- PhilLv 61 month agoFavourite answer
again, Pluto is not a " planet" it is a " dwarf planet".
The coolest planet in our solar System is Neptune if you are just counting the surface temperature which is minus 360 degrees F.
However at it's core it is the hottest planet .
At its core, Neptune reaches temperatures of up to almost 13,000 degrees F which is comparable to the surface of the Sun.
ps, However, since you did mention Pluto, the surface temperature is minus 390 degrees F which is colder than Neptune. A few other dwarf planets exist that are even colder than Pluto ; Eris, Makemake and Haumea , all about minus 402 degrees F to minus 406 degrees F.

Pluto isn't a planet. The coolest is Uranus - oddly enough, Neptune is slightly warmer.

My all time favourite has to be Saturn
For absolute cold it is Uranus which is colder even than Pluto
The Intergalactic Space between the Stars does not even get down to Absolute Zero because of Radiation given off by Stars
But the Cosmic Background Radiation is 2.725 Kelvin
Hydrogen Freezes at 0 KelvinSource(s): Lord Kelvin, One cool Dude !

Uranus is actually the coldest planet. It's atmosphere has a minimum temperature of -224C. Colder than that of Neptune or Pluto

Uranus because it is unlike any of the other planets. The pinkish colour of the one pole we see looks like a giant eyeball considering the rest of the planet appears to be a turquoise shade, it's tilt is about 98 degrees.

Mercury, because there are craters which never see the Sun and during the night it falls to a very low temperature.

Pluto is not a planet anymore.I was gonna say Ur anus was the coolest but i changed my mind. I'd say Neptune is the coolest planet.
