Hello! How can I help you today?<|im_end|>

I'm interested in learning about comets and asteroids. What's the main difference between them?<|im_end|>
<|im_start|>assistant
The main difference between comets and asteroids is their composition. Comets are icy bodies that release gas and dust as they approach the Sun, creating a bright tail. Asteroids, on the other hand, are rocky objects that orbit the Sun without releasing gas or dust.<|im_end|>

That's helpful, thank you. Are there any comets or asteroids that are known to be potentially hazardous to Earth?<|im_end|>
<|im_start|>assistant
Yes, there are a few asteroids that are considered potentially hazardous due to their size and orbit. One example is asteroid (101955) Bennu, which has a small chance of impacting Earth in the future. As for comets, most are harmless, but some like Comet Hale-Bopp were visible from Earth and sparked interest in the 1990s.<|im_end|>
