7 Coldest Planets in the Space

Uranus:  Uranus is the seventh planet from the Sun and is known for its extreme cold temperatures. The average temperature on Uranus is around -224 degrees Celsius (-371 degrees Fahrenheit). It has a frigid atmosphere composed mainly of hydrogen, helium, and methane. 

 Pluto:  Although Pluto was reclassified as a dwarf planet, it is still one of the coldest objects in our solar system. Pluto's average surface temperature can drop as low as -230 degrees Celsius (-382 degrees Fahrenheit) 

Saturn's Moon Titan While not a planet, Saturn's largest moon, Titan, deserves a mention. It has an average temperature of around -179 degrees Celsius (-290 degrees Fahrenheit).  

Saturn's Moon Enceladus Another moon of Saturn, Enceladus, is a frigid world with temperatures averaging around -198 degrees Celsius (-324 degrees Fahrenheit). 

Jupiter's Moon Europa Europa, one of Jupiter's moons, has an average surface temperature of approximately -160 degrees Celsius (-260 degrees Fahrenheit).  

Dwarf Planet Eris Eris is one of the largest known dwarf planets in the Kuiper Belt, a region beyond Neptune. It is extremely cold, with temperatures dropping as low as -240 degrees Celsius (-400 degrees Fahrenheit). 

Neptune -  The second ice giant consecutively placed after Uranus, Neptune is the other blue planet. Galle intended to name it after its predictor, Le Verrier, but the International Astronomical Community disagreed and decided to name it after the Roman god of the sea.
