get, which you get an asteroid named after you.
  • Just saying.
  • I don't know about that.
  • That's not bad.
  • I mean, I wouldn't mind.
  • I mean, can you see it?
  • Now, that's the thing.
  • Well, I double checked that
  • It's not headed towards Earth, or it's not on an Earth crossing orbit.
  • You don't want to be that asteroid.
  • You don't want to be that asteroid.
  • Yeah, it's just like Neil Tyson is coming to kill you all.
  • So it's asteroid one three, one, two, three, Tyson.
  • One, three, one, two, three, Tyson.
  • Yeah, that's what it is.
  • That's cool, man.
  • OK, so I have a name.
  • Now wait a minute.
  • Just very quickly.
  • What?
  • Can anybody get their own asteroid?
  • Or is that something where somebody bestowed this honor upon you?
  • It's not one of those things where it's just like one of these services where it's just like, you too can name a star.
  • Give it to your girlfriend for Valentine's Day.
  • Name a star.
  • You use the salesman voice, right?
  • Name a star.
  • So the person who discovers the asteroid has the power to name it after any person, place, or thing.
  • Oh, so that's cool.
  • So somebody found this asteroid that you know, and they were just like, hey, Neil, I'm going to name this asteroid.
  • Wow, that I'm going to say.
  • So that's an honor.
  • It's an honor.
  • That's more than an honor.
  • That's like naming a child after somebody.
  • OK.
  • I mean, honestly, that asteroid's going to be there long after we're all gone.
  • Your kid's going to die.
  • That's true.
  • That's true.
  • If you named your kid after me, it'd be like, OK, that's an honor for, like, what, seventy years, three, four, and ten?
  • All right?
  • It's not like your kid's going to live forever.
  • You know, I was named after Chuck Nice.
  • No, but that asteroid will be there for generations to come.
  • Long after I'm dead.
  • That's a serious honor.
  • It is.
  • OK.
  • So that's one of the asteroids in the asteroid belt.
  • Okay, we know of a million, there's probably as many as a billion.
  • Depends on how small you wanna count.
  • All right, so now watch.
  • That swath of real estate is so large.
  • Let's ask the question.
  • What is the average distance between asteroids?
  • Okay.
  • That's a very honest question to ask.
  • That's an honest question, yeah.
  • Now, if you base it on movies, all right.
  • That average distance would be around six and a half feet.
  • That's right, because you're navigating.
  • That's how you got to navigate the spaceship to make it look cool.
  • The spaceship, it doesn't look cool otherwise, right?
  • Yeah.
  • And the rocks are banging off the side of the ship.
  • Exactly.
  • and jostling the ship.
  • Right.
  • And even in Star Trek, well, Captain, we're entering a star, an asteroid field.
  • There they go.
  • And so yeah, this is this is cinematic trope.
  • What's going on as you enter an asteroid field?
  • Okay.
  • I got a feeling right now.
  • I got a feeling that you are about to ruin another cinematic constant or, or, or, uh, a tradition.
  • Another cinematic tradition is about to bite the dust.
  • Courtesy of Neil deGrasse Tyson.
  • Why you got, why do you got billet like that?
  • Why you gotta make me look, why you got, why you, why you do that?
  • Something telling me, man.
  • Okay, the average distance between asteroids in the asteroid belt is about six hundred thousand miles.
  • Oh my God.
  • So basically you're like, okay, so you can't see it, but over there to the left, if we're not careful, in about a month, we might hit that asteroid.
  • Showing that in the movie, right?
  • That's the movie.
  • That's the new movie version, OK?
  • Captain, we've entered the asteroid belt.
  • Oh my god.
  • What is the potential damage, number one?
  • I don't know how to say this, Captain, but we can't see any of them.
  • They're too far away.
  • How shall we maneuver the ship?
  • There's no need to.
  • I'm actually going to go take a nap now, Captain.
  • I'm going to go lay down because...
  • That's how much danger an asteroid belt actually poses.
  • You know?
  • So what's interesting is our first space, we have four, well, five, well, more than that.
  • I'm old enough to remember the first four spaceship to go beyond Mars in the solar system to reach the outer planets.
  • So if you want to go to the outer planets, you have to cross the asteroid belt.
  • Right.
  • Okay?
  • We did this calculation.
  • All right, early on, Pioneer Ten and Eleven, twin spacecraft, first to have enough energy to leave the solar system, but they're not as famous as Voyager One and Two.
  • All four of those spacecraft went through the asteroid belt and nothing happened to them.
  • And if it did, NASA would have been the laughingstock of all space programs ever, because there's six hundred thousand.
  • How could you hit some?
  • You can't.
  • If you tried to hit something, you couldn't hit it.
  • You gotta try.
  • It's like when my dad took me to learn how to drive in the parking lot of the supermarket, and the supermarket is closed, and I hit a lamppost.
  • And he went, how?
  • What?
  • How could you?
  • There's nothing here but lines on the ground and this one lamppost, and you hit it?
  • How did you hit the lamppost?
  • Okay.
  • So yeah, I'm just trying to get real here.
  • I mean, so that's all I'm saying.
  • Oh my God.
  • Yeah, yeah.
  • That's terrible.
  • So that's why we don't worry about crossing the asteroid belt.
  • We just send stuff through.
  • It's not even a thing.
  • Yeah, exactly.
  • Yeah.
  • I mean, honestly.
  • Oh my God.
  • And once again, I can say once again, Star Wars has it completely wrong when it comes to the science of space.
  • Thank you, Star Wars, for your assiduous consistency, where you just get it wrong every time.
  • So anyway, that was a long lead up to that one little bitty fact there.
  • But you learned that I have an asteroid.
  • I have an asteroid named after me.
  • That was so much fun.
  • But actually, and that's the coolest thing.
  • Well, actually, those are two cool things we learned.
  • One, you are never getting hit by an asteroid in the asteroid belt.
  • That's number one.
  • Number one.
  • OK.
  • And number two, Tyson, three, two, one?
  • No.
  • It's one, three, one, two, three, Tyson.
  • One, three, one, two, three, Tyson.
  • Which means, at the time that was named for me,
  • there was in the tens of thousands of named asteroids.
  • But now we're in the high hundreds of thousands getting named.
  • And so there's asteroids named after, like I said, people, places, and things.
  • If you discover enough asteroids, you can name one after your pet.
  • Right, yeah.
  • So there's an asteroid somewhere named Fluffy.
  • Fluffy, three, one, one, two, three.
  • There's an asteroid named Santa.
  • That was kinda cool.
  • And I have a friend of mine who was at a telescope on Christmas Day and he made sure to observe Asteroid Santa on Christmas Day.
  • Just for the grins of it, yeah.
  • That's a cool thing to know, though.
  • Once again, this has been a StarTalk Explainer.
  • This time, how crowded is the asteroid belt?
  • Thanks for being there, Chuck.
  • A pleasure.
  • Neil deGrasse Tyson, as always, keep looking up.
