what is the average nightly temperature on earth
temp. ranges from 425 degrees in the day to -170 degrees at night. From the night, Mercury's surface temperature changes 1,130 Â°F (630 Â°C), more than any other planet â¦ or moon in the solar system. Just before sunrise on a typical day on Mercury the temperature is -300 Â°F (-180 Â°C).By midmorning the temperature rises to 80 Â°F (27 Â°C).hile there is day on one side of the Earth, we have night on the other side, i.e. we always have both day and night on the Earth. In that sense, there is no answer to this qu â¦ estion.   A: It's about 63 degrees Fahrenheit.
