# What would the approx. min and max temperatures be for Snowball Earth with no atmosphere?

(Asked by: username_0 on 2022-06-07)

I saw a similar previous question on this website about the temperature of the Earth with no atmosphere. It sounds like if the Earth did lose its atmosphere we’d end up with either Snowball Earth or slushy Snowball Earth.

In that thread someone said the new average temperature of the Earth would be around 274.5K.

What I’d like to know is, if Earth lost it’s atmosphere, what would the new minimum and maximum temperatures be?

According to NASA currently the Earth has min of -88C and a max of 58C.

I am wondering if the Earth’s new min max would be similar to the moon: -233C min and 122C max.
