* Meteor: A meteor is the *streak of light* we see when a small piece of space debris (a meteoroid) burns up in Earth's atmosphere. Speed is key: Meteors can be incredibly fast, reaching speeds of tens of thousands of miles per hour.

* Asteroid: An asteroid is a rocky object in space. Some asteroids can have orbits that bring them close to Earth. Speed depends on the orbit: An asteroid's speed varies greatly based on its orbit. Some might be relatively slow, while others can be quite fast.

* Comet: Comets are icy bodies that vaporize when they get close to the Sun, creating a glowing tail. Speed is affected by the Sun: Comets speed up as they get closer to the Sun and slow down as they move away.

So, which is slower? It's impossible to say definitively without knowing the specific objects and their orbits.

Here's why:

* A slow-moving asteroid could be slower than a fast-moving comet.

* A meteoroid burning up in the atmosphere is only considered a meteor during that brief event.
