i think 184 degrees Celsius
The hottest (surface temperature) is Venus then, getting colder: Mercury, Earth, Mars, Jupiter, Saturn, Neptune and Uranus. (In fact Neptune and Uranus are very similar in temperature.)
The average temperature on Neptune is -353°F (-214°C)

The surface temperature on Neptune is very very cold. it is - 391 F.
The direct answer to the question is: No.Mercury is the closest planet to the sun, but Venus is the one with thehighest surface temperature, and Neptune is the one with the lowest.
Neptune is not the hottest planet, Venus is.
Technically speaking, Neptune is the planet with the lowest surface temperature; however, Neptune does not have a solid surface.
Venus is hottest. Next is Mercury.
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.
Earth.
The average surface temperature is 72 K.
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.
