Uranus holds the record for the coldest temperature ever measured in the Solar System: a very chilly -224℃. The temperature on Neptune is still very cold, of course – usually around -214℃ – but Uranus beats that. The reason why Uranus is so cold is nothing to do with its distance from the Sun.

What planet is cooler than Earth?

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.

What is the coldest planet to Earth?

Uranus holds the record for the coldest temperature ever measured in the solar system: a very chilly minus 371 degrees Fahrenheit (minus 224 degrees Celsius), according to NASA (opens in new tab) .

Which is colder Earth or Jupiter?

Earth - 59°F (15°C) Mars - Minus 85°F (-65°C) Jupiter - Minus 166°F (-110°C) Saturn - Minus 220°F (-140°C)

Is Mars the coldest planet?

Mars is the coldest of the inner rocky planets, and it orbits just outside the Sun's habitable zone at an average distance of 142-million miles (228-million kilometres). At such a vast distance, it's no surprise that Mars is colder than the Earth.

Is Uranus cold or hot?

Uranus' planetary atmosphere, with a minimum temperature of 49K (-224.2 degrees Celsius) makes it even colder than Neptune in some places. Wind speeds can reach up to 560 miles per hour (900 kilometers per hour) on Uranus.

Is Neptune colder than Uranus?

Even though Uranus is usually slightly warmer than Neptune, it does reach the coldest temperatures of any planet. The coldest temperature ever recorded for Uranus was -371º F! Scientists aren't completely sure why Uranus reaches such cold temperatures despite being so much closer to the Sun than Neptune.

Is Saturn cold or hot?

On the surface, Saturn's average temperature varies from about -185 degrees Celsius (-300 degrees Fahrenheit) to -122 C (-188 F). The temperature variation is due to the planet's internal processes, not the sun.

Is Mars Hot or cold?

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.

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!

Is Uranus colder than Antarctica?

Temperatures on the Earth can drop as low as -148 degrees Fahrenheit on Antarctica and fall below zero in certain regions. Neptune is the coldest planet in the universe and sees temperatures of below -210 degrees Celsius. Uranus is the next coldest planet but can experience temperatures below those reported on Neptune.

Is Neptune hotter than Uranus?

"We can only measure temperatures in the outermost layers," said Michael Wong, a planetary scientist at the University of California, Berkeley, via email. In doing so we find that Neptune isn't actually hotter than Uranus in real terms — they're essentially at the same temperature.

Is Neptune cold or hot?

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. Only about one thousandth of the sunlight received by our planet reaches Neptune.

Why is Uranus coldest?

The reason why Uranus is so cold is nothing to do with its distance from the Sun. Billions of years ago, something big crashed into Uranus with so much force that it tipped the planet over onto its side. Uranus still rolls around the Sun on its side today.

How cold is it on Pluto?

Surface. 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.

How cold is the moon?

The average temperature on the Moon (at the equator and mid latitudes) varies from -298 degrees Fahrenheit (-183 degrees Celsius), at night, to 224 degrees Fahrenheit (106 degrees Celsius) during the day.

Is Pluto hot or cold?

All planets have temperature changes related to their seasons; some changes are more extreme than others. At its warmest, when it is closest to the sun, Pluto can reach temperatures of minus 369 degrees Fahrenheit (minus 223 degrees Celsius). At its coolest, temperatures can fall to minus 387 degrees F (minus 233 C).

Is Mercury hot or cold?

It is understood that the sunny side may reach temperatures of 750 to 800 degrees F., while the nighttime temperature plummets to nearly -330 degrees F. The average temperature on Mercury is a balmy 354 degrees F.

Is Venus hot or cold?

It appears that the surface temperature ranges from about 820 degrees to nearly 900 degrees F. The average surface temperature is 847 degrees F., hot enough to melt lead.

What is the coldest dwarf planet?

And when New Horizons took Pluto's temperature, the dwarf planet was cold — colder, even, than anyone had predicted. Researchers were puzzled. Earthbound instruments gauged Pluto to be minus-280 degrees Fahrenheit. New Horizons showed that Pluto's thermostat was dialed to 330 degrees below.

Does Uranus rain 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.

Which is colder Saturn or Uranus?

With a temperature of -357 degrees Fahrenheit, Uranus is the coldest planet in the solar system.

Is Jupiter hotter than Earth?

With an average temperature of minus 234 degrees Fahrenheit (minus 145 degrees Celsius), Jupiter is frigid even in its warmest weather. Unlike Earth, whose temperature varies as one moves closer to or farther from the equator, Jupiter's temperature depends more on height above the surface.

Does it snow on Mars?

Yes. In fact, snow has already been detected falling on Mars – though up in its atmosphere rather than settling on the ground. In 2008, NASA's Mars Phoenix Lander detected snow falling from clouds about 4km (13,000ft) above the planet's surface.
