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 ...
Subsolar temperature [61] Ganymede: 156 K Subsolar temperature [61] 80 K Nighttime temperature [62] Callisto: 168 K Subsolar temperature [61] 80 K Predawn nighttime temperature [63] Titan: 2 km (1.2 mi) Mithrim Montes, Xanadu [64] Mimas: Enceladus: 110 K Tiger Stripes [65] Tethys: Dione: Rhea: Iapetus: 20 kilometres (12 mi)Voyager Mountains ...
Earth has an albedo of about 0.306 and a solar irradiance (L / 4 π D 2) of 1361 W m −2 at its mean orbital radius of 1.5×10 8 km. The calculation with ε=1 and remaining physical constants then gives an Earth effective temperature of 254 K (−19 °C). [11] The actual temperature of Earth's surface is an average 288 K (15 °C) as of 2020. [12]
Satellite measurements of the surface temperature of Antarctica, taken between 1982 and 2013, found a coldest temperature of −93.2 °C (−135.8 °F) on 10 August 2010, at Although this is not comparable to an air temperature, it is believed that the air temperature at this location would have been lower than the official record lowest air ...
