Why Neptune temperature so high is and why Neptune has the lowest temperature compared to other planets and why are Uranus and Neptune the same temperature?
Neptune is the coldest planet in the Solar System because it is the farthest from the Sun. The temperature of the planet Neptune reaches -221°C. Neptune belongs to the group of gas giants, and its size is slightly smaller than that of Uranus. However, the distance to Neptune from the sun is enormous on average; the planet is 2.8 billion miles (4.5 billion kilometers) from the heat-giving star. The pole tipped toward the sun reaches higher temperatures than the rest of the planet for a quarter of a Neptunian year, or for about 40 Earth-years. The Uranus and Neptune have the same atmospheric conditions. Both planets' atmospheres are predominantly made up of hydrogen, helium and methane gases. They are roughly the same temperature. The average temperature on Neptune is -214°C, while it's a chilly -216°C on Uranus.

I don't think that ResearchGate was meant to be a theatre for people to display their ability to copy other people's work.
