Your spaceship.
Neptune takes the longest to revolve around the sun.
Neptune was discovered in 1846 through observations of Uranus. Uranus' orbit was seen to appear to alter slightly through the gravitational effect of another planet, which turned out to be Neptune.
Neptune and Uranus both have high concentrations of methane in their atmospheres.
I believe that Neptune has this axial rotation period.
Neptune is the eighth and furthest planet from the Sun.
Your spaceship.
you should pack lighly and lots of water. :)
yo no sepo
Nothing
Uranus if you're going by mass, Neptune if you're going by radius/volume.
It depends on where you're going.
It really depends on where you're going
most likely a jacket.
Bug spray, water, light clothing.....
There is no mail man going to Neptune!
maybe you should bring an extra air tank and a really warm spacesuit because it can get so cold on neptune. :)
