What causes the temperature on Neptune to be so hot?
You are gravely mistaken. Neptune is not a hot planet and it never has been. Neptune is so far from the sun that the planet and its atmosphere are absolutely freezing. The average temperature of Neptune is −218 °C (55.1 K).
Why is Uranus colder than Neptune?
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.
Which of the planets does not give off a lot of heat?
Neptune. It is the farthest planet from the sun
What is the second coldest planet explain how you know?
Neptune is the second coldest planet in our solar system after Uranus. This is because Neptune is farther from the Sun compared to Uranus, causing it to receive less heat and have lower temperatures. Additionally, Neptune's atmosphere is composed mostly of gases that can trap heat, preventing it from escaping and contributing to its cold temperatures.
How can Neptune have 1000 mph winds with out a heat source?
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.
Is Neptune a sun?
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.
What causes the temperature on Neptune to be so hot?
You are gravely mistaken. Neptune is not a hot planet and it never has been. Neptune is so far from the sun that the planet and its atmosphere are absolutely freezing. The average temperature of Neptune is −218 °C (55.1 K).
Does Neptune radiate less heat than it the receives from the sun?
Neptune radiates MORE heat that it receives from the Sun - the reason is still unknown. Possible reasons are atmospheric interaction or magnetic waves.
Why is Uranus colder than Neptune?
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.

Which is the coldest planets?
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.
Does cold radiate from Neptune?
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.
Does neptune have its own internal heat source true or false?
Yes it does but no one knows why
What is the heat of the planets in order?
The heat of the planets decrease the further from the sun they are. Mercury being the warmest planet and Neptune being the coldest.

What are physical charateristics of Neptune?
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.
