Here's why:

* Meteors are extraterrestrial objects: Planetary scientists specialize in the study of planets, moons, asteroids, comets, and other celestial bodies. Meteors are essentially small pieces of these objects that enter Earth's atmosphere.

* Composition and origin: Planetary scientists are equipped to analyze the composition of meteors to understand their origins and the conditions in the solar system when they formed.

* Impact studies: Planetary scientists also study the effects of meteorite impacts on Earth and other planets, helping us understand the history of our solar system and potential hazards.

While other scientists might contribute to meteor research, planetary scientists are the primary experts in this field.
