How is Neptune different from Earth?
Neptune has 17 times as much mass compared to the Earth. The surface gravity on Neptune (if it actually had a surface that you could stand on) is only 14% stronger than the pull of gravity on Earth. You would have a difficult time noticing if you were standing on the surface of Neptune compared to the surface of Earth.
What is the specific composition of Neptune?
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.
What is the composition of Neptune’s atmosphere?
Neptune’s thick atmosphere is mostly hydrogen, with smaller amounts of helium and methane. It is the absorption of red light by methane which gives Neptune its very blue coloration. The average temperature on Neptune is a brutally cold -373 degrees F.
Why can humans not live on Neptune?
Although there is a lot of gas surrounding Neptune (its atmosphere), the planet itself is largely made up of ice and doesn’t have a solid surface for us to stand on. So, this is one major reason that humans could not live on the planet Neptune.

How does Neptune affect Earth?
Yet, the small amount of sunlight Neptune does receive significantly affects the planet’s atmosphere. The astronomers found that these temperature variations are consistent with seasonal changes. A Neptunian year lasts about 165 Earth years.
What is the composition of the planet Uranus?
Uranus is made of water, methane, and ammonia fluids above a small rocky center. Its atmosphere is made of hydrogen and helium like Jupiter and Saturn, but it also has methane. The methane makes Uranus blue.
Can we walk on Neptune?
Deep down inside Neptune, the planet might have an actual solid surface. At the very core of the gas/ice giant is thought to be a region of rock with roughly the mass of the Earth. In short, there is simply no way one could stand on the “surface of Neptune”, let alone walk around on it.
What would happen if you jumped into Jupiter?
Jupiter’s deep atmosphere absorbs radio waves, so you’ll be shut off from the outside world— unable to communicate. Once you’ve reached 2,500 miles down, the temperature is 6,100 ºF. That’s hot enough to melt tungsten, the metal with the highest melting point in the Universe.
