It is here on Neptune, just below the upper level clouds, that pressures reach between 1 and 5 bars (100 – 500 kPa). It is also at this level that temperatures reach their recorded high of 72 K (-201.15 °C; -330 °F).
What is the highest and lowest temperature on 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.
How hot does it get 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 Neptune’s lowest temperature in Celsius?
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 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. 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 are the 15 planets?

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.
Is Neptune a gas giant?
Neptune is the eight planet from our Sun, one of the four gas giants, and one of the four outer planets in our Solar System.
How long is 1 day on Neptune?
0d 16h 6m
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.
Is Neptune all water?
Structure. Neptune is one of two ice giants in the outer solar system (the other is Uranus). Most (80 percent or more) of the planet’s mass is made up of a hot dense fluid of “icy” materials—water, methane and ammonia—above a small, rocky core.
What is the hottest planet?
Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)
Is Uranus a cold or hot planet?
The seventh planet from the sun, Uranus has the coldest atmosphere of any of the planets in the solar system, even though it is not the most distant. Despite the fact that its equator faces away from the sun, the temperature distribution on Uranus is much like other planets, with a warmer equator and cooler poles.
How cold can Uranus get?
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. Findings from Hubble reveal that clouds circle Uranus at over 300 mph.
