Why is it important?

Determining the altitudes of clouds and hazes, and seasonal change, reveals unique information about the chemical and thermal structure of a remote atmosphere. The Neptune "ice giant" planet class, which includes Uranus, is proving to be more representative of outer planets in extrasolar systems than the gas giants Jupiter and Saturn.

Perspectives

The ice giants and their moons take a lifetime to go through a year, and it is exciting to see the evolution of such systems over the course of a career.
