How cold would Earth be without the sun?

And without sunlight, the Earth would get very, very cold. Earth’s surface temperature now averages about 57 degrees Fahrenheit, but by the end of the first week without the sun, the average surface temperature would be below the freezing point. Within a week, the average global surface temperature would drop below 0°F. In a year, it would dip to –100°

How quickly would the Earth cool without the sun?

The average temperature of the Earth’s surface is now around 300 Kelvin (K). This indicates the temperature will decrease to 150K in two months and 75K in four months. Water has a freezing point of 273 degrees Fahrenheit. So, in just a few weeks, it would be too cold for us humans.

It is a source of life for us on Earth. Temperatures seldom go below minus 50°C in Antarctica, the world’s coldest region. The temperature would be anywhere near negative 273°C if it weren’t for the sun’s rays. Life would never have been able to continue or even exist.
