Neptune, being the eighth planet in our solar system and therefore the one furthest from the sun, has the coldest average temperature (around -214°C). On the other hand, Uranus being the 7th planet farthest from the sun, holds the record for the coldest temperature reached, with a record of -224°C.
Is Uranus colder than Neptune?
It depends upon how you define “coldest.” With Pluto out of the race, the farthest “real” planet from the Sun is Neptune. … Scientists have been surprised to learn, though, that Uranus reaches colder temperatures despite the fact that Neptune, on average, is colder than Uranus.
Why is Uranus the coldest planet and not Neptune?
It is believed that Uranus exhibits an orbit with a tilt like no other planet. The tilt makes the planet spill out a lot of heat into the space thus retaining very little. Consequently it becomes colder than the other planets.
Which is the coldest of all planets?
Most agree that Neptune is the coldest planet due to its proximity to the sun. The sun produces most of the heat that helps planets regulate their temperatures. Neptune is so far away from the sun that it does not get enough heat to melt the ice caps that form on the planet.
Why Uranus is the coldest?
Currently, we believe that the planet tilted so severely after being pelted by massive celestial bodies following its formation. The blows forced the heat in its core to spill into outer space. In fact, Uranus’ core is so cold that it is the only gas giant that receives more heat than it produces.
What is the oldest planet?
At 12.7 billion years old, planet Psr B1620-26 B is almost three times the age of Earth, which formed some 4.5 billion years ago. This exoplanet, the oldest ever detected in our Milky Way galaxy, has been nicknamed “Methuselah” or the “Genesis planet” on account of its extreme old age.
What is the warmest planet?
Venus is the hottest planet in the solar system. Although Venus is not the planet closest to the sun, its dense atmosphere traps heat in a runaway version of the greenhouse effect that warms Earth.
Is Pluto colder than Neptune?
Home » Space Questions » What is the coldest planet? The short answer is that Neptune has the coldest overall average temperature and Uranus has the coldest temperature recorded. … Pluto was the planet furthest away from the Sun and also the coldest.
Does it rain diamonds on Uranus?
Deep within Neptune and Uranus, it rains diamonds—or so astronomers and physicists have suspected for nearly 40 years. The outer planets of our Solar System are hard to study, however. … Beyond the lingering mystery of the diamond rain, there’s a big loss in our failure to study Uranus and Neptune inside and out.
What is the hottest and coldest planet?
Shakeel Anwar

| 2. Mercury | 167 |
| 3. Earth | 15 |
| 4. Mars | -65 |
Can humans live any other planet?
Based on his Copernican principle, J. Richard Gott has estimated that the human race could survive for another 7.8 million years, but it is not likely to ever colonize other planets.
Which is the coldest planet in the world?
Neptune, being the eighth planet in our solar system and therefore the one furthest from the sun, has the coldest average temperature (around -214°C).
Why is Neptune so hot?
The energy that Neptune makes has been found to be very high. There are several ways in which astronomical objects make energy from inside. The first is by thermonuclear fusion, the way a star makes energy. Another method is by radioactive material within the ground, the way a planet makes energy.
Why is Uranus so hot?
Despite its distance from the Sun, the largest contributing factor to its frigid nature has to do with its core. Much like the other gas giants in our Solar System, the core of Uranus gives off far more heat than is absorbed from the Sun.
How cold is it on Uranus?
speeds on Uranus range from 90 to 360 mph and the planet’s average temperature is a frigid -353 degrees F. The coldest temperature found in Uranus’ lower atmosphere so far is -371 degrees F., which rivals Neptune’s frigid temperatures.
What is the coldest dwarf planet?
However, due to the IAU’s decision in 2006 to reclassify Pluto as a “dwarf planet”, the title has since passed to Neptune. As the eight planet from our sun, it is now the outermost planet in the solar system, and hence the coldest.
