All of the gas giants (Jupiter, Saturn, Uranus and Neptune) radiate more heat than they receive.
Neptune. It is the farthest planet from the sun
Because Neptune does have a heat source. It generates about 2.6 times more energy that it receives from the Sun. This may be due to radiogenic heating [See related link] but we're not too sure.
Because Uranus's internal heat is lower than Neptune's -- possibly because it doesn't have a moon as large as Triton providing friction from gravitational drag -- Uranus is actually colder than Neptune, despite being almost a billion miles closer to the sun.
Neptune is very cold on the outside, but deep inside the planet, it's hot! The pressure at the core of Neptune is several million times greater than the pressure at Earths surface.Neptune's core is hotter than the sun. The heat inside Neptune supplies energy for strong winds. The winds on Neptune may be the fastest in the entire solar system.
No, Neptune is a planet. Stars are hot, glowing with the heat from nuclear fusion in their core. Neptune is cold, and much too small to have fusion.
Neptune radiates MORE heat that it receives from the Sun - the reason is still unknown. Possible reasons are atmospheric interaction or magnetic waves.

Neptune. It is the farthest planet from the sun
No. Cold cannot radiate, only heat can. This is because cold is not a thing unto itself but is simply the relative absence of heat. While it is very cold, Neptune actually radiates more heat than it receives from the sun. If it were not for this it would be even colder.
Neptune or Uranus is the coldest Planet. Some reference sources say it's Neptune others say it's Uranus. There's very little difference between them. Neptune is the furthest from the Sun, but it has an internal heat source.
Yes it does but no one knows why
Because Neptune does have a heat source. It generates about 2.6 times more energy that it receives from the Sun. This may be due to radiogenic heating [See related link] but we're not too sure.
The heat of the planets decrease the further from the sun they are. Mercury being the warmest planet and Neptune being the coldest.
Neptune is because its the farthest planet away from the Sun. Comment : Uranus is just about the coldest planet, because Neptune has an internal heat source.
Since the Neptune Orbit so far from the sun, it receives very small amount of heat and indeed the uppermost region of the atmosphere is -218 °C (55 K). There is no solid surface due to the fact that Neptune is a gas giant. Atmospheric temperatures gradually rise as you go deeper inside Neptune due to an internal source of heat. It is thought that this may be leftover heat generated by in falling matter during the planet's birth, right now slowly radiating away into space. Neptune's atmosphere has the highest wind speeds in the solar system, up to 2000 km/h, thought to be powered by this flow of internal heat. The internal structure resembles that of Uranus.
