Orbit, Solar, Immense | Vocabulary

0:00- [Narrator] Wordsmiths, hello and welcome to the "KAS Bookworm," Khan Academy's newest and most delightful invention. It's a space station and I'm spending the week up here keeping an eye out for cool space things like meteors, comets, visits from alien neighbors, stuff like that.

0:17It's an immense job keeping this baby in orbit. But we've got everything we need on the "Bookworm," probably the nicest space station in the whole solar system. And those are our words for this video too. Orbit, solar and immense. I'm gonna go through these words, show you how they're used and what they mean, and then put them to work in a few sentences.

0:40Orbit. Orbit. It's a verb and a noun. As a verb, it means to move in a rounded path around an object. The moon orbits the earth, right? But as a noun, it means the rounded path of one object in space around a larger object. So we can talk about the moon's orbit as a noun, as a thing.

1:03Solar. Solar. It's an adjective, a describing word. It means having to do with the sun. So I said before, this is the nicest space station in the whole solar system, right? The system of planets and moons and asteroids that orbit our sun. The solar system. Finally, immense. Immense.

1:28It's another adjective and it means very large. Like huge. The Sahara desert is immense. The planet Jupiter is immense and the sun is immense compared to Jupiter. The thing to remember is that immense means really, really big. Let's use these words in some sentences.

1:49The earth orbits the sun in much the same way as my favorite ice cream truck orbits my neighborhood. The truck drives in circles around my neighborhood, much like the earth moves in a rounded path around the sun. The difference being that the earth doesn't drive.

2:04It's old enough to have a license, but it simply chose not to get one. And I respect that. Also, this is not where I actually live. Nice try. Next sentence. Our school has big solar panels on the roof. So now we get power from the sun. Solar has to do with the sun. So what does a solar panel do?

2:21It gets energy or power from the sun. It turns sunlight into electricity that we can use to keep the lights and the air conditioning and all the computers running. Last one, the alien spaceship was immense. It was easily the size of a skyscraper. It's so big we can barely make sense of it.

2:42Huge on an impossible scale. I mean, this space station is big, like maybe the size of a football field, but we're not putting things in space much larger than than that. Okay. Wow, that's a big spaceship. That is a big alien spaceship. Hey, wordsmiths, I have to go.

3:03I think I have to call my boss or maybe NASA or the president. Until the next one, you can learn anything. David out.
