Neptune's mass of 1.0243×10 kg is intermediate between Earth and the larger gas giants: it is 17 times that of Earth but just 1/19th that of Jupiter. Its gravity at 1 bar is 11.15 m/s , 1.14 times the surface gravity of Earth, and surpassed only by Jupiter. Neptune's equatorial radius of 24,764 km is nearly four times that of Earth. Neptune, like Uranus, is an ice giant, a subclass of giant planet, because the… NettetNeptune is the only giant planet to display cloud shadows cast by high dispersed clouds on a lower, more continuous cloud bank. The higher clouds, probably composed of methane ice crystals, are generally located 50–100 km (30–60 miles) above the main cloud deck, which may be composed of ice crystals of ammonia or hydrogen sulfide.Like the …

Nettet17. mai 2024 · Sub-Neptune planets are the most common type of exoplanets that we know of so far, and scientists studying these planets hypothesize that many of them may have a thick water-rich layer with a rocky interior. This new study suggests that the deep oceans of these exoplanets would be much different from Earth’s ocean and may be … NettetNeptune has an incredibly thick atmosphere comprised of 74% hydrogen, 25% helium and approximately 1% methane. Its atmosphere also contains icy clouds and the fastest winds recorded in the solar system. Particles of icy methane and minor gases in the extremities of the atmosphere give Neptune its deep blue colour.
