A chunk of rock from space that has entered Earth's atmosphere is called a meteor.

Here's a breakdown of the terms:

* Meteoroid: A chunk of rock or dust in space.

* Meteor: The bright streak of light we see when a meteoroid enters Earth's atmosphere and burns up. This is often called a "shooting star."

* Meteorite: A meteoroid that survives its fiery journey through the atmosphere and lands on Earth's surface.
