The term that refers to celestial objects that resemble large chunks of rock and debris is asteroids.

Here's why:

* Asteroids are rocky, airless celestial bodies that orbit the Sun, mainly found in the asteroid belt between Mars and Jupiter. They are generally smaller than planets, ranging in size from a few meters to hundreds of kilometers in diameter.

* Comets are icy bodies that orbit the Sun and release gas and dust as they get closer, creating a visible tail.

* Meteors are small pieces of rock or dust that burn up in the Earth's atmosphere, creating a streak of light.

While asteroids can resemble large chunks of rock and debris, they are technically celestial bodies with specific characteristics and orbits.
