0-degrees Kelvin corresponds to -273-degrees Celsius. The surface of Pluto, in comparison, can range from a low temperature of 33 Kelvin (-240 degrees Celsius or -400 degrees Fahrenheit) and 55 Kelvin (-218 degrees Celsius or -360 degrees Fahrenheit). The average surface temperature on Pluto is 44 Kelvin (-229 Celsius or -380 Fahrenheit). Back in the days when Pluto was still a planet, it was the coldest planet in the Solar System. But now itâs just a regular temperature dwarf plant â poor Pluto. Neptune is now the coldest planet.
Receiving less sunlight, the gas would condense onto the surface.. Mars, whose orbit is also rather elliptical, temporarily loses a quarter of its air every time its southern hemisphere experiences winter, when Martian gas freezes onto the south polar cap. Pluto is mostly rock, but its crust consists of water ice. At Pluto's temperature of approximately 40 kelvins (â233 Celsius), water is as hard as rock, constituting a stage on which nitrogen and also methane dance back and forth between ice and gas.
