We all know why mercury is extremely hot and have a valid reason. But It is also proved that its surface is extremely cold also like temperature fell up to -170degrees.
On the day its temperature is around 840-degree Fahrenheit (451-degree Celsius) but at night it goes minus 275 Fahrenheit (-170 degrees Celsius.)
You can see a change of temperature of nearly 1100 degrees Fahrenheit (600-degree Celcius).
It’s all because of Mercury’s thin atmosphere that can not maintain the heat that it gets in the day and because of its huge day and night.

Fun fact: Mercury is nearly 3 times closer than Earth to the sun.
We have sent many space explorers but after all this we know very little about it like do you know that on Mars you will live long because of its weak gravity? Or that inside Earth there can be 6 Mars can live? but after all these they both have nearly the same landmass.
Mercury is almost perfectly tidally locked to the Sun. That’s why there is such a dramatic temperature gradient. Has nothing to do with atmosphere, because in our sense of the word it hasn’t got any.
Hardly "perfect:"
Mercury rotates in a way that is unique in the Solar System. It is tidally locked with the Sun in a 3:2 spin–orbit resonance, meaning that relative to the fixed stars, it rotates on its axis exactly three times for every two revolutions it makes around the Sun.

Regards,
Climate change... Guess Greta and the climate folks should go there and fix it.
Ancient Mercurians thought SUVs were cool and this is what happened!
More fun facts: Being 1/3 the distance from the Sun, the inverse square rule of irradiance says it receives NINE times the radiation that the Earth does.
Mercury’s orbit is so elliptical that the distance to the sun ranges from 29 to 43 million miles. Compared to Earth’s fairly consistent 93 million miles from the sun, the irradiation varies from around 9 times to about 4 times ours over the course of their year. Nutty place.
You should see how much and how quickly my wife can change.
An individual point on Mercury has “no day and night.”
Mercury is gravitational locked to the sun so it presents the same face to the sun constantly. Mercury has a sun side and a dark side. The sun side is hot as hell and the dark side makes the antarctic seem a tropical paradise.
Our moon is also gravitational locked to the earth.
Makes me sweat just thinking about it. Or maybe I’m frigid...
‘Face
;o]
Yeah, but emotionally the relationship runs hot to cold.
Oh yea....but of course. /sarc.
I learn more on FR that any other place. Thank you.
