Neptune is our solar system's windiest world. Despite its great distance and low energy input from the Sun, Neptune's winds can be three times stronger than Jupiter's and nine times stronger than Earth's. These winds whip clouds of frozen methane across the planet at speeds of more than 1,200 miles per hour (2,000 kilometers per hour).

Neptune is one of two ice giants in the outer solar system (the other is Uranus). Most (80% or more) of the planet's mass is made up of a hot dense fluid of "icy" materials – water, methane, and ammonia – above a small, rocky core. Of the giant planets, Neptune is the densest. Scientists think there might be an ocean of super hot water ...
Neptune is the eighth and farthest known planet from the Sun. It is the fourth-largest planet in the Solar System by diameter, the third-most-massive planet, and the densest giant planet. It is 17 times the mass of Earth. Compared to its fellow ice giant Uranus, Neptune is slightly more massive, but denser and smaller.
Mar 28, 2019 · Neptune is the windiest planet in our solar system, whipping up momentous gusts that can reach more than 1,200 miles an hour. That soothing sapphire expanse does reveal some of the whirling chaos ...
- Why is Neptune blue? The planet's cloud cover has an especially vivid blue tint that is partly due to an as-yet-unidentified compound and the result of the absorption of red light by methane in the planet's mostly hydrogen-helium atmosphere.
- Neptune FAQs answered by an expert. We asked planetary scientist Dr Michael Roman a few frequently asked questions about Neptune. Dr Michael Roman. Dr Michael Roman is an expert on the giant planets of the solar system.
- Does Neptune have rings? Neptune is surrounded by unusual rings, which aren't uniform but possess bright thick clumps of dust called arcs. There are at least 5 rings around Neptune — called Galle, Leverrier, Lassell, Arago, and Adams — and they are considered relatively young and short-lived.
- Neptune by the numbers. Atmospheric composition (by volume): 80% hydrogen, 19% helium, 1.5% methane. Magnetic field: Roughly 27 times more powerful than Earth's.
Neptune was the first planet located using math. German astronomer Johann Galle was the first to observe the planet in 1846. The planet is named after the Roman god of the sea. Get the Facts. This picture of Neptune was produced from images taken by NASA’s Voyager 2 in the summer of 1989 as it became the first spacecraft to fly by the planet.
