What else can I help you with?
Does Neptune receive sunlight?
Yes and no. Neptune gets very little sunlight because it is so far from the sun. When light does reach Neptune, the red spectrum of the dim sunlight is absorbed my the methane atmosphere and the blue light spectrum is reflected off the methane, which gives the planet its blue colour.
How much sunlight is absorbed by Neptune compared with the amount of sunlight absorbed by Earth?
Neptune is 30 times further from the Sun than Earth, so the fraction of sunlight it receives compared to the Earth is the square of that, so 1/900th as much. However, that is comparable with your living room in the evening with the lights turned on. It is still hundreds of times brighter than the full moon - enough to see in full colour. However, beneath the clouds there will be less light of course - it would very much be a twilit world.
Could humans live on Neptune if not why?
No. Humans could not live on Neptune. The planet is extremely cold, its atmosphere is not breathable, and there is no solid surface to stand on. Although in the distant future we could see a space station in orbit around Neptune which would send probes, and ships into the atmosphere for scientific study.
Neptune can only be seen with a what?
You can see Neptune with a telescope.
Which planet would be difficult to see from earth?
Probably Mercury, since you would have to be looking in the direction of the Sun, the overwhelming glare of which makes it almost impossible to see anything else in that direction. Or, it could be Neptune. You can't see Neptune without a telescope.
How did astronomers know Neptune existed before they could see it?
Astronomers knew that Neptune existed before they could see it because they observed that the other planets orbited the sun in a way that could only be explained if they were being influenced by the gravity of another object of such mass. So the astronomers contemplated that there must be another planet somewhere that was changing the orbits of other planets. That planet is today called Neptune.
Can you see the planet Neptune with the naked eye from earth?
You could see Neptune from Earth with a telescope if you knew exactly where to look.

Why is Neptune dark blue?
Neptune appears dark blue due to the presence of methane in its atmosphere. Methane absorbs red light, which makes the planet reflect blue light, giving it its distinctive color. The combination of methane and other gases in Neptune's atmosphere interact with sunlight to create the blue hue that we see.
Do you see the sun in the tundra?
Yes. The tundra does get sunlight. Nothing could grow there otherwise.
Will a meteor burn up in Neptune's atmosphere?
Probably, and depending on its size. Even though Neptune's atmosphere is quite cold, anything hitting it at orbital velocity should cause it to heat up to incandescence, and it could easily burn up. We don't know if Neptune even HAS a "surface", so it's possible that remnants of the meteor could sink into whatever it is that Neptune has in there. Neptune is so far away that no Earth-based telescope could hope to see a Neptunian meteor, but there is no reason to think it wouldn't happen.
Can you see the sun from neptune?
Yes, the Sun can be seen from Neptune, as it is the farthest planet in our solar system. However, due to Neptune's distance from the Sun and the thick atmosphere, the sunlight would be much dimmer and appear as a bright dot in the sky.
