No, but there is PLENTY of lightning.
No. Neptune's atmosphere is almost entirely hydrogen and helium with small amounts of methane. There is no oxygen.
The Earth is not the closest planet to the sun and it is generally agreed it gets enough light. Neptune however gets a negligible amount of light from the sun, which at Neptune's distance just looks like a bright star.
They aren't transparent. They don't get enough light and they are hard to see, but they are there.
If it is at a high enough frequency, yes.
No humans have visited the planet Neptune.
No, humans could not live on Neptune. Neptune's extreme cold temperatures, high wind speeds, and lack of a solid surface make it inhospitable to humans. Additionally, the planet's atmosphere is mainly composed of hydrogen and helium, which are not breathable for humans.
No, it is not possible to ignite Neptune to create a small sun. Neptune is a gas giant planet, primarily made of hydrogen and helium, while a sun is a massive star that undergoes nuclear fusion producing light and heat. The size and composition of Neptune are not conducive to creating a star.
Neptune is a gas giant, so it is uninhabitable to humans.
No, humans have not been to Neptune and there are no known pie vendors on the planet. Additionally, the extreme conditions on Neptune would make it impossible for humans to survive without special equipment.
An object that orbits Neptune would be called a MOON of Neptune, if it is large enough.
no because planet neptune does not have enough atmosphere for human to breath in
Yes, Neptune's atmosphere is composed mostly of hydrogen, helium, and methane gases. The methane in the atmosphere absorbs red light, giving Neptune its cyan color. The concentration of methane in the atmosphere makes it toxic to humans.
