Like Uranus, whose magnetic axis is tilted about 60 degrees from the axis of rotation, Neptune's magnetosphere undergoes wild variations during each rotation because of this misalignment.

Astronomers have calculated winds blasting across the surface of Neptune at 2,100 km/hour.Deep down inside Neptune, the planet might have an actual solid surface. The three most impressive were all spotted in 1989 by the The first to be spotted was a massive anticyclonic storm measuring 13,000 x 6,600 km and resembling the For reasons that astronomers are still not clear on, the interior of Neptune is unusually hot. This site is maintained by the Planetary Science Communications team at 10 Need-to-Know Things About Neptune 1 Giant Neptune is about four times wider than Earth. Scientists may have an explanation for a mysterious moon around Neptune that they discovered with Hubble in 2013. The next-generation radiometer is being developed to study the atmospheres of Uranus or Neptune, but could be used to study any atmosphere. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth.

Pluto's highly eccentric, oval-shaped orbit brings it inside Neptune's orbit for a 20-year period every 248 Earth years.

Like Uranus, whose magnetic axis is tilted about 60 degrees from the axis of rotation, Neptune's magnetosphere undergoes wild variations during each rotation because of this misalignment. Triton is extremely cold, with surface temperatures around minus 391 degrees Fahrenheit (minus 235 degrees Celsius). Four prominent arcs named Liberté (Liberty), Egalité (Equality), Fraternité (Fraternity) and Courage are in the outermost ring, Adams. Neptune is one of two ice giants in the outer solar system (the other is Uranus). Most (80 percent 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. In fact, Neptune gives off 2.6 times more energy than it takes in from the Sun. A 3D model of Neptune, an ice giant planet. It's never too late to appreciate the far-reaching influence the Voyagers have had—including pop culture.

A new mission competing for selection under NASA's Discovery Program would try to untangle the mysteries of Neptune's strange moon Triton. So does Neptunes surface looks like hell with melted rock?

Like its neighbor Uranus, Neptune likely formed closer to the Sun and moved to the outer solar system about 4 billion years ago. And we know nothing about the surface of Neptune, if it has one at all.

As you descend into your gas giant of choice, you will notice it getting hotter, and also that the gases you are descending into are starting to feel a bit… liquidy. This image from NASA’s Juno spacecraft captures several storms in Jupiter’s southern hemisphere. For the interior of Jupiter, let's imagine taking a descent from cloud-tops down to the core based on our best guesses of what lies below. !That seems like a bizarre definition of “surface”.
It is made of a thick soup of water, ammonia, and methane flowing over a solid core about the size of Earth.

Neptune has a surface, depending on the temperature it will be solid or liquid.

Does Neptune have a surface? By contrast, the reverse is true for the polar regions where the rotation period is 12 hours.This differential rotation is the most pronounced of any planet in the Solar System, and results in strong latitudinal wind shear and violent storms. Like its neighbor Uranus, Neptune likely formed closer to the Sun and moved to the outer solar system about 4 billion years ago. And yet, despite this deep freeze at Triton, Voyager 2 discovered geysers spewing icy material upward more than 5 miles (8 kilometers). Neptune, like Uranus, is an ice giant, a subclass of giant planet, because they are smaller and have higher concentrations of volatiles than Jupiter and Saturn.

Neptune's largest moon Triton was discovered on October 10, 1846, by William Lassell, just 17 days after Johann Gottfried Galle discovered the planet. Most (80 percent 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. You may be able to help Curiosity rover drivers better navigate Mars using the online tool AI4Mars to label terrain features. Its atmosphere (made up mostly of hydrogen, helium and methane) extends to great depths, gradually merging into water and other melted ices over a heavier, solid core with about the same mass as Earth.Neptune's atmosphere is made up mostly of hydrogen and helium with just a little bit of methane. article last updated October 24, 2019

The only place actually cold is the cloud tops. The magnetic field of Neptune is about 27 times more powerful than that of Earth.​Neptune has 14 known moons. Neptune's equatorial radius of 24,764 km is nearly four times that of Earth. You may be able to help Curiosity rover drivers better navigate Mars using the online tool AI4Mars to label terrain features. These are two enormous planets in our outer solar system: Uranus and Neptune.
Neptune, like all the giant planets in our solar system, is believed not to have a solid (or liquid) surface. Neptune does not have a solid surface. Because Neptune’s atmospheric methane content is similar to that of Uranus, some unknown atmospheric constituent is thought to contribute to Neptune’s more intense coloring.Also like Uranus, Neptune’s internal structure is differentiated between a rocky core consisting of silicates and metals; a mantle consisting of water, ammonia and methane ices; and an atmosphere consisting of hydrogen, helium and methane gas. In all cases though, that “surface” is too far from the upper layers to fit the name.And scientists use Earth’s standard (1 bar at the surface) because air pressure ranges wildly on the other terrestrial planets, from virtually none at all to 92 times that of Earth. Neptune is very similar to Uranus.
