You're welcome.

Pluto is mainly composed of rock and ice. To find this information, you can refer to scientific studies and observations conducted on Pluto. These studies include remote sensing data collected by telescopes and spacecraft, particularly the New Horizons mission that flew by Pluto in 2015. These observations have revealed that Pluto's surface is made up of a mixture of water ice, nitrogen ice, and methane ice, as well as rocky materials. This information is obtained by analyzing the spectral signatures of different compounds on Pluto's surface.
