Because of its great distance from the Sun, Neptune's outer atmosphere is one of the coldest places in the Solar System, with temperatures at its cloud tops approaching 55 K (−218 °C; −361 °F). Temperatures at the planet's centre are approximately 5,400 K (5,100 °C; 9,300 °F).
The temperature of Triton's upper atmosphere, at 95 ± 5 K, is higher than that at its surface, due to heat absorbed from solar radiation and Neptune's magnetosphere. [ 48 ] [ 53 ] A haze permeates most of Triton's troposphere, thought to be composed largely of hydrocarbons and nitriles created by the action of sunlight on methane.

This is a list of the coolest exoplanets known, specifically those with temperatures lower than −75 °C (198 K). Planets from the Solar System were also included for comparison purposes. Discovered in 2006, OGLE-2005-BLG-390Lb is the coldest known exoplanet, and was nicknamed "Hoth" by NASA in reference to the planet from the Star Wars ...
Aerial photograph of Vostok Station, the coldest directly observed location on Earth. The location of Vostok Station in Antarctica. The lowest natural temperature ever directly recorded at ground level on Earth is −89.2 °C (−128.6 °F; 184.0 K) at the then-Soviet Vostok Station in Antarctica on 21 July 1983 by ground measurements.
Neptune was discovered in 1846 and is located 30 times farther from the sun than Earth. The planet's 164-year orbit takes it through some of the darkest and most remote regions of the outer solar ...
Imagine a town so cold that low temperatures in the -60s are considered, well, "normal", in the winter months. Yes, you read that right, minus 60s! The mere mention of "Siberia" is synonymous with ...
Neptune's outermost moon S/2021 N 1, ... Triton is one of the coldest bodies in the Solar System, with a surface temperature of about 38 K (−235.2 °C). ...
