When we're identifying exoplanets, we generally put them into different categories based on the planets in our solar system. We can identify them by size, in which case we use thse names; rocky planets; super-Earths; mini-Neptunes; ice giants; and gas giants. We also refer to exoplanets by their distance from the star, with names Hot Jupiter and Hot Neptune for those closer, and Cold Jupiter and Cold Neptune for those further away.
