The coldest planet in our solar system on record goes to Uranus which is closer to the Sun and ‘only’ about 20 times further away from the Sun than the Earth is. The lowest temperature recorded there was minus 224 degrees Celsius.
How warm can Neptune get?
At its core, Neptune reaches temperatures of up to 7273 K (7000 °C; 12632 °F), which is comparable to the surface of the Sun.
Can we swim on Neptune?
Being an ice giant, there is no water on the surface of Neptune. Having a surface temperature of −201 oC any water on Neptune will be frozen. Extraterrestrial liquid water is believed to be beneath the ice surfaces of the Jovian moons Europa and Ganymede.
Is Uranus cold?
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 planet is Uranus?
Uranus is the seventh planet from the Sun, and has the third-largest diameter in our solar system. It was the first planet found with the aid of a telescope, Uranus was discovered in 1781 by astronomer William Herschel, although he originally thought it was either a comet or a star.
Why is Neptune so hot?
“The extra heat source on Neptune [and Jupiter and Saturn] is largely due to gravitational contraction,” said Joshua Tollefson, also of the University of California, Berkeley.
How cold is it on Pluto?
Pluto’s surface is characterized by mountains, valleys, plains, and craters. The temperature on Pluto can be as cold as -375 to -400 degrees Fahrenheit (-226 to -240 degrees Celsius). Pluto’s tallest mountains are 6,500 to 9,800 feet (2 to 3 kilometers) in height.
Does it rain diamonds in 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 if you fell into Saturn?
So, if you tried to walk on this part of Saturn, you would sink through its atmosphere. Saturn’s atmosphere is very thick and its pressure increases the deeper you go. After a while, you would stop sinking and unfortunately be crushed by the high pressure deeper in Saturn’s atmosphere.
What happens if we fall into Neptune?
Smooth and solid as it might seem, Neptune is in fact a large gas planet, so it would be physically impossible to stand on it. The only surface where you could theoretically actually stand on, is Neptune’s rocky and icy core. But even then you would immediately freeze to death due to the low temperatures.
Can you walk on Pluto?
If a person wanted to actually walk on the surface of Pluto, the astronaut would probably need to add a significant amount of weight to his gear in order to keep his feet firmly enough on the surface of the planet to actually walk around.
Why is Mars so hot?

In orbit, Mars is about 50 million miles farther away from the Sun than Earth. That means it gets a lot less light and heat to keep it warm.
What planet is the hottest?
Because of this, Venus is the hottest planet in the solar system. The surface of Venus is approximately 465°C! Fourth from the Sun, after Earth, is Mars.
Why is Neptune so cold?
Neptune lacks a solid surface as such and instead has an icy water layer that serves as the planet’s mantle. This makes finding a surface temperature difficult, but research conducted from Earth and fly by missions have managed to take this average temperature from the upper atmosphere.
How cold is the moon?
When sunlight hits the moon’s surface, the temperature can reach 260 degrees Fahrenheit (127 degrees Celsius). When the sun goes down, temperatures can dip to minus 280 F (minus 173 C). There are also no seasons on the Moon.
How cold is Jupiter?
The temperature in the clouds of Jupiter is about minus 145 degrees Celsius (minus 234 degrees Fahrenheit). The temperature near the planet’s center is much, much hotter. The core temperature may be about 24,000 degrees Celsius (43,000 degrees Fahrenheit). That’s hotter than the surface of the sun!
How cold is Mars?
Temperatures on Mars average about -81 degrees F. However, temperatures range from around -220 degrees F. in the wintertime at the poles, to +70 degrees F.
