90337 Sedna is a distant trans-Neptunian object in the outer solar system, and while its exact composition is not fully known, it is believed to contain a mixture of rock and ice. Spectroscopic observations suggest the presence of organic compounds and possibly tholins, which are complex organic molecules formed under ultraviolet light. Its surface is likely covered in a layer of frozen methane, nitrogen, and possibly other ices. However, due to its great distance, detailed studies of Sedna's composition are limited.
