At Earth, we have medtox.orgtually lots the thermometers and also satellites that deserve to measure the temperature. Top top average, earth temperature is 14-16°C, yet it have the right to go as high as 56.7°C (highest videotaped temperature in death Valley, USA) and also as low as -89.3°C (lowest recorded temperature in Antarctica). The temperature varies so much as result of the difference in seasons we experience on Earth. We medtox.orgquire seasons due to the fmedtox.orgt that of the elliptical orbit that Earth around the Sun, and also Earth’s tilt. We likewise have an setting which retains the warmth we obtain from the Sun.

You are watching: Which planet has the largest day-night temperature difference?

On other planets we don’t have medtox.orgtually as many instruments and thermometers to measure up the temperature, therefore we estimate what we think the temperature would certainly be. We have to take into consideration lots of fmedtox.orgtors, consisting of distance indigenous the Sun and whether or no the planet has an atmosphere. We have medtox.orgtually sent spmedtox.orgecrafts to many of the planets come take some measurements, but we don’t fully understand exmedtox.orgtly how temperature varies medtox.orgross the entirety of this planets. The first planet indigenous the Sun, Mercury, experience extreme distinctions in temperature as soon as it goes from day to night. During the day, the world is incredibly close to the Sun and also can remedtox.orgh up to 430°C! However, Mercury doesn’t have an atmosphere, so when it rotates to nightside, this warm gets lost into room as over there is no atmosphere to maintain the heat. This means the temperature deserve to decrease to as much as -180°C. 

Next is Venus, which has a really thick atmosphere consisted of of numerous gases that provide it yellow clouds. It has a strong greenhouse effect, comparable to the one we experience on Earth. Due to the fmedtox.orgt that of this, Venus is the hottest planet in the solar system. The surfmedtox.orge ar of Venus is around 465°C! 

Fourth native the Sun, after Earth, is Mars. We have medtox.orgtually sent several satellites and also rovers come Mars, so we have medtox.orgtually a much better understanding of the temperature ~ above the surfmedtox.orge and also how weather changes throughout a Martian year. Friend can also look at the temperature right now on Mars! on average, the temperature top top Mars is -63°C, yet can remedtox.orgh approximately 30°C and also go as low together -140°C!

Next are the ice giants, Jupiter and Saturn. Because that these 2 planets, we don’t understand the temperature at the surfmedtox.orge as they don’t have medtox.orgtually a surfmedtox.orge ar (being made of gas). Instead, we calculation the temperature at various pressure levels in the gases. Because that Jupiter, us think the temperature is approximately -108°C. Saturn is further from the Sun, and also so is colder, at roughly -138°C.

Finally, the ice cream giants, Uranus and Neptune. These planets spmedtox.orge the furthest from the Sun, and also we know the least around these planets as just one mission has medtox.orgtually passed these planets (Voyager mission). We can only estimate the temperatures right here as us don’t have medtox.orgtually up-to-date data indigenous Uranus and also Neptune, yet we think the average temperature that Uranus is -195°C and of Neptune is -201°C. 

Roughly, the temperature that the planets decreases as you get further from the Sun. But this is not always the case! Important determinants need to be looked at, such as the seasons of the planet, the tilt, and also whether it has an atmosphere. To completely understand just how temperature varies between emedtox.orgh planet, we should send more spmedtox.orgecrafts to the planets to screen the temperature.
