What is Neptune highest temperatures?

Answer 1

Neptune does not have a "surface" on which to measure temperature. Its gaseous atmosphere gives way to a dense, hot slush of water and ammonia molecules. So while the outer cloud layers are very cold (-218 to -221°C), the interior is much hotter, up to 5000 to 7000°C near the core.

At the point at which the pressure is equal to sea level on Earth, the temperature is only about -200°C (-328°F).

Answer 2

The mean atmospheric temperature on Neptune is as low as −218 °C (55.1 K) at the cloud tops and about -200 °C (72 K) at the pressure level equal to 1 Earth atmosphere.

The lowest observed temperature within the atmosphere is about -221°C (51.8 K). Probably something like -210 degrees celcius but no one knows the exact temperature.

This is a monstrously difficult question because Neptune is composed mostly of gas with a small core of rock.

It has been estimated that the temperature in the core is on the order of 7,000 °C, which is comparable to Earth's core or the surface of the Sun.

The mean atmospheric temperature on Neptune is as low as 218 °C (55.1 K) at the cloud tops and about -200 °C (72 K) at the pressure level equal to 1 Earth atmosphere.

Compare this to Uranus, which is a bit smaller but is closer to the sun. Uranus is a chilly -224 °C (49 K). Neptune is a long, long way from the sun, and very little energy gets there. But because it is as "warm" as it is, it is thought to have a core that is still generating heat.

That leaves us to make calculations and make an assessment as to why things are as we see them. We can figure out the amount of light Neptune gets, look at how much is reflected and how much is absorbed, and then look at its temperature. Some "extra heat" must be coming from somewhere, and the core is thought to be generating it. We really can't come up with a "surface temperature" per se for Neptune because of its structure. Wikipedia has more information, including a cutaway drawing of Neptune so you can see "into" this gas giant.

Answer 4

Neptune's temperature at its cloud tops is usually close to −218 °C (55.1 K), one of the coldest in the solar system, due to its great distance from the Sun. The temperature in Neptune's centre is about 7,000 °C (7,270 K), which is comparable to the Sun's surface and similar to most other known planets.
