It is not going to hit the Earth. I don't know the exact probability, but we are confident the Earth is in the clear.

We're continuing to measure it. 2% chance of hitting the moon, that could go up. It could go down. Obviously, as the statistician said, it's a 98% chance or so that it won't hit. We'll see where that number goes.

How big is this one? It's about 60 meters across. So it's the size of maybe a 15 or 20 story building. So it's small compared to things like Jupiter or a lot of the things that we talk about in astronomy. It's human scale. You can imagine how big it is.

Those are more like a kilometre across. And then the one that we think did in the dinosaurs was more like 10. 10 kilometres.

People have been studying the paths of the planets and things in the sky for literally thousands of years. And the math involved in doing it is hundreds of years old. And we have these amazing... telescopes that can give us this great data that we can feed into those numbers.
