Uranus: Physical Mechanisms

Uranus is an ice giant with a small hydrogen-helium atmosphere above an interior rich in water, ammonia, methane, and rock. Uranus tests models of ice-giant interiors, unusual magnetic dynamos, giant impacts, seasonal atmospheric response, and exoplanet classes because Neptune-sized worlds are common around other stars.
