Why is Neptune considered the coldest planet?
This is because it is the eighth planet in our solar system and therefore the furthest away from the Sun. The Sun is our primary heat source so it would make sense that the planet with the greatest distance from it would be the coldest. Neptune is known as an Ice Giant and for a good reason.
Is Neptune the coldest planet?
You might think, then, that the coldest planet in the Solar System would be Neptune, as it is the furthest away from the Sun’s warmth. Neptune is an incredible three billion miles away from the Sun. However, the coldest planet is not Neptune, but Uranus – even though Uranus is a billion miles closer to the Sun than Neptune.
What is the minimum and maximum temperature on Neptune?
What is the minimum and maximum temperature on Neptune? All told, the planet experiences temperatures that range from approximately 55 K (-218 °C; -360 °F) to 72 K (-200 °C; -328 °F), making it the coldest planet in the Solar System. Hereof, what is the highest and lowest temperature on Neptune?
Is Neptune the windiest planet?
Neptune is the windiest planet in our solar system, whipping up momentous gusts that can reach more than 1,200 miles an hour. What planet rains diamonds? 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.
What is Neptune's highest and lowest temperature?

How hot and cold can Neptune get?
At 2.8 billion miles (4.5 billion km) from the sun, Neptune is, unsurprisingly, an intensely cold place, all the time. Even with variations, the average temperature is still a bone-freezing -364 degrees Fahrenheit (-220 degrees Celsius).
Does it rain diamonds on Neptune?
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. Only a single space mission, Voyager 2, has flown by to reveal some of their secrets, so diamond rain has remained only a hypothesis.
What is the hottest planet?
VenusIt has a strong greenhouse effect, similar to the one we experience on Earth. Because of this, Venus is the hottest planet in the solar system. The surface of Venus is approximately 465°C!
What is the temperature of Neptune?
What Are the High and Low Temperatures on Neptune? Neptune is the coldest planet in the Solar System, maintaining a fairly consistent average of -200 degrees Celsius. Towards the planet's equator, temperatures can get as cold as -218 degrees Celsius, while temperature at the South Pole is about 10 degrees Celsius warmer.
How cold is Neptune?
Towards the planet's equator, temperatures can get as cold as -218 degrees Celsius, while temperature at the South Pole is about 10 degrees Celsius warmer. The discrepancy in temperature has to do with the fact that Neptune's South Pole is exposed to the sun. Since a year on Neptune is equal to 165 Earth years, ...
What is the temperature of Neptune?
What is the minimum and maximum temperature on Neptune? All told, the planet experiences temperatures that range from approximately 55 K (-218 °C; -360 °F) to 72 K (-200 °C; -328 °F), making it the coldest planet in the Solar System. Correspondingly, what is the highest and lowest temperature on Neptune? The average temperature on Neptune is ...
How hot is Neptune?
Keeping this in view, how hot or cold can Neptune get? The average temperature on Neptune is about minus 200 degrees Celsius (minus 392 degrees Fahrenheit). Neptune, the farthest known planet of our solar system, is located about 30 times farther away from the sun than Earth is.
How cold is Neptune?
At this point, the temperature of Neptune can reach as low as 55° Kelvin (or 50° above absolute zero) although the mean temperature of the planet is 73° K (-200° Celsius). However, temperatures at the South Pole are -10° C warmer than the rest of the planet because it is currently titled towards the Sun.
What is the atmosphere of Neptune made of?
The atmosphere of Neptune is composed mainly of helium and hydrogen, with large quantities of ice mixed in.
How far is Neptune from the Sun?
Now that Pluto has been demoted from a planet to a dwarf planet, Neptune is now the most distant planet in the solar system. It is 2.8 million miles from the Sun or 30 times the distance of the Earth to the Sun. Its distance has also made it, until recently, one of the most mysterious planets in our system. In fact, most of what we know about the planet comes from the Voyager 2 spacecraft, which passed by Neptune in 1989, although this has since been supplemented by ground-based and Hubble Space Telescope observations.
What is the name of the spacecraft that landed on Neptune?
In fact, most of what we know about the planet comes from the Voyager 2 spacecraft, which passed by Neptune in 1989, although this has since been supplemented by ground-based and Hubble Space Telescope observations.
Is Neptune a solid surface?
As expected, Neptune is one of the coldest planets in the solar system. The planet is an ice giant, meaning it doesn’t have a solid surface; its ‘surface’ is where the planet’s clouds meet space.
What is the maximum and minimum surface temperature of Neptune?
Scientists have defined the “surface” of Neptune as the region where the surface pressure is equivalent to the pressure on Earth at sea level. The temperature at this “surface” is approximately minus 346 F (minus 201 C). The planet’s average temperature is minus 353 F (minus 214 C).
What is the average high temperature on Neptune?
The average temperature on Neptune is about minus 200 degrees Celsius (minus 392 degrees Fahrenheit). Neptune, the farthest known planet of our solar system, is located about 30 times farther away from the sun than Earth is.
How hot and cold can Neptune get?
Neptune has the wildest and strangest weather in the entire Solar System. It has huge storms with extremely high winds. Its atmosphere has dark spots which come and go, and bright cirrus-like clouds which change rapidly. Neptune has an average temperature of -353 Fahrenheit (-214 Celsius).
What is the highest and lowest temperature 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.
Why is Neptune so cold?
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.
What are the 15 planets?
Mercury. Mercury—the smallest planet in our solar system and closest to the Sun—is only slightly larger than Earth’s Moon. …
What is the hottest planet in the universe?
Planetary surface temperatures tend to get colder the farther a planet is from the Sun. Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet.
What is the temperature of Neptune?
The average temperature on Neptune is a brutally cold -373 degrees F. Triton, Neptune's largest satellite, has the coldest temperature measured in our solar system at -391 degrees F. That is only 68 degrees Fahrenheit warmer than absolute zero, a temperature in which all molecular action stops.
What is the atmosphere of Neptune?
Neptune's thick atmosphere is mostly hydrogen, with smaller amounts of helium and methane.
How fast is Neptune?
The equatorial regions of Neptune possess average wind speeds of over 700 mph, which is faster than the speed of sound here on Earth. Like Jupiter and Saturn, Neptune radiates more hear than it receives. Therefore it has an immense internal heat source. It is hypothesized that Neptune's internal heat source adds to vertical convection, ...
What is the Great Dark Spot on Neptune?
But upon closer inspection, it is likely that Neptune's "Great Dark Spot" is a hole in the methane cloud deck, similar to the ozone hole experienced on Earth.
