Did you know that a meteoroid is smaller than an asteroid?

Really? I always thought they were the same thing.

Nope! A meteoroid is basically just a tiny rock in space.

That's interesting! So, what happens when they enter the atmosphere?

Root Explanation

Meteoroid → It is formed from "meteor" (from Greek "meteōros", meaning high in the air) and the suffix "-oid" (meaning resembling or like). The word "meteoroid" refers to a small body that resembles a meteor, typically found in space.

Memory Tip

Think of something that is 'high in the air' ('meteōros') and 'resembles' something else ('-oid'). This helps you remember that a meteoroid is a small object that looks like a meteor.
