Neptune has a fairly constant temperature of 72 degrees Kelvin. 200 c
Technically speaking, Neptune is the planet with the lowest surface temperature; however, Neptune does not have a solid surface.
Neptune is expected to have the lowest surface temperature among Uranus, Saturn, and Neptune. This is due to Neptune's farther distance from the sun compared to Uranus and Saturn, resulting in less solar energy reaching its atmosphere.
The planet with the lowest average temperature in our solar system is Neptune. Its temperature can drop as low as -360°F (-218°C).
Farthest from Sun
Neptune(If you include dwarf planets it is Eris)

Neptune's moon Triton has the lowest recorded temperature of any moon.
The moon that is the farthest from the Sun. Triton, a moon of Neptune, has the lowest temperature so far measured.
Neptune
The average temperature of Neptune is -200 degrees Celsius
The surface temperature on Neptune is very very cold. it is - 391 F.
Venus has the highest average surface temperature due to its thick atmosphere that traps heat, creating a greenhouse effect. Neptune has the lowest average surface temperature, being the farthest planet from the Sun and having a frigid atmosphere.
Pluto is not the lowest temperature. The lowest temperature possible is −273.15°C. Pluto's coldest temperature is about −233°C.
