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.
Neptune is the second coldest planet, Uranus's atmosphere makes it the coldest planet with temperature of minus 224 deg. celcius.
Jupiter - Minus 166°F (-110°C) Saturn - Minus 220°F (-140°C) Uranus - Minus 320°F (-195°C)
Venus, which can be seen with the unaided eye fromEarth, is the brightest planet in our Solar System.
Jupiter's environment is probably not conducive to life as we know it. The temperatures, pressures, and materials that characterize this planet are most likely too extreme and volatile for organisms to adapt to.
The Klinck weather station holds the record for the coldest place in the Arctic Circle. Located in central Greenland, it beat the previous record held by Oymyakon (see below) by around 2 degrees in December 1991, reaching -69.6°C. Despite these cold temperatures, much of Greenland's ice is melting rapidly.
Mariner 4, which flew by Mars on July 14, 1965, found that Mars has an atmospheric pressure of only 1 to 2 percent of the Earth's. 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.
Astronomers have discovered that a distant planet is both. With one side always hot as lava and the other chilled possibly below freezing, Upsilon Andromeda b is a giant gas planet [image] that orbits extremely close to Upsilon Andromeda, a star 40 light-years from our solar system in the constellation Andromeda.
The diamond rain phenomenon is believed by some scientists to take place on Uranus and Neptune in our solar system. It is thought it exists some 8,000 km below the surface of our ice giant neighbours, created from commonly found mixtures of hydrogen and carbon, squeezed together at incredible pressure.
Why is Uranus so cold? The big problem is that Uranus isn't generating any heat. The other giant planets in the Solar System actually give off more heat than they receive from the Sun. This is because they're slowly compacting down, and this generates high temperatures inside their cores.
But, Uranus's spin axis is tilted by a whopping 82 degrees! This gives rise to extreme 20-year-long seasons and unusual weather. For nearly a quarter of the Uranian year (equal to 84 Earth years), the sun shines directly over each pole, leaving the other half of the planet plunged into a long, dark, frigid winter.
Mars once ran red with rivers. The telltale tracks of past rivers, streams and lakes are visible today all over the planet. But about three billion years ago, they all dried up—and no one knows why.
Lastly, Uranus is extremely cold, but it's not the coldest celestial body in the Solar System. Pluto, which was relegated to the status of a dwarf planet in 2006, is colder, for the simple reason that it is the furthest body from the Sun.
It is estimated that the temperature of the cloud tops are about -280 degrees F. Overall, Jupiter's average temperature is -238 degrees F. Since Jupiter is only tilted slightly more then 3 degrees on its axis, seasonal fluctuations are minimal.
Oxygen makes up one-fifth of the air we breathe, but it's the most vital component – and it does seem to be declining. The main cause is the burning of fossil fuels, which consumes free oxygen. Fortunately, the atmosphere contains so much oxygen that we're in no danger of running out soon.
While the red planet's thin atmosphere and bitter cold temperatures keep these frozen clouds from ever falling in the form of rain and snow we see here on Earth, there is actually a type of precipitation on Mars. "This precipitation most likely takes the form of frost," NASA explains.
For example, like Earth, Mars has seasons, meaning seasonal changes in its atmosphere and weather. But the Martian atmosphere is much thinner than Earth's, meaning atmospheric pressure is so low that the blood of any unprotected visitor would boil.
Extremely remote and set in the far north of Ethiopia, Dallol is a tiny village known for setting records. It's the hottest year-round spot in the world, with the average annual high temperature coming in at a blistering 106.1 degrees F.
What is the hottest temperature ever recorded on Earth? The highest temperature on record belongs to California's Death Valley which, in 1913, reached a temperature of 134 degrees Fahrenheit, or 56.7 degrees Celsius, Al Jazeera reports.
Potential for Life
The surface of Pluto is extremely cold, so it seems unlikely that life could exist there. At such cold temperatures, water, which is vital for life as we know it, is essentially rock-like. Pluto's interior is warmer, however, and some think there could even be an ocean deep inside.
Surface. As a gas giant, Saturn doesn't have a true surface. The planet is mostly swirling gases and liquids deeper down. While a spacecraft would have nowhere to land on Saturn, it wouldn't be able to fly through unscathed either.
