You are gravely mistaken. Neptune is not a hot planet and it never has been. Neptune is so far from the sun that the planet and its atmosphere are absolutely freezing. The average temperature of Neptune is −218 °C (55.1 K).
No, the dark side of the planets temperature averages 110 K. which is much hotter then the mean surface temperature of say Neptune at 72K.
The average temperature of Neptune is -200 degrees Celsius
The mean atmospheric temperature on Neptune is as low as -218°C at the cloud tops and about 72° K or -200° C at the pressure level equal to 1 Earth atmosphere.
The surface temperature on Neptune is very very cold. it is - 391 F.
The average temperature on Neptune is about -214°C, while Mars has an average temperature of around -63°C. To find the net change in temperature from Neptune to Mars, subtract Mars' temperature from Neptune's: -63°C - (-214°C) = 151°C. Thus, the net change in temperature from Neptune to Mars is approximately 151 degrees Celsius.
it - 200 degrees celsius it - 200 degrees celsius
Neptune −201 °C. Uranus −197.2 °C.
The planet with the lowest average temperature in our solar system is Neptune. Its temperature can drop as low as -360°F (-218°C).
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).
The average temperature of Neptune is -200 degrees Celsius (C), which is -328 degrees Fahrenheit (F). However, Neptune's temperature can dip down to -218 degrees Celsius, which is -360 degrees Fahrenheit.
The average temperature on Neptune is -353°F (-214°C)
