You're describing meteors, also known as shooting stars. Here's a breakdown:

* Meteoroid: A small rocky or metallic body in space. They can range in size from a grain of sand to a boulder.

* Meteor: When a meteoroid enters the Earth's atmosphere, it heats up due to friction with the air, causing it to glow brightly and create a streak of light. This is what we call a shooting star.

* Meteorite: If a meteoroid survives the fiery descent and reaches the Earth's surface, it's called a meteorite.

So, the objects themselves are meteoroids, the streaks of light are meteors, and the pieces that land on Earth are meteorites.
