Neptune is not the hottest planet, Venus is.
The hottest planet is Venus. Then Mercury, Earth, Mars, Jupiter, Saturn, Neptune, Uranus, then if it was still a planet, Pluto. (Uranus has been proven to be colder than Neptune, despite Neptune being further from the sun).
Venus is much closer to the Sun than Neptune and, is the hotter of the two planets.
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.)

It is the coldest planet. If you include the Dwarf Planet Pluto, then Pluto is colder.
Mercury is the hottest planet because it is the closest planet to the sun, and therefore receives more direct sunlight. Neptune is the coldest planet because it is the farthest planet from the sun, receiving very little sunlight and having a thick atmosphere that traps heat, resulting in cold temperatures.
Sixth hottest planet: Saturn (-218 °F, -139 °C) Seventh hottest planet: Neptune (-340 °F, -207 °C) Eight hottest planet: Uranus (-350 °F, -212 °C)
The 3rd hottest planet in our solar system is Venus. Its thick atmosphere traps heat from the Sun, creating a runaway greenhouse effect that makes it the hottest planet with surface temperatures hot enough to melt lead.
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 has an average temperature of -200C, making it the coldest planet in the solar system (at least now that Pluto has been demoted from planetary status).
