90 F to Kelvin, halved and converted back, is approximately -190.
It’s difficult to find data on what exposure to that temperature would do, the threshold for an extreme cold warning (meaning absolutely do not go outside without heavy protection unless you want necrotic frostbite) is about 150 F warmer than that.
It depends on conductive and convective transfer at that point. The atmosphere would be vastly different as that’s well below the point where CO2 would snow out but you should still have enough gasses to flash freeze you.
