Overview
Advanced planetary view of Neptune
Neptune is the outermost major planet and an ice giant with a hydrogen-helium-methane atmosphere, strong internal heat flow, high-speed winds, dark storm systems, narrow rings, and an unusually tilted magnetic field. Despite receiving little sunlight, its atmosphere is highly dynamic.
Neptune is a benchmark for ice-giant atmospheric dynamics, internal heat transport, magnetic-field generation, and captured-moon evolution. Its properties are especially important because many discovered exoplanets have radii comparable to Uranus and Neptune.
