Habitability in this usage means “a place where humans can live, either with or without technological assistance”. In terms of temperature, this means the range of temperatures where machinery can reliably function. Of the temperatures found in the universe, this machinery-functionable range is actually extremely narrow
There’s not really any data other than a rough distance from its star. The atmosphere could be thick enough and with the right combination of greenhouse gases that the temperature at the equator is 23°C year round. We do know that it’s only receiving ~30% of the energy from its star as earth does from the sun, which is what they’re basing the low temperature estimates on.
And it’s not like once we have the technology needed to travel 146 light years that we couldn’t do something insane like deploy mirror-film solar cells or something to capture extra heat in orbit around the planet and warm the entire planet and terraform it for our usage.
How the is -94 degrees in any way habitable?
Antarctica gets to -132?
Yeah and its not really habitable by humans. Its hard to just be there on Earth where there is oxygen.

Same way mars is.

The article itself also says -70 which, still very cold, is much better.
-70°C is -94°F

Once? I dont think any if that is close or even gauranteed.
