Dec 14, 2012 · Neptune's atmosphere is made up predominately of hydrogen and helium, with some methane. The methane is part of what gives Neptune its brilliant blue tint, as it absorbs red light and...

Nov 6, 2024 · Atmosphere. Neptune’s atmosphere is made up mostly of hydrogen and helium with just a little bit of methane. Neptune’s neighbor Uranus has a similar makeup; the methane absorbs other colors but reflects blue, giving these ice giants their similar hue.

Like Jupiter and Saturn, Neptune’s atmosphere consists mostly of hydrogen and helium, but it also has methane that absorbs red light, giving it a deep blue hue. Beneath the atmosphere lies an ocean of water, ammonia, and methane, squeezed by intense pressures into a …

In high altitudes, the atmosphere in Neptune is composed of 80% hydrogen and 19% helium with a small amount of methane. At wavelengths above 600 nm, absorption of bands of methane occurs in the red to infrared parts of the spectrum.

Because of its great distance from the Sun, Neptune's outer atmosphere is one of the coldest places in the Solar System, with temperatures at its cloud tops approaching 55 K (−218 °C; −361 °F). Temperatures at the planet's centre are approximately 5,400 K (5,100 °C; 9,300 °F).

Oct 3, 2024 · Surface Pressure: >>1000 bars Temperature at 1 bar: 72 K (-201 C) Temperature at 0.1 bar: 55 K (-218 C) Density at 1 bar: 0.45 kg/m 3 Wind speeds: 0-580 m/s Scale height: 19.1 - 20.3 km Mean molecular weight: 2.53 - 2.69 Atmospheric composition (by volume, uncertainty in parentheses) Major: Molecular hydrogen (H 2) - 80.0% (3.2%); Helium (He) -...

Nov 27, 2008 · The atmosphere of Neptune is similar to all the large planets in the Solar System; it mostly consists of hydrogen and helium, with trace amounts of methane, water, ammonia and other ices.

Oct 15, 2021 · The eighth and last planet in the solar system, Neptune has an atmosphere more comparable with Uranus than with Saturn and Jupiter. The two most distant planets boast atmospheres dominated by ices. But even with a chill in the air, Neptune still manages to host some of the most extreme and violent weather in the solar system.

The atmosphere of Neptune is very similar to that of Uranus, and unlike that of Saturn and Jupiter. On Jupiter and Saturn, the atmosphere is mostly composed of the simple molecules hydrogen and helium.

At high altitudes, Neptune's atmosphere is 80% hydrogen and 19% helium. A trace amount of methane is also present. Prominent features of Neptune include its bright blue color, the Great Dark Spot, and its thin cloud streaks.
