Hello and welcome along, Explorer. It's time for you and me to search through the solar system.

My name's Dan. This is a brand new Fun Kids Science midweekly. And it's a question special.

If you ever have anything science that you floating around your brain like a loose meteor just drifting past Pluto,

then send over to me as a voice note on the free Fun Kids app.

You can do it at FunKidsLive.com 2.

That way I can see it.

You can star in the show and I can do all the digging.

First up, let's get one of those in.

This is a question sent in by Aaron.

Hello, Dan. My name is Aaron, and I would like to know how fast do you need to go to burn up. Thank you.

Hey, Aaron, how fast do you need to go to burn up? I reckon you mean by burning up when something

enters Earth's atmosphere so fast that all the particles rushing past it, bump into it,

they make it get so hot it falls apart, you know, like a meteor, like an asteroid,

traveling through our atmosphere. It kind of burns up. It glows, doesn't it?

Well, that's burning up, and you need to be traveling above really 25,000 miles an hour to burn up.

That's on average, but it depends how small or how big you are, how much there is to break up.

25,000 miles an hour, that's actually Earth escape speed. Anyone or anything traveling at that speed

can escape Earth's gravity. That's how fast you need to move away, really. A plane goes at about

600 miles an hour. That's not nearly fast enough. Some big objects like falling satellites and

space debris, they can burn up a bit over 15,000 miles an hour.

So yeah, different objects need different speeds before they might start to fall apart bit by bit.

Others travelling at seven miles a second, a second might completely vaporise.
